The ÖBB 4030 is a 3-car electric multiple unit used by the ÖBB for regional rail passenger transport, especially on the Vienna S-Bahn. A derived variant ÖBB 4130 with increased power allowing speeds up to 130 km/h (81 mph) was operated on the Transalpin international rail connection between Wien Westbahnhof and Basel SBB. From 1979 onwards the 4030 was gradually replaced by the ÖBB 4020, the last trains were retired in 2004.
