The Real-Time Train Map

The Signalbox Live Train Map shows the location of trains in the UK in real-time on an interactive map. Zoom-in on the Live Train Map and you can watch the trains actually moving on the map to show the trains' real-time, real world locations. 

Trains on the map are indicated by colored arrows. The arrows show the direction of travel of the train and the color indicates whether the train is delayed or running on time (green = on time, yellow = 1-10 min delay, & red = over 10 min delay). Click on an individual train marker and you can lock onto that train to track it as it moves on the map. If you select the 'view stops' option you can also see a train's entire schedule and when it is timetabled to arrive at each station on its route.

The Signalbox Live Train Map also includes a number of filtering tools. These allow you to filter the map to show only trains from a specific train company or to only show trains traveling to or from a named station.
