1) Would it make sense to seek permision from TfL to derive labelling information from their website maps. It's such a rich source of info, it'd be a pity not to try. They're a bit daft putting copyright on their spider diagrams - if I were them, I'd want them to be copied.
2) I don't like the idea of ways for platforms, except possibly for the limited case where you've got one platform on each side. It's just not extendable. They should be areas. Sublettering for parts of platforms should probably be on nodes, representing the point on the platform that's the midpoint for boarding a train that stops at that platform (it will be in the timetable system as "2a", and a notional router ought to direct you to that point). If a platform is split into 2a and 2b, you probably need three nodes - 2a/2b and 2 (for trains that take up the full length).
