being extended from its current terminus at Neugraben, south of
Hamburg, to Stade, east of the city. On the Hamburg S-Bahn
network, the 1.2 kV DC power supply is by third rail, while
on the extension, overhead lines will supply the trains the
15 kV AC via the trains’ pantographs.

For this reason, the trains to be renovated and the new trains
will be equipped to operate under both types of power supply. The
