I have a question, with the BR 155 locomotive, the red Lock Traction icon is constantly lit in the mini HUD, even though the locomotive can be accelerated normally. Is this some bug within TSW4? I tried the Salzburg - Rosenheim map and the Introduction to BR 155 and the Bremen - Oldenburg map and it's still the same. I also have an additional red BR155 for the Ruhr - Sieg, it is the same for both versions. Thank You.
The indicator is simply broken and not just on the 155 but on most locos from what I saw. Best to turn it off in the settings.
