First of all, no, I don't know if this is a bug or if it's wanted, I just don't know. (I use the ps5 version) So what do we see right there because ge 4/4 and then abe 8/12 I actually wanted to use ab8/12 as a test on the arosa line, but somehow it can't be driven as well as with the ge. If I now take an ice or the 628 as an example, they can be used (for whatever reason) the arosa line as well as on Berninal line, which makes even less sense.
The ge won't work in free roam because the power systems are incompatible irl. You have to use off the rails mode through scenario planner For the allegra, did you make sure to switch to ac power? I think the manual should cover it which I've not read through but you have to switch the power source. The 628 obviously works because it's diesel, not electric. The ice probably has compatible power
Not a bug, at least i hope . The arosa - chur line is using the stammnetz AC, so your GE4/4 from the dlc wont run in tirano. Same for the Allegra, you seem to use the Direct Current pantographs, which are used on the bernina line. Change the Power system to AC on the allegra and it should work.
Ok Wait the abe 8/12 have which current ok I didn't know that but I can try right away thank you (and yes true 628 is a diesel car I forgot that)
There should be a switch on the right side that lets you choose power. The manual doesn't go through the procedure, but it should tell you where the switch is https://cdn.akamai.steamstatic.com/...rnina-Tirano_Manual-PC_EN_v4.pdf?t=1705428033
