From: OP It is not possible to decouple long trains from the driver stand.
This is the screen when trying to do it: https://li-fo.de/long-train1
In this case it was possible to decouple manually with hitting the
coupling, but if that is locked then I see no way to do anything.
From: Developer couple locks do no longer exist.
this is an issue by design and would require a bit of work
