As shown in the attached screenshots, toggling layer visibility results in obscuring the contents of train carriages, the contents of train loaders and unloaders, and moving parts of the loader and unloader models (the little door which hinges up and the loading ramp which hinges down) in a way which doesn't accord with the function of layer visibility on platforms. I.e. turning on layer visibility:
- with the bottom layer selected hides all these things except the flip-down ramps on the bottom layer;
- with the middle layer selected shows all these things on the bottom layer, but not the middle layer; and
- with the top layer selected shows all these things on the bottom layer, plus the flip-down ramps on the middle layer, but nothing on the top layer.
Expected behaviour is that either layer visibility works on trains and their loaders and unloaders like it does on platforms, or it has no effect on how train-related stuff is displayed.
