Voith bought from RLG (WLE subsidiary) two locomotives of type MaK G 1203 BB. This one with no. 98 80 0273 006-3 D-DWK was parked in Wuppertal-Oberbarmen on 30th of June 2007.
I am not sure if it is the former RLG 66 (MaK 1000804/1983) or former RLG 67 (Mak 1000809/1986) but due some hints I would bet on 66. Maybe one of you know it more exactly.
