History edit
The units were commissioned by Deutsche Bahn in 2005. 78 units worth €343 million were built by Bombardier Transportation and Alstom and delivered between March 2008 and October 2010. They are now used in such places as like on the Rhine-Ruhr S-Bahn which operate in cities like Köln and Düsseldorf as well as the Ruhr area.
Deutsche Bahn uses the units on the Rhine-Ruhr S-Bahn network, unlike most S-Bahn Networks which use similar DBAG Class 423 trains. The inner carriages are called Class 432. Following a timetable change in December of 2019 the units are currently used exclusively on the S1, S4, S5 and S6 lines of the network.
