After i deleted a station entry from the schedule and set a new point on it, the crash happened when i closed the schedule dialogue.

Hunch: the crash might be related to the "reverse schedule code".

Background: i had some problems running a heavier train on the route used successfully before. the was able to drive directly in front of the station, but could not find route for the next step. For the heavier train i had to replace rails over large stretches gaps were not unlikely. The train was also longer than the trains before, i had to remove a signal and increase the platform length. (might be relevant for reverse schedule tests). The previous waypoint was before set on the other direction platform, it could only be reached by a large detour.

SDog,

thank you for the report. Can you upload a saved game and let me know precisely which line that you amended and in what way so that I can reproduce the circumstances of this crash exactly?

[sdog]

since the circumstances leading to the crash were rather complex, it might be difficult to recreat them. As soon as i get something in that direction, i'll provide a save game. (the most recent save before i had before the crash is roughly the same as the 141.sve from the other thread, i upgraded the express route for line 62)
