TL;DR
A developer has launched a project that visualizes London train movements in 3D using deck.gl, TFL, and National Rail data. This allows users to track trains in real-time with high accuracy. The project is currently in a prototype stage and is accessible via a web interface.
A developer has launched a web-based 3D train tracker for London, leveraging the deck.gl library to visualize real-time train movements using data from Transport for London (TFL) and National Rail. The project aims to provide a more immersive and accurate way for users to follow train locations across the city and to nearby airports.
The visualization platform allows users to select any train from a given platform and see its real-time position in a 3D map. It integrates data feeds from the TFL API and National Rail, with minimal drift, meaning the train positions stay accurate over time. The developer, posting on Show HN, describes the tool as a prototype designed to enhance public transit tracking and potentially improve user experience for commuters and travelers.
The project uses deck.gl, a JavaScript library optimized for large-scale geospatial visualizations, to render dynamic, animated 3D models of trains moving along their routes. Users can pick a train from any platform, and the visualization updates in real-time, showing the train’s progress along its line. The developer emphasizes that the system can track trains to the nearest airports, offering a comprehensive view of transit connectivity in London.
While the project is currently in a developmental phase, it has garnered attention for its innovative approach to transit visualization and its potential to be integrated into existing apps or used as a standalone tool for train enthusiasts and commuters.
Potential Impact on London Transit Tracking
This project introduces a more immersive way for London commuters and travelers to understand train movements, potentially reducing confusion and improving transit planning. If adopted widely, it could enhance real-time tracking accuracy and user engagement with public transit data, fostering greater transparency and trust in transit services.
Moreover, the use of advanced visualization tools like deck.gl demonstrates how modern web technologies can improve accessibility to complex transit data, possibly influencing future transit app development in other cities.

London Transit Data and Visualization Technologies
London’s transit network is among the busiest in the world, with extensive data feeds from TFL and National Rail providing real-time train positions. Existing apps typically show static or 2D maps, which can be limited in conveying the movement and proximity of trains. The developer’s project leverages recent advances in geospatial visualization, particularly deck.gl, an open-source library developed by Uber, to create more dynamic and engaging visualizations.
This initiative follows a broader trend of open data projects aimed at increasing transit transparency and user engagement. The use of 3D visualization is still emerging in the transit space, with few comparable tools currently available for London.
It is not yet clear if Transport for London or National Rail have any plans to incorporate similar visualization features into official apps or platforms.
“This visualization aims to make train tracking more intuitive and engaging, with minimal drift in real-time data. It’s a proof of concept that could be expanded for broader use.”

Unconfirmed Adoption and Future Development
It is not yet clear whether transport authorities or app developers will adopt or support this visualization technology officially. The project remains a prototype shared on Show HN, and its scalability, accuracy over time, and integration with existing systems are still being tested.
Additionally, questions remain about data privacy, system robustness, and whether the visualization can handle high traffic volumes or multiple simultaneous users.

Next Steps for the 3D Train Visualization Project
The developer plans to refine the tool, improve data accuracy, and add features such as route planning and alerts. Engagement with transit agencies may determine if the project becomes part of official transit apps or remains a community-driven prototype.
Further testing and user feedback will shape future development, with potential expansion to other cities or transit modes.

Key Questions
How does the visualization track train positions accurately?
The system integrates live data feeds from the TFL API and National Rail, updating train positions in real-time with minimal drift, thanks to the efficient rendering capabilities of deck.gl.
Can this visualization be used on mobile devices?
While designed as a web-based tool, performance on mobile devices may vary depending on browser and device capabilities. Optimization efforts are ongoing.
Is this an official London transit project?
No, this is a community-driven prototype shared on Show HN by an independent developer. There are no current plans for official adoption by transit authorities.
Will this visualization work for other cities?
The underlying technology and approach could be adapted for other urban transit systems, provided similar real-time data feeds are available.
