Train is running on time.
Train is delayed 0 to 5 minutes.
Train is delayed 5 to 15 minutes.
Train is delayed by more than 15 minutes.
When the cluster map button is toggled on, trains in close proximity are represented by a marker cluster that is coloured according to the average delay of the trains belonging to that cluster.
How it works
This map shows the real-time locations of all passenger trains in Great Britain.
The positions are provided by Signalbox API, which uses a proprietary machine-learning algorithm to estimate the real-time location of each train. Train locations are computed using multiple information sources, including train timetable data, signalling information, real-time train arrival and departure times, map-data, crowd-sourced movement data and train GPS data (when available).
The train locations shown on the map are typically accurate to a few hundred metres.
However, more accurate locations, updated more frequently, are available directly from our API. For access to these locations, please sign up to our API here.
If trains are not displaying or updating, try refreshing the page. Also, make sure you have a good internet connection.
This map has been tested on a number of different devices and browsers and performs well in the vast majority of cases. However, some older devices may have trouble showing and subsequently updating the trains.
