The HŽ series 6111 is an electric multiple unit used by Croatian Railways (Croatian: hrvatske željeznice, HŽ), formerly the class JŽ 411 of ŽTP Zagreb during the period of Yugoslav Railways. The vehicles were built by Ganz Mávag, Hungary (production started in 1976).^[1] Most of the sets were later modernized by TŽV Gredelj between 2002 and 2015, including both interior and exterior modifications. They are popularly nicknamed Mađar (Hungarian) in reference to their country of origin.

The 6111 series EMUs are made of three cars: 4111 and 5111 unpowered cab cars that differ in types of electrical components contained, and the middle 6111 car that provides power to the trainset. The power car supplies power to the motors using a thyristor rectifier. The trains can be operated in sets of up to three units.^[2]

Between 1992 and the mid-2010s, the principal purpose of the units was to serve Zagreb Commuter Rail where they operated exclusively, in addition to some other electrified lines in short to medium distance from Zagreb. Between 2011 and 2023 the units have been fully replaced with the HŽ 6112 series on Zagreb suburban lines, so remaining 6111 sets were mostly returned to serve regional routes across the country.

Following the replacement of the electric traction system in the section Moravice - Rijeka - Šapjane (border with Slovenia) from 3 kV DC to 25 kV 50 Hz in 2012, the 6111 series was given the opportunity to operate on the lines between Zagreb and Rijeka, as well as suburban services from Rijeka.^[3]

Over the years, HŽ 6111 series units have had various modifications done, including the replacement of sliding side windows for tilting windows and the addition of exterior destination displays on the sides. Some units have had a more extensive modernization including the addition of a new exterior destination display on the front and interior renewal including new seats.^[4]

The 6111 series units are being gradually replaced with the 6112 series trains, although no set timeframe has been provided about their definite retirement.

A meter gauge version of this trainset was also produced for use on the Sahel Metro in Tunisia; these units were known as YZ-E sets. The trains have been retired in 2010 and replaced by newly-built Hyundai Rotem units.
