Platform assignments without the radio.

Tracks are a constraint. relay solves them. Inbound services are matched to the right platform by length, electrification, occupancy, and turnaround. Conflicts are flagged before they happen. Operators see one map. Passengers see one number.

  • ConstraintsLength, gauge, voltage, platform height
  • ConflictsDetected up to 90 minutes ahead
  • ReassignOne click, broadcast in 200ms
  • FailoverManual override, always available
03 · API

Real-time data. Plain JSON.

Every departure, every arrival, every status change flows through one endpoint. Subscribe over WebSocket or poll over HTTP. No proprietary feed format. No dialect. Just the schedule, in the open.
