Yeah Thai1on , I have a habit of pushing back through junctions after stopping the driver, meanwhile the junctions have changed back and I did not save because it takes ages ..start over again.
Thanks oknotzen, I will have a look on the DLS for those vehicles, but I am still learning about the DLS and to find my way.
I was thinking of an operational depot and equipment like the cranes used in the woodyards in the sessions to make it interesting , that one could despatch that will 'fix' the derailments on the scenes, like lifting the trucks and locomotives and rerailing them. Not sure if it can be done, a lot of work if it could - i'm sure.
