Sounds good. How about the following:- A railway=stop node for the point on the track where the front of the train should stop. Using railway=platform (linear way) for each platform (parallel to the track) Then a platform=boarding_point node for each car-stop sign on the platform way with the carriage number - possibly multiple ones per platform We then have enough information for people to play trains! If the station has multiple levels then each element should have a layer tag and we will need to consider how one manages a single level (concourse) where one side has a level entrance to the outside world layer=0? and the other side is up a load of steps to the concourse and could be considered layer=1 I guess we just choose a set of layers we will use and then join them to the outside world with a 'footway' or with 'steps' For a lift we use a node with multiple layer numbers highway=lift? layer=0,1,2? I have been trying to capture most of this on the Stop Area proposal - not so much a proposal as a description of good practice:- http://wiki.openstreetmap.org/wiki/Proposed_features/Stop_Area Regards, Peter > > 2009/9/18 Peter Childs <pchi...@bcs.org>: >> 2009/9/18 Frankie Roberto <fran...@frankieroberto.com>: >>> >>> 2009/9/18 Peter Childs <pchi...@bcs.org> >>> >>>> Its very difficult as London Bridge is based on about 6 layers with >>>> random escalators, lifts and ramps connecting it up. >>>> >>>> I'm thinking the building should only cover parts with a roof on >>>> and >>>> hence really needs cutting up..... >>> >>> Yeah, agree. >>> >>>> >>>> Is there a marker I can put up to say where the trains actually >>>> stop >>>> and that you need to move down the platform. >>> >>> Ideally, there should a way per railway track, and a way per >>> platform (you >>> can map platforms as areas, but it seems to work better as linear >>> ways).
