I know off the rails mode allows even locos that use 3 rail power or over headlines to operate on lines without them but the tgv 200 just doesn't want to go at all.So just what needed to make it work or is it just not possible.Compared to other overhead and 3 rail trains the overly complicated control setup is most likely part of the problem using this train in off the rails mode.
I think you just set it up the same way you would on the LGV route. Service retention button Pressed Master Switch to On Power mode Selector as desired Pantograph to Normal Circuit breaker Switch Circuit breaker Arm switch Reverser Forward Driving Mode Select
