TfL supplies its data to NaPTAN - and this is the national official source of stop names. I would therefore ask that OSM focuses on using the official source of data - and reports discrepancies which I can then take up with the responsible people in TfL

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).

I have added those extra details to a few stations, in some cases even adding the platform numbers. It does become more difficult when there are island platforms. The reason why I have been adding them is from a desire to know how to access the station, and how to access the platforms. It is also an increased detail thing. I had a discussion about island platforms on the wiki a while back (see http://wiki.openstreetmap.org/wiki/Talk:Proposed_features/unified_stoparea#S heffield). When I mapped Sheffield Station (http://www.openstreetmap.org/?relation=79249) I noted that some platforms have up to 6 different names (2A, 2B, 3, 4, 5A, 5B). The options as I see it are: * stick all the names in a single ref= tag, semi-colon or comma separated (the former seems to be the convention?) * add the names to the stopping points (the node on the actual railway way). * splitting the platform way into different ways (eg two halves) and then tagging those separately (although this still leaves you the problem of different names for the different 'edges'). * doing something complicated with relations.
