VRR-Infoscreen shows the next departures at a public transit stop, just like the Lumino LED displays used in some places. It also supports an app / infoscreen-like frontend (click/tap on a departure for details) and JSON export.

It works best for the VRR (Verkehrsverbund Rhein-Ruhr), but also supports many other german transit networks. All information is provided without any guarantee of correctness, completeness or anything else.
