Live line map on Track live
Track live now draws a simple line map of your train's calling points, with a service-coloured dot that creeps along to roughly where the train should be now.
What changed
The Track live page gained a simple line-map diagram above the route list. It lays out the service's calling points end to end, like an in-carriage line diagram, and shows a dot in the operator's brand colour travelling along the path. The dot's position is interpolated from the timetable—it sits between the last departed and next expected stop, and creeps forward smoothly between refreshes using the elapsed clock time. The completed part of the line fills in behind it, the current stop is emphasised, and cancelled services dim the line. The view scrolls to keep the dot centred on longer routes.
Why it matters
A glance at the map tells you roughly where your train is along its journey without reading the full list of times. It turns the time-based position estimate into something you can see at a glance, including how far it still has to go.
Who benefits
Anyone tracking a live UK National Rail service—c2c passengers along the Fenchurch Street to Shoeburyness line and travellers on every other operator alike, since the map is built from each service's own calling points.

Technical details
The map reuses the existing tracked-service route and timetable times—no new data feeds or station coordinates. Position is interpolated by scheduled segment times, with a constant average-speed fallback for segments the feed did not time, and is advanced client-side from the elapsed time since the data was generated so it never depends on the viewer's timezone. The service colour comes from the existing operator-colour mapping.
