The East German electric locomotives of DR Class E 251 (from 1970: 251, DBAG Class 171) were not standard engines either within the Deutsche Reichsbahn's or subsequently the Deutsche Bahn's fleet, due to the different specification of their electrical system. They were only used on the Blankenburg (Harz) – Königshütte (Rübeland Railway) line. Because this line had steep inclines, but connecting this isolated branch to the main traction network would have been very expensive, the Deutsche Reichsbahn electrified it in 1965 with a 25 kV 50 Hz system, which was different from the usual German catenary supply of 15 kV 16⅔ Hz. The 15 Co’Co’ engines were supplied by LEW and registered with the Reichsbahn as E 251 001 to 015. More: https://de.wikipedia.org/wiki/DR-Baureihe_E_251 And yes! There is a DB Cargo livery, since it's what most German locomotives have been given in TSW but don't forget to check out the link as other variants were present. What one would make sense the most? With 12 axles and 124 tons you will get a workout! A 2019 video will show you this heavyweight beast in more detail
