VRR-Infoscreen shows the next departures at a public transit stop, just like
the Lumino LED displays used at some stops.
It works best for the VRR (Verkehrsverbund Rhein-Ruhr), but also supports most
other German transit networks.

notes:
- The EFA backend does not support Umlauts
- For Düsseldorf, the DB backend usually gives better results
- If you write the city correctly (like "Essen", not "essen"), vrr-infoscreen can
shorten destination names
- Example
- See also db-infoscreen for an
interface optimized for Deutsche Bahn departure data
