S-Bahn Hamburg ordered 60 of the three-car trains from Bombardier in June 2013 in a €327m deal which includes four dual-voltage sets capable of operating on both 1.2kV dc S-Bahn network and the standard German 15kV 16.7Hz system.

The first eight trains, including two of the dual-voltage sets, will be delivered for trials at the end of 2016 and the entire fleet is due to enter service by the end of 2018. This will enable the withdrawal of the fleet of class 472 trains, which date from the early 1980s.
