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.
</p>
<p>
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.
