The Class 4030 of the Austrian Federal Railways (ÖBB) were electric multiple units.

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.

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.
