DB Class 472

The DB Class 472/473 is a three-car electric multiple unit train for the Hamburg S-Bahn. They were built to service the new lines through the city tunnel (opened 1975), to Harburg (opened 1983) and to Neugraben (opened 1984). The livery was beige blue at first, but it was changed to verkehrsrot (traffic-red) in 1997.[1] The Class 473 is the centre carriage of the Class 472, it differs from the predecessor (470 and 471) centre carriages in its own electric motors and they have three door pairs instead of four.
