Gotthard Route: System.IO.InvalidDataException: Player train original position not clear

[Roger Fischer]

I am reporting this as a new bug, as I have investigated a specific case.

In this case the path selected contains a reversal after the first (very short) segment. The activity the path was created for uses a single locomotive (pusher/banker). Thus it fits on the track. But a longer train will not fit.

A potential solution is to do a more thorough path check in the Menu, and reject paths (from/to) that have a reversal within the length of the consist.

In the Menu:

Route: Gotthard Route
Activity: Explore
Locomotive: Any
Consist: 0111 - Flirt 2 Einheiten
Starting at: Erstfeld
Heading to: Göschenen

From the log file:

Mode = explorer
Route = Gotthard Route
Path = GTHD1_Zug14_Schiebedienst (C:\Games\Open Rails Content\PrevMSTSandSOBandPotash\ROUTES\gotthard_linie\PATHS\gthd1_zug14_schiebedienst.pat)

Weather = Clear (0)

It would also be reasonable to show the user an error dialog, and let the user resume with the Menu (and pick another path).

But I believe there currently is not mechanism to show error diaglogs (and exit).
