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?
You need a way with 2..n nodes (one for each layer) which are almost on top of each other. This will mean that the lift will be routable.
