iRail planner

A JavaScript route planning library for browsers and Node.js, built specifically for Belgium and adaptable to your own data and routing needs. It reads Linked Connections 2.0-alpha Arrow data and calculates routes locally.

  • Journey alternatives across multiple networks, with walking transfers.
  • Isochrones showing which stops can be reached within a time limit.
  • Station or coordinate-based routing, including walking to and from stops.

The current alpha uses scheduled timetables. Its playground includes a route planner, isochrone maps, and library documentation, and lets you load your own timetable.
