Data is cached for 1 minute. JSON format:

error: err string if an error occured, otherwise null
preformatted: strings used by the PNG / HTML frontend
raw: % if (param('backend') and param('backend') eq 'db') { serialized Travel::Status::DE::DeutscheBahn-objects, see the ::Result documentation % } % elsif (param('backend') and param('backend') eq 'aseag') { serialized Travel::Status::DE::URA-objects, see the ::Result documentation % } % else { serialized Travel::Status::DE::VRR-objects, see the ::Result and ::Line documentation % }

NOTE: The JSON interface is not guaranteed to be stable. The data layout may change any time.

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
