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.

¹ separate values with commas, e.g. NE,U,10

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
