High-speed rail in Spain

High-speed railways in Spain have been in operation since 1992 when the first line was opened connecting the cities of Madrid, Córdoba and Seville. Unlike the rest of the Iberian broad gauge network, the Spanish High-speed network mainly uses standard gauge. This permits direct connections to outside Spain through the link to the French network at the Perthus Tunnel. High-speed trains run on a network of high-speed rail track owned and managed by ADIF (Administrador de Infraestructuras Ferroviarias), where the dominant service is AVE while other high speed services such as Avant, Alvia, Avlo, Euromed, Ouigo España and Iryo, as well as mid-speed (Altaria) services also operate.

AVE trains are operated by Renfe, the national passenger high-speed rail operator in Spain, but private companies such as Ouigo España and Iryo compete on the Madrid–Barcelona and other routes in accordance with the European Union legislation. French TGV services run from the border to Barcelona under the TGV inOui brand. Some TGV-derived trains used to run on the broad-gauge network at slower speeds, branded by Renfe as Euromed, until new dual-gauge rolling stock was commissioned for these services. Alvia trains are also operated by Renfe and have the ability to use both Iberian gauge and standard gauge lines offering high-speed services across the whole Spanish network.

As of September 2024^[update], the Spanish high-speed rail network is the longest HSR network in Europe with 3,973 km (2,469 mi)^[1] and the second longest in the world, after China's.

It has been suggested that this article be split into a new article titled History of rail transport in Spain. (discuss) (November 2022)

Towards the end of the 1980s a new line was planned to join the Meseta Central with Andalusia without passing through the Despeñaperros pass. After considering various options it was decided that a standard-gauge line, allowing for Spain's first high-speed rail link, would be built. The project was named NAFA (Nuevo Acceso Ferroviario a Andalucía, New Rail Link to Andalusia) and was meant to help revitalise the stagnant southern Spanish economy. The line was inaugurated on 14 April 1992 to coincide with Expo 92 being held in Seville. Seven days later, on 21 April 1992 commercial AVE service began with six daily services stopping at Madrid, Seville, Córdoba, Puertollano and Ciudad Real.

In October 1992 Renfe began the AVE Lanzadera (Shuttle), a high-speed medium distance service between Madrid, Ciudad Real and Puertollano, using spare class 100 trains.

It has been suggested that the PSOE government chose the French Alstom bid over the Siemens and Talgo bids for political rather than technical reasons, rewarding the French government for its assistance in capturing ETA activists who took "sanctuary" across the border in southern France.^[2][3] Seville's hosting of the 1992 World's Fair prompted the choice of that city for the inaugural of the first high-speed line, with its being the home town of then Spanish prime minister Felipe González also playing some role. Seville was the artistic, cultural, and financial capital of southern Spain and the fourth largest city in Spain, after Madrid, Barcelona and Valencia, with a population of over 700,000 and a metropolitan area of almost 1.5 million people. It is also the capital of Andalusia, Spain's most populous autonomous community (region).

In January 1993 the Talgo 200 Madrid–Málaga service began, using high-speed lines as far as Córdoba and then the Córdoba–Málaga Spanish-gauge conventional track to reach Málaga. On 23 April that year, an AVE trainset set a new top speed of 356.8 km/h (221.7 mph) on a test run. Later in 1993 the mixed-method services Talgo 200 Madrid–Cádiz and Talgo 200 Madrid–Huelva began.

In 1994 AVE trains on the Madrid–Seville line began to run at 300 km/h, cutting journey times by at least 40 minutes and covering the 471 km in 2+1⁄2 hours, though it is unlikely that much of a saving came from the increase in maximum speed, because only a small section of the line near Los Yébenes has the alignments for 300 km/h operation. The maximum permitted speed is 270 km/h between Atocha station and Brazatortas, save for the approaches to the intermediate stations (Atocha, Ciudad Real and Puertollano). Beyond Brazatortas, the line is only authorised for 250 km/h operation, which drops to 215 km/h in the Sierra Morena mountains and 90 km/h around Córdoba station.^[4] It is more likely that time savings occurred as a result of there being fewer intermediate stops.

Although in 1999 Renfe began a mixed-service Talgo 200 Madrid–Algeciras route, this was, along with the other mixed services, transferred to Grandes Líneas Renfe (Renfe's Spanish gauge long-distance brand) following changes to plans for high-speed rail in Spain.

In November 2003 a new AVE Lanzadera medium distance service began between Seville and Córdoba using new class 104 trains,^[5] reducing journey times between the two cities to 40 minutes. In 2005 the brand was renamed RENFE Avant, and all those services started to use class 104 trains, leaving class 100 for the AVE services.

The construction of a 21-kilometre (13 mi) stretch of high-speed line from Madrid to Toledo allowed the inauguration of a medium distance service in November 2005. The journey time between the two cities is now less than 30 minutes. The high-speed link combined with high property prices in Madrid has encouraged many Madrid commuters to settle in Ciudad Real, the first stop on the Madrid–Seville line. There has, however, been controversy over the construction of this line as the change to standard-gauge track meant that towns such as Getafe, Aranjuez and Algodor, which now have no commercial services, lost their direct services to Toledo. Furthermore, since Toledo is now connected by standard-gauge track it is impossible for other passenger or goods trains to reach it that have not come from other high-speed lines.

The last segment of the Madrid–Málaga high-speed rail line was completed on 24 December 2007 when the new high speed railway section between the cities of Córdoba and Málaga was inaugurated. It is a standard gauge railway line of 155 km in length and is designed for speeds of 300 km/h (186 mph). It has compatibility with neighbouring countries' railway systems as well.

In October 2015 an extension of the Madrid-Seville high-speed rail line to Cádiz was completed after 14 years of works and put in service by Alvia trains for speeds up to 200 km/h.^[6]

In 2019 the Antequera–Granada high-speed rail line opened at a total cost of €1.4 billion.^[7]

The Madrid–Zaragoza –Barcelona line was inaugurated on 20 February 2008, after parts of the line had operated since 2003 (Madrid–Zaragoza–Lleida) and 2006 (Lleida–Tarragona). This line is currently one of the world's fastest long-distance trains in commercial operation,^[8] with non-stop trains covering the 621 km (386 mi) between the two cities in just 2 hours 30 minutes, and those calling at all stations in 3 hours 10 minutes. The line includes a spur railway that branches off at Zaragoza towards Huesca in north Aragon. The Madrid-Huesca high-speed rail line was inaugurated in 2005.

The line currently terminates at Barcelona Sants railway station, but a new station is under construction at La Sagrera on the northern edge of the city. The Sants–La Sagrera tunnel links the Barcelona Sants station in Barcelona with the future Sagrera station through the Eixample district. The tunnel passes under and along the streets of Provença and Mallorca, while uses a short part under Diagonal avenue to link between these two streets. In the Carrer de Mallorca street, the tunnel passes directly in front of Gaudí's masterpiece, the basilica of the Sagrada Família, and in the Carrer de Provença street, near another Gaudí's architectural work, the Casa Milà. In a long campaign against this route, the Board of the Sagrada Família and other parties argued that the tunnel would damage the church, whose construction is still in progress. In this discussion about different possible routes, the one now built is also called the Provença tunnel because part of its route passes under the street of the same name.

The tunnel boring machine Barcino passed the Sagrada Família in October 2010, and reached its final destination a few months later. In March 2012, railway equipment was installed, with a special elastic isolation of the rails in order to dampen vibrations at the sections passing close to Gaudí's architectural works, using the Edilon system. Rail traffic was planned to start in 2012, initially without stops at the La Sagrera station, which was expected to be completed in 2016.^[9][10] The Sants–La Sagrera tunnel was finally inaugurated on 8 January 2013 along with the Perpignan–Barcelona high-speed rail line while commercial services via the tunnel towards France begun on the following day.^[11] However, works on the Sagrera station suspended in early 2014 due to a corruption scandal involving one of the companies carrying out the works.^[12][13][14] Construction works at the station were finally resumed in 2018^[15] and the new AVE station is now expected to open to services by end 2026, while AVE trains will start passing through the station by end 2024.^[16]

The first installment of a high-speed rail corridor in the north and north-west of Spain was the 179.6 km section Madrid–Segovia–Valladolid which was put in operation on 22 December 2007. It includes a tunnel of 28 kilometres (17 mi) at Guadarrama, which is the fourth longest train tunnel in Europe. Valladolid will become the hub for all AVE services connecting the north and north-west of Spain with the rest of the country.

Construction of the extension of the line towards the region of Asturias started in 2009 (except for Pajares Base Tunnel (variante de pajares) which started in 2003) and reached the city of Leon in 2015 with the inauguration of the 162.7 km Valladolid–Venta de Baños–Leon section on 29 September 2015.^[17] On 29 November 2023 the section Leon-La Robla-Pola de Lena was inaugurated after 20 years of works^[18][19] On 21 May 2024 Renfe replaced the Madrid–Gijón and Castellón/Vinaros–Gijón Alvia services by AVE services on the first AVE gauge-changing Class 106 trains, able to operate at max speed 330 km/h or 205 mph with reduced journey times by 12 minutes between Madrid and Oviedo and by 10 minutes between Madrid and Gijón.^[20]

On 24 April 2010, it was announced a 55 km high-speed spur would leave the Madrid–Valladolid route at Segovia and continue to Ávila. Initial plans were expected to be complete by the end of 2010 but as of 2024 this line remains in plans.^[21]

On 21 July 2022 a new 86.5 km section between Venta de Baños and Burgos was inaugurated after 13 years of works at an investment cost of 759 million euros and introduced a new AVE Madrid-Burgos service that cuts the journey time between the two cities down to just over an hour and a half. This section is the first expansion of the high-speed network to the north-northeast towards the Spanish region of the Basque Country and the future Basque high-speed railway line (Basque Y). It includes 2 tunnels and 12 viaducts, the longest of them passes over Pisuerga river and Autovía A-62 highway.^[22]

In the north-west of Spain the Madrid–Galicia high-speed rail line completed on 21 December 2021 after 20 years of works when the Olmedo–Zamora–Santiago de Compostela section was finished. This line is connected to the Madrid–Asturias high-speed rail line at Olmedo south of Valladolid.^[23][24]

Construction on the 87.1 km northernmost part of this section between the cities of Ourense and Santiago de Compostela began late 2004 and this part was inaugurated in December 2011.^[25] The 107 km southern section, between Olmedo (130 km north of Madrid on the Madrid–Asturias line) and Zamora entered revenue service on 17 December 2015 by Alvia trains.^[26] The 110 km new built section in the middle between Zamora and Otero de Sanabria near the town of Puebla de Sanabria was put in service on 26 October 2020, while the 119.4 km last remaining part between Puebla de Sanabria and Ourense which crosses some of Spain's most remote and fragile nature areas, was completed in end 2021.^[27][23][24] Up to that date the entire line was served by Alvia S-730 (Patito, max speed 250 km/h (155 mph)) trains.^[28][29]

This line is connected in the region of Galicia with the 156 km Atlantic Axis high-speed rail line that connects the cities of Vigo and A Coruña via Santiago de Compostela. Since 21 May 2024 AVE Madrid–Vigo and Madrid–La Coruña services on gauge-changing Class 106 trains are offered with reduced journey times by 18 minutes between Madrid and Santiago de Compostela and by 16 minutes between Madrid and Vigo compared to the Alvia services.^[20][30]

The Atlantic Axis was inaugurated in April 2015 while the section A Coruña–Santiago de Compostela opened in 2009 and was electrified in 2011.^[31] The new railway shortened the distance between the two cities by 22 km, from 178 km to 156 km, and cut the travel time from around 3 hours on the old railway down to 1 hour and 20 minutes on the new one. 37 tunnels totalling 59 km and 34 bridges totalling 15 km form part of the rebuilt railway.^[32]

The Madrid–Levante network connects Madrid with the Mediterranean coast of the Levante Region (Eastern Spain). The Madrid–Cuenca–Valencia line was officially finished on Friday, 10 December 2010,^[33] with commercial trips starting on Saturday 18 December 2010. Non-stop trains between Madrid and Valencia cover the 391 km (243 mi) in 1 hour 38 minutes.^[34] The Madrid–Albacete–Alicante line was inaugurated on 17 June 2013. Trains cover the distance between Madrid and Alicante in 2 hour 12 minutes. On 22 January 2018 the extension section of the line to Castellón was inaugurated introducing a new AVE service Madrid-Castellón which cut the journey time between the two cities by further 30 minutes to total 2 hours and 25 minutes.^[35][36] The first stretch of the AVE service from Madrid to Murcia was inaugurated on 1 February 2021,^[37] linking Monforte del Cid, Elche and Orihuela, while the continuation up to Murcia put in service on 20 December 2022.^[38] Work is being prepared to extend the line to Cartagena. When fully operational the Madrid–Levante network will total 955 km of high-speed rail connecting Madrid, Cuenca, Albacete, Valencia, Alicante, Elche, Castellón, Murcia and Cartagena.^[39][40]

An important milestone for the Spanish high-speed network was reached in December 2013 when it was connected to the rest of Europe via France.^[41][42] The connecting link was the construction of the 131-kilometre (81.4 mi) Barcelona–Figueres section of the Perpignan–Barcelona high-speed line, an extension of the Madrid–Barcelona line, completed in January 2013 at a cost of €3.7 billion.^[11][43][44] The international 44.5-kilometre (27.7 mi) Perpignan–Figueres section of the line opened in December 2010 and includes the new 8.3-kilometre (5.2 mi) Perthus Tunnel under the Pyrenees.^[45]

The high-speed Barcelona-Figueres section (from Barcelona to the French border) was officially inaugurated in January 2013.^[46] The journey from the centre of Barcelona to the centre of Girona takes now 37 minutes (compared to the previous 90 minutes), and to Figueres in 53 minutes (instead of two hours). Girona and Figueres are now 14 minutes from each other. The Perpignan (France)-Figueres section opened in 2010. One lacking high-speed section on the French side, between Montpellier and Nîmes, opened in July 2018, allowing almost continuous high-speed travel from the French high-speed network to the Spanish one.^[47] The French government, on the other hand, recently announced indefinite delays to the Montpellier-Perpignan high speed section that was originally planned for 2020.

On 24 April 2010, tunnelling started on the 7.3 km route connecting the 2 main stations in Madrid, Madrid Atocha and Madrid Chamartín.^[21] Electrification works for the line along with line duplication works in the section between Atocha and Torrejón de Velasco started in 2017 and these works were expected to be completed in early 2018 and the line was hoped to open for commercial service for AVE trains within the same year.^[48][49] A later announcement postponed the opening for the second half of 2020. However, delays in the schedule due to the COVID-19 pandemic postponed it further.^[50] In November 2021, the inauguration of the interconnector was projected to the first trimester of 2022.^[51] Test runs were being conducted in early February 2022, and the line was expected to be ready for permit application in early March.^[52] The tunnel finally opened on July 1, 2022.^[53]

Before this all trains going towards Valladolid left from Chamartín and trains going to Seville, Málaga, Valencia, Alicante and Barcelona left from Atocha station. Also, there is a single daily service in each direction running along the Barcelona–Seville, Barcelona–Málaga, and Barcelona-Granada routes, which uses the high-speed bypass around Madrid to avoid reversing the direction of train in Atocha station. The tunnel now allows services serving northern cities to travel non-stop or with a stop through Madrid and onward to southern cities (or vice versa), without the driver having to change ends or bypass Madrid, a valuable source of passengers. Previously someone wanting to travel from Valladolid to Alicante, for instance, had to travel from Valladolid Campo Grande station to Madrid Chamartín station before taking a Cercanías service to Atocha; then finally taking an onward train to Alicante.

Currently there are five corridors with twelve main lines in operation, as well as two spur lines connecting the cities of Toledo with the Madrid–Seville main line and Huesca with the Madrid–Barcelona main line. Two more lines, one along the Mediterranean Corridor and one towards Extremadura are partially in operation for Alvia/Euromed services, since they are still under construction.

The Madrid–Galicia high-speed rail line connects the city of Madrid with the region of Galicia and the Atlantic Axis high-speed rail line in the North West of Spain via Segovia, Zamora, Puebla de Sanabria, Ourense and Santiago de Compostela. The line includes a new 424 km long high-speed railway section that starts at Olmedo 130 km to the north of Madrid on the Madrid–Leon high-speed rail line and ends at Santiago de Compostela. It was put in AVE service on 21 December 2021.^[23]

Currently there are six corridors with eleven lines under construction.

• León–La Robla

Madrid–Asturias high-speed railway is the line connecting Madrid to the region of Asturias in the north of Spain. The 20.2 kilometres (12.6 mi) section between León and La Robla remains in conventional Iberian gauge line for a maximum speed of 160 kilometres per hour (99 mph), that is due to be modernized to high-speed standards along with an additional standard gauge track by end 2024.^[97]

• Pola de Lena–Oviedo–Gijón

The northmost section of the Madrid–Asturias high-speed railway within the region of Asturias between Pola de Lena and Gijón is planned to be renovated by 2024. It has total length 62km.^[18][108]

• Burgos–Miranda de Ebro–Vitoria-Gasteiz^[109]

The extension of the Madrid–Valladolid section towards the Basque Country began construction in 2009. This 223.4 kilometres (138.8 mi) railway line will run parallel to the 244.8 kilometres (152.1 mi) long existing railway line. Originally it was to be used as a mixed-use high-speed railway line, but it has since been changed to a passenger-dedicated railway line, leaving the existing railway line for freight trains. The line was forecast to open the Valladolid–Burgos part around 2013 and the Burgos–Vitoria-Gasteiz part in 2014 or 2015. However, due to delays the line is not expected to open before 2028,^[98] although the Valladolid–Burgos section entered full revenue service in July 2022.^[22] At Vitoria it will be connected to the Basque high-speed railway line (Basque Y), thus reaching the French border. Once opened, the travel time between Valladolid and Vitoria will be around an hour.

• Bilbao–Vitoria-Gasteiz–San Sebastian–French border^[110]

The Basque high-speed railway line (Basque Y) will connect the three Basque capitals, Vitoria-Gasteiz, Bilbao and San Sebastián. Construction began in October 2006 and the line was originally forecast to open in 2016. However, due to delays in construction, later estimations forecast its completion in 2023^[111] but Adif's draft budget in end 2022 put again the completion of the Basque Y further to the year 2027.^[99] The three Basque capitals will be further connected with Madrid via Valladolid, and with the French border via Irun and Bayonne while a connection with Pamplona via two different alternative routes is currently in debate .^[99]

• Madrid–Segovia–Valladolid–Palencia–Reinosa–Santander

A new high-speed line is planned to branch off from the current Madrid–Leon high-speed rail line at Palencia and as a part of the north corridor will connect the region of Cantabria to the high-speed rail network with direct connection to Madrid. According to the plans the city of Santander will be connected via Villaprovedo and Reinosa. An agreement for completing the line by the end of 2015 was signed on 11 August 2010 including the agreement to call tenders for the section between Palencia and Villaprovedo before the end of March 2011 and for the Villaprovedo – Reinosa section before the end of 2012.^[112] However, construction works in the line started in November 2021 for the 20,8 km section between Palencia Norte and Osorno, while the section between Osorno and Reinosa was planned to be projected in 2022 and to start construction in 2023.^[113][100] In October 2022, construction approval was given by the Spanish government for the 20,7 km section between Osorno and Calahorra de Boedo,^[114] while tendering for the 13,7 km section between Calahorra de Boedo and Alar del Rey started in December 2022. As of 2023^[update] a total 78,4 km of the line in the part between Palencia and Alar del Rey are projected.^[115]

• Alicante–Murcia–Cartagena

This is an under construction section, part of the Madrid–Levante network of high-speed railways connecting the capital with the Mediterranean coast. Consisting of 955 kilometres (593 mi) of railways with an estimated cost of 12.5 billion euros, it is the most expensive high-speed railway project in Spain. The network will consist of both dedicated passenger high-speed railways designed for trains running above 300 kilometres per hour (190 mph) and high-speed railways shared with freight trains.^[39] The network is to be opened in stages, starting with the Madrid–Valencia/Albacete section, which was opened in December 2010,^[33][116] followed by Albacete–Alicante in June 2013,^[117] Valencia–Castellón in January 2018,^[35] Monforte del Cid–Orihuela in February 2021^[37] and reached the city of Murcia in December 2022,^[38] while a branch line to Cartagena is expected to follow by 2024. The section linking Valencia with Alicante in the Mediterranean Corridor was originally expected to open in 2022 but as of 2023 this is still pending.^[104]

• Transversal Rail Axis (Eje Ferroviario transversal de Andalucía),^[118] the Andalusian high-speed rail line connecting Huelva, Seville, Granada and Almería. Part of the line is financed and built by the Andalusian government.

The southern Andalusian transverse high-speed railway line is a 503.7-kilometre railway running between the cities of Huelva and Almería, passing the cities of Seville and Granada. The line is designed for speeds up to 250 kilometres per hour, except for the 130-kilometre Antequera–Granada and the 103-kilometre Seville–Huelva parts of the line, which are designed for speeds in excess of 300 kilometres per hour. A connection between Huelva and the Portuguese border is being studied.^{[citation needed]} When finished the journey between Huelva and Almería in the new line is estimated to last 3 hours and 35 minutes.^[119]

The first section Antequera–Granada was put in service on 26 June 2019 connecting the city of Granada to the rest of the high speed network via a branch from the Madrid–Málaga high-speed rail line.^[94] In March of 2024 the contract to build the last remaining high-speed section of this line, bypassing Loja, was awarded. ^[120]

Construction in the 128 km section between Seville and Antequera started in 2005 under the responsibility of the Regional Government of Andalusia on a route that includes Sevilla-Santa Justa, Seville Airport, Los Alcores Tunnel, Marchena, Osuna, Pedrera and Antequera-Santa Ana. However, since 2013 construction works are halted due to lack of funding with platform works in the 75 km section between Marchena and Antequera to be completed at a cost of 288 million euros, but with the remaining part between Sevilla-Santa Justa and Marchena to remain incomplete. As of 2023^[update] the Government of Andalusia is planning to start studies in order to find new financing possibilities and continue the project.^[121][122] Works in the section between Granada and Almería have not started yet and completion is forecast no earlier than 2030.^[102]

• Madrid–Alcázar de San Juan–Jaén

This high-speed railway line will be part passenger-dedicated high-speed railway (Madrid–Alcázar de San Juan) and part shared with freight trains (Alcázar de San Juan–Jaén). The first 99 km of the line will use the already existing Madrid-Seville high-speed railway line. From there, a 67.5 km branch line will be constructed towards Alcázar de San Juan.

From Alcázar de San Juan the existing railway line will be upgraded to allow passenger trains to run up to 250 km/h; a new double-tracked route through the Despeñaperros mountain range will be built to replace the existing single-tracked route. This part of the high-speed railway also forms part of the Madrid–Algeciras freight corridor.

Construction for this line was approved by the Spanish government on 15 July 2005 and works were planned to begin in 2008. However, works were paralyzed for years before they resumed in November 2017. The first section between Grañena and Jaén with a total length of 16,7 km was completed in March 2020.^[123][103]

An extension of the line to Granada is being investigated; however, the complicated terrain between Jaén and Granada might make it uneconomical.

• Tarragona–Valencian Community–Murcia Region–Almería

The railway linking Tarragona to Almería via Valencia and Murcia is expected to be completed by 2026 when the currently under construction 184 km Murcia–Almería high-speed rail line will be finished.^[105]

Its first 46,5 km new built cut-off part in Iberian-gauge track between Camp de Tarragona and Vandellòs started commercial services on 13 January 2020.^[124] A new dual-gauge high speed rail track on the 72 km part between Valencia and Castellón was inaugurated in January 2018.^[125] The section between Vandellòs and Castellón is an upgraded line of the old Iberian-gauge Valencia−Sant Vicenç de Calders railway currently used by the Euromed service in speeds up to 220 km/h that covers distance of 400 km between the cities of Barcelona and Valencia in 2 hours and 35 minutes.^[96] With a new line, it will take about 1 hour and 45 minutes on high speed trains to cover the same distance.^[126] However, this part is not under construction yet for a new standard-gauge high speed line.

The section linking Valencia with Alicante is expected to be completed by year 2025 at latest. The 52 km part between Torrent outside Valencia and Xàtiva, which is still under construction since October 2002, was initially expected to be completed by end 2020 and it is designed for speeds up to 350 km/h. Electrification works in the line were completed in December 2016.^[127] Modernization works for the 40 km single track in the remaining part between Xàtiva and La Encina Hub including conversion to standard-gauge high speed line for maximum speed of 260 km/h were expected to be completed by end 2022, but as of early 2023 they were still in testing phase.^{[104][128][129]} Since 9 September 2023 this section is closed to traffic in order additional works to take place for adding a double track.^[130] Works are now expected to be finished by late 2025.^[104]

The final section between Almería and Algeciras, passing through Málaga, will be built at a later point in time and an alternative and longer route looks likely.^[126]

• Madrid–Toledo–Talavera de la Reina–Plasencia–Cáceres–Mérida–Badajoz

This line was initially planned as Lisbon–Madrid high-speed rail line in order to connect the two peninsular capitals, Madrid and Lisbon in 2 hours and 45 minutes.^[131][132] This line had been a key issue in bilateral summits in recent years and was about to link Spain's high-speed rail network with the planned High-speed rail in Portugal, a project announced by the Portuguese government in February 2009. Construction on the Spanish side began in late 2008 on a segment between the cities of Badajoz and Mérida. Both Spanish and Portuguese track were to be completed around 2013, later the Portuguese government brought forward its plans from 2015 but the Portuguese froze works in June 2011 and eventually cancelled the project in March 2012.^{[133][134][135]} In 2016 the European Union's European Regional Development Fund, gave Spain €205.1m towards the €312.1m needed for the track between Navalmoral de la Mata and Mérida, Spain.^[136] The section on the Spanish side between Madrid and Badajoz was originally expected to be completed by 2023.^[137] However, according to new estimations the line is not expected to be completed before 2030.^[106]

With a length of 439 km on the Spanish side, of which 48 km are part of the already built Madrid–Seville high-speed rail line, the original plan was to connect cities like Talavera de la Reina, Navalmoral de la Mata, Plasencia, Cáceres, Mérida and Badajoz to Madrid.^[131] The Almonte River Viaduct was completed in May 2016 to carry this line. It is a concrete arch bridge with a span of 384 meters (1,260 feet), ranking among the longest in the world of this type of bridge.^[138][139] For the section between Madrid and Oropesa a new Informative Study was awarded by the Ministry of Public Works in February 2018 in order to propose alternative routes with lower environmental impact than those in the initial study from 2008.^[140] In November 2020 the new study was approved by the Ministry of Transport and in the revised proposal the city of Toledo was added in the route by the use of the existing high speed section between Madrid and Toledo. The new introduced 127 km section with budget of €1.3 billion starts from Toledo and passes through the cities of Talavera de la Reina and Oropesa until it reaches the border of the Province of Toledo with new stations planned in all those three cities.^[141]

The section between Plasencia and Mérida was originally planned to put in service by end 2021.^[142] However, the first part given to service was the entire 150 km section between Plasencia and Badajoz that was inaugurated on 18 July 2022 at an investment cost of €1.7 billion. It is a double Iberian gauge line that is due to be changed to standard gauge in the future. The total budget for the Madrid–Extremadura line is €3.7 billion^[65] and when the line is finished it is expected to provide high-speed rail services linking Badajoz to Madrid in 2 hours 31 minutes.^[106]

• Zaragoza–Castejon–Pamplona

A high-speed track between Zaragoza (Aragon) and Pamplona (Navarre) is currently under development as a part of the Two Seas (Cantabrian-Mediterranean) corridor. The section between Castejon and Pamplona (both in Navarre) with a total length of 75.5 kilometers is under construction with some sub-sections already completed.^[143] The line initially expected to be completed by 2023^[144] but new estimations give now 2027 as completion year. The 82.3 km section between Zaragoza and Castejón is in design phase with the second informative study publiced in 2023, while its completion is expected to take at least one more decade. The total budget for the Zaragoza–Pamplona line ranges from 1,252 to 1,446 million euros depending on the layout around Zaragoza and the planned station in Tudela, while travel time is expected to cut in half from two hours now to one hour in the new high-speed line.^[107]

In the short term, other connections to the LGV are planned. After the connection to France at La Jonquera in Catalonia, another connection is proposed at Irun in the Basque Country. Other new lines are under consideration, including a line connecting Soria to the Madrid–Barcelona line at Calatayud. Finally, the Madrid–Barcelona line currently terminates in Barcelona's Estació de Sants, but a new station is under construction at La Sagrera on the northern edge of the city.

In the long term, the Spanish government has an ambitious plan to make 7,000 kilometres (4,300 mi) of high-speed railway operational, with all provincial capitals at most only 4 hours from Madrid, and 6+1⁄2 hours from Barcelona. According to the Strategic Plan for railway infrastructures developed by the Spanish Ministerio de Fomento (Ministry of Public Works), called PEIT, and published in 2005, a second expansion program is planned to start when the last lines of the first program still under construction begin operation. This plan initially had a ten-year scope, ending in 2020, and its ambition was to make the 300 km/h (186 mph) network reach 10,000 kilometres (6,200 mi) by the end of that year.^[145] However, this program has been now postponed to indefinite time frame since the first expansion program is still on going. When both programs will be completed, the Spanish high-speed network will be the most extensive network in Europe, with several operational links with France and Portugal, and this is the most ambitious high-speed rail plan in the European Union.

In May 2021 the Spanish Ministry of Transport, Mobility and Urban Agenda announced its plans to connect Madrid's Adolfo Suárez Madrid–Barajas Airport with the high-speed network. According to the plans this is going to be realized in two phases. In the first short-term phase, AVE trains will reach the airport by sharing a line with the Cercanías trains until Chamartín station. Tendering for these works is planned to start within 2022. In long-term during the second phase, a dedicated high-speed line will be constructed to connect the airport.^[146]

• Galicia–Asturias–Cantabria–Basque Country–French border

The 430 km high-speed line will connect Ferrol in Galicia with Bilbao in the Basque Country passing through the regions of Asturias and Cantabria along the Cantabrian Sea coast in the north Spain. The line will be further connected to the Atlantic Axis high-speed rail line on the west, the Basque Y high-speed railway line on the east and the north corridor (Madrid–Asturias high-speed rail line) in Asturias region. The travel time between El Ferrol and Bilbao in the new line is estimated to last 1 hour and 48 minutes at average speeds of 250 km/h (155 mph).^[147] The line is not yet projected, although the initial plan was for completion before 2024.^[148]

• Valencian Community–Aragon–La Rioja–Navarre–Basque Country–French border

The line will connect the Valencian Community with the Basque Country region and the French border passing through the regions of Aragon, Navarre and La Rioja, with further connection to the TGV network via Irun towards Bordeaux and Paris. The line will include two connections between the region of Aragon and the Basque Country, one via Pamplona in Navarre towards the French border and one via Logroño in La Rioja towards Bilbao. Connected cities will include Valencia, Teruel, Zaragoza, Pamplona, Logroño, Vitoria-Gasteiz, San Sebastián and Bilbao with possible further connection to Santander. The travel time between Valencia and Bilbao in the new high-speed line will be decreased from 9 hours down to roughly 4 hours.^[149] Some sections between the regions of Aragon, Navarre and La Rioja are projected, while the section between Castejon and Pamplona is currently under construction.^[144] The Ministry of Development has not set a target date to complete the Cantabrian-Mediterranean corridor yet.^[143]

• Zaragoza–Huesca–French border–Toulouse

A new high-capacity rail connecting Spain with France on international standard gauge track is considered via a 40 km tunnel through the central Pyrenees mountains. The line, also called Trans-Pyrenean Central Corridor (Travesía Central de los Pirineos) or TCP project, will serve both passenger high-speed trains as well as large freight trains and will connect directly Zaragoza to Toulouse via Huesca a distance of 355 km in length.^[150][151] Ten possible alternatives are being considered for crossing the mountains, all of them including tunnels at low altitude and other possible stops include Tarbes or Pau. There is currently no clear provision on its construction.^[152]

The still-growing network transported a record 32.4 million passengers in 2023.^[153] Though the network length is extensive, it lags in ridership behind comparable high-speed rail systems in Japan, France, Germany, China, Taiwan, and Korea.
