Two interesting locos photographed in Aachen West on 16 October 2001 (from the end of the platform, no chance to get closer). On the right is one of the two diesel locos of the Dürener Kreisbahn (DKB), but it is not possible to determine which one. I've never seen DKB locos in Aachen before. On the left is something in the old orange DR livery, I do not know which operator it belongs to. I guess both locos are there to operate work trains, there is a crane behind the DKB loco.
