This is really cool, but I wonder why the UK rail (commuter or long distance) network isn't shown very completely. There are _lots_ more trains around Birmingham or up north that don't get displayed. Even the network in the SE is very partial. Is this data really not in OSM?

They discuss in the paper that those routes are less trivial to query. For that reason, and I guess to mimic the traditional local transit maps the online version only queries routes with the `route` key `light_rail`, `tram` or `subway`.
