Code Issues

(svn r18382) -Codechange: make road vehicles behave more like trains 'around' stations and use pathfinder penalties to determine to which 'part' to go. Note that the pathfinder penalties for drive through stops are currently only looking at the occupation of the first in a row, but this is to change later on.
