Good to Know
Trackser is not intended for safety-critical decisions. Train formations and positions can change — always confirm details when on duty. Never use electronic devices while operating a train.
Still Evolving
Trackser continues to grow. More interactive maps, performance insights, and user-friendly tools are on the way. Feedback from staff and commuters helps shape every update.
If you have suggestions or run into any issues, you can reach out anytime — your input makes a big difference.
Ratings & Reviews
This app has not received enough ratings or reviews to display an overview.
- Metropolitan line map now includes the updated data for the new CBTC extension to Preston Road. Trains in this area should now be more accurate and report better such as destination and train numbers.
- Fixed bugs to do with some stats
- Fixed a few naughty trains and their positions on other line maps.
Please contact me with any feedback, positive or negative, I am keen to hear from you!
