Here is another function which the game engine can handle but the FMB does not. Switching trains across sidings. Again you can do this by manually editing the *.mis file. Train scheduling is fun

. Try and avoid collisions. Maybe this could be enabled in the FMB?
The scene is in the central dock area of the NW Europe map. Here is some text to paste into a mis file to enable the scene. You also need to set up a static camera. Three trains are running on the same track, but each train is switched to a siding to enable them all to enter the unloading area. Similar system could be used to allow trains to pass each other where there is a passing loop at an intermediate train station.

The rail network is roughly on a 5m grid so you can zoom in on the FMB map and make a note of the coords for each corner.
Unlike ship waypoints, if you load this back into FMB the manual edits will be lost. FMB will just read the first two waypoints ignore the rest, so keep a backup of the train text.
