ELR Track Locator Downloads & RevenueELR Track Locator · App Store

ELR Track Locator uses your phone's GPS to tell you your live ELR, track and mileage on the UK railway network — like reading a physical milepost, wherever you're standing.

For anyone who needs to know exactly where they are on the rail network. Your position and mileage are worked out on your device from Network Rail track data built into the app, so the core readings keep working with no phone signal — only the map background needs a connection to load.

No sign-up. No account. No login. Download it and it works.

Everything above is free, always. On top of it sits a Pro toolkit for capturing site detail and working with KMZ files. With Explore Mode, move the map and read the track ID and mileage anywhere on the network — scope out a site before you ever travel to it. Take photos on site that are watermarked with your photo label, ELR, mileage and grid reference — ready to drop straight into a report. Load your own KMZ overlays so site limits, plans and points of interest are drawn on the live map. And with Site Notes, record a whole walkout on your phone: drop named pins as you go, attach photos and measurements, then export the lot as a KMZ to open in Google Earth back at the office.
