    Hi,
    Do you know why the warning light "safety system isolated" comes on after 10 to 15 minutes of driving?
    Before starting, I activated all safety systems as shown in the image below

    Perhaps, it's due to neutral sections? It's a normal behaviour of safety systems IRL ? II thought the battery kept the security systems functioning.

    Probably a bug. See if you can reproduce it, then video it and report it.

    Best chance of getting someone to look at it.

    Also post it in the feedback thread and someone else might see it, or have a better answer.

    Yes, this must be a bug. I've managed to reproduce this by enabling the safety systems and then switching power modes. Specifically when operating the pantograph. So perhaps when it goes through a neutral section and the line volt light goes off and on again the safety system isolated light also illuminates again. That said, I didn't think that neutral sections were modelled in this route, but that's my best guess as to what's happening.

    In fact they are, at least partially...
    I've noticed the one just north of Wembley disappeared recently, but I'm pretty sure it was there before (I may be wrong).
    The one close to Leighton Buzzard only works on certain lines it seems.

    It has to be said that the Pendolino totally ignore neutral sections (the line light always stays on), seems it's the same for the 805 though I didn't really pay attention to it.
