problems with signals

[Wolf01]

if i try to build a 2 way railroad with terminus stations like TTD appear continuously "(name of the train) couldn't find route", and when entering a station trains don't select the free platform

In Simutrans route is platform specific - trains always use the same platform. Using RoRo stations is usualy best way . And if it says it cant find route it is always true - check if there arent any gaps bettwen tracks, and is the track electrified if you use eletric trains.

Possibilites of can't find route are
-broken tracks
-opposite signals on a one way track (for example, a track is for going to the station, but the signal is placed for coming.
-(I tried the latest version, and I found that when you build tunnes below the normal ground level (altitude of 1), then the same message is shown
