Trackser – Real-Time London Underground Train Tracking

Version 7 is here. And it's properly different.

Trackser now runs on Trackser Live - our own custom server, built on richer TrackerNet data. All 11 lines are merged, cleansed and enriched on our servers. Your iPhone just reads the answer. Less data. Better battery. More detail than ever.

A NEW BACKEND. SAME PHONE, LESS OF IT. The heavy lifting - merging the raw feeds, inferring direction, detecting stalls, matching the timetable - now happens server-side and arrives as clean, compact data. Your phone stops doing the maths and just shows you trains.

EVERY TRAIN. ALL 11 LINES. Live positions on real track layouts - platforms, junctions, and the one crawling out of Baker Street. Every Tube line has full live map coverage, updated every minute.

DEPARTURES THAT ADMIT THE TRUTH. Live or timetabled, clearly labelled, per platform, for every station on the network - Tube, Overground, Elizabeth line, DLR, Tram and River. If a train has stalled, you'll see it. No wishful thinking.

DISRUPTION, IN PLAIN ENGLISH. AI-parsed service status with the full history and what's planned next - clear, readable and ready to act on. What's happening now, what happened earlier, and which closures are coming up.

BOOKED VERSUS ACTUAL. Metropolitan line timetables show booked stopping patterns, platforms and real destinations - every branch, minute by minute - set against what the train actually did. (Beta.)

NOT JUST A TRIP NUMBER. A UNIT. Leading car numbers, refurbished-train flags, and every run of the new Piccadilly 2024 Stock, logged automatically as it enters service. Trackser is probably the most detailed consumer-facing window into the Tube's day-to-day operation. We'll take that as a compliment. (Beta.)

WHO IT'S FOR Commuters - know if that train is actually coming, or just wishful thinking. Transport enthusiasts - unit numbers, refurb flags, stopping patterns and journey history in one place. Train operators - the original use case, still here: find your next pick-up and track movement across the network.

ALWAYS FREE. ALWAYS. Everything you see here is free. No login. No subscription. No faff. And that won't change - the live features you use today will always be free.

Coming later: Trackser Pulse, our own independent read on how the service is really running, and an optional Pro subscription for deep historical data and replay. The everyday app stays free.
