A MaK diesel electric test locomotive was used for some trials on the 13th January 1983. The photo was taken in the OHE depot Celle Nord. Evidently the OHE didn't like this type of locomotives, as the next locomotives bought by the OHE had the standard propilsion again. (Sorry for the bad picture quality, but the weather was terrible and better photos are not known to me).
