Overview of the SGP 4020

Explore the ÖBB 4020 series, an iconic Austrian electric multiple unit (EMU) that has been a staple on Austrian railways since the late 1970s. Built by SGP between 1978 and 1987, these versatile trains were designed for efficient passenger transport.

With a seating capacity of 184 passengers and a top speed of 120 km/h, the ÖBB 4020 series is powered by a robust 1200 kW electric system, operating on 15 kV AC 16.7 Hz. Their standard gauge of 1435 mm and a three-car formation (1M) make them a familiar sight across Austria.
