Omnicom's Track Locator provides those working on, or interested in, the UK Rail Industry with a simple way to determine their current location in the standard rail referencing system of Engineering Line Reference and Mileage. The application uses the iPhone Location Service and converts this to a railway reference using Omnicom's GeoModel of the rail network.

The App links to iOS Maps to show the current location on a scalable map.

The App allows the user to take a picture which is stamped with the current user location including Latitude, Longitude (of the current location) and map matched ELR, Mileage, Latitude, Longitude as well as the user location to matched position difference. The images are saved to the Camera Roll for easy access.

The rail reference is only displayed once a suitable location determination has been achieved. This is currently set at better than 100m. Please note that due to the accuracy of the iOS Location Services correct determination of Track Identifier may not be achieved.

Notice to user of the current version.

A number of you have noted that the Track ID functionality (up/down/fast/slow etc) was removed in a previous update and that you would like this reinstated. Track ID was removed as a direct result of misuse of the App by a user. Despite clear instructions that the location information was not to be relied upon, it was, and could have led to a serious incident. Network Rail requested that this function be removed from the App and we complied with this request.

Users are reminded that the locational accuracy of GPS in mobile devices can vary widely due to a number of factors and should not be used when making decisions with safety implications.

iOS 11 Upgrade Required


I’m running iOS 11.2.5 and all I now get from the app is poor gps, meaning it won’t provide a railway mileage. Shows my position on the map correctly however. Real shame as it is a great app that I used all the time. Any chance of an update? It did originally work on iOS 11, it just seems to be one of the recent smaller updates that has broken it.



Like the user above, I feel it’s a real shame that this useful app for railway workers & enthusiasts alike has become useless thanks to the current IOS 11 version. Please update so we can all continue to use this app!

Won’t work

I use this on a regular basis and it simply stopped working. Very disappointed
