Route searching problem

[ronnie89b]

Hello!
I found a bug in the route searching system. I know the passengers always prefer the routes with less transfers, but in my map they sometimes doesn't.
The situatiom: line 1 is a long line between two big city with a lot of travellers.  Then I add a new station for my train line(29) and something goes wrong. The passengers don't choose the direct line, they go with the train and a bus (line 2).
See line 1's first stop, there are 10000 passenger to the last city and they don't chose the corract route. Then  delete some stops from line 1, or  delete the trains, or add a bus to line 1E, the problem disappear.

I use stable 112.3, pak 128 with vehicles from the compatibility pack.
