About

This extension adds OpenStreetMap based functionality to the Realtime Trains website (http://www.realtimetrains.co.uk/).

Features:
- Visualises the route taken by a train on a map
- (Part) cancelled routes are shown in grey
- The last known position of a train is displayed as a marker (if available)
- Route length can be seen by clicking the 'info' button in the bottom right corner of the map

New in version 0.6.0:
- Updated to Manifest v3
- Added display of public calls (circles) and non-public calls (triangles)
- Bit of data cleansing for some obscure routing points

Please note that this extension is not developed by the makers of Realtime Trains and is not affiliated with swlines ltd.
