One of the two diesel locos of the Dürener Kreisbahn (DKB) seen in Düren on 25 September 2001. Note that it also has an inscription of the track working company Kölngleis. As it is often to be seen at the construction works on the main line to Cologne, it seems likely that it is hired by Kölngleis. Even in the moment of the photo the parked loco is coupled to a train of hopper cars, which are used to transport ballast to the construction site.
