DB Class 218 Diesel Locomotive.
218 428-1 with train RE31435 (16:10 to Mühldorf) in platform 6 at München Hauptbahnhof on Sunday September 22nd, 2002. 218 416-6 was on the other end of the double deck coaches and there was no Steuerwagen. According to Internet loco diagrams this train is usually worked by a single 218, so it was probably strengthened for the Octoberfest weekend.
