I would like to see the Innerstetalbahn in the year 1966 in TSW https://de.wikipedia.org/wiki/Bahnstrecke_Langelsheim%E2%80%93Altenau_(Oberharz) with the DB Baureihe 50 https://de.wikipedia.org/wiki/DR-Baureihe_50 and the DB Baureihe VT 98 https://de.wikipedia.org/wiki/DB-Baureihe_VT_98 there where Cargo trains to Lautenthal, Frankscharrenhütte and Clausthal-Zellerfeld and when there was lots of Snow the passenger trains where also with steam engines. I think it’s a good idea because there is a beutiful landscape in the region and it world be the first German route with steam locos Running on it in TSW. Baureihe 50 in Altenau:
