That feature is not (yet?) implemented. For the moment Train Fever will work with only fixed paths. The system’s path finding will decide what it thinks is the best route. You have no direct control over it. Waypoints, to force a certain route, are announced, but alternative paths upon track occupation (eg in stations with occupide platforms) are not (yet?).
For the moment you can’t use multiple platforms for one single line, except in the case of the returning route of the same line. You can split opposite traffic with one way signals.
