Hi, how can I get the class 37 to move while connected to class 700. Evertime I try it's like there's a handbrake on the 700. I've tried turning of the battery and so many other stuff. (On/off) but no use. The 37 keeps wheels limping because 700 wont move. Please help
In short it doesn’t. You can move it with the 37 but only at low speed. As soon as you brake the brakes lock on the unit. Here’s the thread https://forums.dovetailgames.com/threads/rail-operations-group-37.74673/
In reality you would either need barrier vehicles at both ends of the unit or an adapter coupling on the loco. The latter are generally only intended as a last resort to clear the line at dead slow speed after a catastrophic failure, if another Class 700 cannot assist (fault transmits to the coupled unit) or a fitter cannot rectify on site.
