working:
* checkin
* checkout
* realtime data
* polylines

* geolocation
* redirects after checkout / undo
* traewelling sync
* use dbris by default

Luckily, ÖBB and IRIS agree on virtually all EVA IDs. In some cases, ÖBB
uses different station names (e.g. 'Fürth in Bayern' rather than 'Fürth(Bay)').
