The last official number of "18 201" was "088 182-1". This number was valid from 1992 on. But it was never intended to be writen onto the locomotive. "×88"-series numbers were always intended for internal use only.
Those red filter slides are typically West German equipment. They were not used in GDR. And it's very improbable, that accomodations for them have been installed onto East German railroad vehicles after the fall of the Berlin Wall.j p wrote:They had red filter slides instead - which could make red marker lights out of the white ones. The diesels from 1950s which we have in the train club have the same solution, only Köf has separate red bulbs.
East German locomotives without separate red marker lights have always used the same EOT devices, also used with freight cars.
And here some images of the prototype:
I took these photos in Guben when "18 201" went to Poland for the very first time on April 28, 2007.
