An S-Bahn unit at Berlin Alexanderplatz on 21 May 2015. Although the S-Bahn and the electrified main lines share some stations, as well as infrastructure, the tracks for the two systems are completely separate [except in special locations and subject to electrical safeguards] as the two electrical supply systems are incompatible.
