E52, E04-01/BR244, E91, E97 and what I forgot. here some of the missing ones part1: youtube.com/watch?v=RZpLSAUe0i4 Part2: youtube.com/watch?v=Y8cTaKsLnag Munich and around there, they had a lot of the old locos in work till the 1970s. Easy technique.
They create locos after the time of the Altbau E-Locos. E18 is the only old one from the 30s years time. All the others are beauties from the 50s-2000s. Since a time they produced not new content. The product better, they didn’t make too. That’s sad. Because some bugs and patches would be possible and good for sell the product in better quality.
In the east of Germany, there it is possible to ask one of the train clubs, to get in an old loco. But some old locos are not in service able anymore. They would be need a refresh service, for can go 8 years again on the track, for special services and events.
I thought it was a 251. I would love an E42/242 as it is easily renumbered to E11 and 109 (as in the real world Dessau).
Bring them in and the thing with some of these locomotives they're also found in East Germany as 244 & 254. For American Railway troops in West Germany DR Baureihe 244 & 254 Kriegselok is called as DB Baureihe 144 & 194 Krokodil the latter having enough tractive force to climb Gelsinger Stiege & Alte Spessart Rampe Laufach Heigenbrücken.
At the moment is not much movement by DTG for Germany loco and track material. I wish a not so long waiting for new content. So much potential this TSC bet still happen.
