In the scenario planner, TVL I created a scenario form Darlington to Red care Mineral terminal. Consist is 2x Cl37 + 24 empty coal hoppers. The driver starts in the cab facing the second locomotive, instead of the front cab. Cab 2 is placed at the front (this is OK, but this may have caused the problem). You can see this at the enclosed 2D map. It is not a big issue, but it is sloppy. I think more care is needed for these details.
