I loaded the save in 0.15.7, and the crash does not occur anymore.

I've encountered this bug after playing on an old map for a while.
The map played fine in releases 0.15.1 through at least 0.15.4.

There is a train in one of the stations, as soon as one of the carriages (the first from the right in the savegame provided) moves over a certain tile, the game crashes ...
