The train made a short return trip from Wiener Neustadt to Lanzenkirchen on the non-electrified line to Aspang, reaching speeds of up to 120km/h in battery mode. The three-car set, which has been branded Cityjet eco by ÖBB, was converted from a standard class 4746 EMU (No.4746 049) and first unveiled in September 2018. Batteries and control equipment are mounted on the roof of the intermediate trailer car. ÖBB hopes to use battery trains on short branch lines where electrification is considered uneconomic. Charging can take place at the terminus station from the national grid as well as from the catenary on electrified sections. The train will be tested in passenger operation in the second half of this year.
