Doing the track layout within the station is something I am sure that railway people will want to do - indeed they won't be able to resist doing it :) Do lets get the separation of the track true-to-life though. With regard to long sections of parallel track between stations I suggest the 'lanes' tag could be suitable, if not then the parallel tracks would need to be placed the correct physical distance apart and then the renderers would need to be able to simplify the presentation down to a single line for wider area maps and do two track far enough apart so that they can be distinguished from each other for close up maps. Sounds like we are going to need to 'suck it and see'. Possibly we should go for the most detailed representation on the ground and then use relations to associate elements together to help the renderer.
