The Class 4030 of the Austrian Federal Railways (ÖBB) were electric multiple units. In the narrower sense, 4030 was the designation of the railcars, the control cars were designated as series 6030 and the intermediate cars as series 7030. They were used in regional train services from 1956 and, with a few adaptations, were used as the first generation of Vienna express trains from 1962. Their use in scheduled services ended in 2004.

The first series of the 4030 series was built between 1956 and 1960. These trains, designated 4030.0, were originally 4-car units and intended for regional services. The 2nd series was intended for operation on the Vienna express line. When it became apparent that not enough 2nd series trains could be delivered before the opening in February 1962, the last four sets produced in the first series were adapted for rapid transit operation at short notice by installing a multiple control system and pneumatic door closing device and designated as the 4030.1 series. The 4030.1 and the 4030.2 delivered from 1961 to 75 were 3-part from the start. Later, the trains of the 1st series were also shortened to three cars. The designation was changed from 4030.0 to 4030.3 when they were retrofitted with a pneumatic door closing device and multiple control between 1969 and 1982. The surplus intermediate coaches were used as passenger coaches. This was possible without any problems as the couplings and transitions met the usual standards for passenger coaches.

From 1978, the ÖBB 4020 series multiple units were delivered as the 2nd generation of high-speed trains. At the beginning of 2000, all 72 class 4030 railcars were still in the ÖBB fleet, but the last sets were taken out of service at the end of 2004. They were taken out of service in connection with the delivery of the 4024 series commuter railcars.
