locationSearch uses mgate.exe, just like the regular departure board.
similar_stops_p relies on ajax-getstop.exe which may become unavailable sooner

In some cases (e.g. in Belgium), trains do not have a type, so the first part
of $train->line is the train number instead.

(preparations for more flexible checkin time frames)

Still TODO: handle stations that have several EVAs
