TL;DR
A developer has created a 3D visualizer for London trains using deck.gl, combining Transport for London and National Rail data. It allows users to track trains with minimal drift and see connections to airports. The project is currently in a demo stage and aims to enhance transit awareness.
A developer has introduced a visualizer that tracks London trains in 3D using deck.gl, providing real-time updates from TFL and National Rail APIs. The project aims to give users a detailed, spatial understanding of train movements across the city and to airports, enhancing transit tracking tools.
The visualizer, accessible via a web interface, allows users to select any station platform in London and follow the train’s route with minimal drift, thanks to the integration of live data feeds from Transport for London (TFL) and National Rail. The developer, sharing on Show HN, emphasizes that the tool offers a dynamic, 3D perspective on train locations, which is a significant upgrade over traditional 2D maps.
The project leverages deck.gl, a WebGL-powered visualization library, to render detailed 3D models of trains and tracks, providing a more immersive experience. The data updates in near real-time, allowing users to see train movements as they happen, including connections to major airports like Heathrow and Gatwick.
While the tool is currently in a demo phase, the developer has indicated plans to improve accuracy and add features such as route predictions and alerts. The visualizer is accessible online, with instructions on how to select specific trains and routes for tracking.
Implications of 3D Transit Visualization for London Commuters
This project introduces a new way for London commuters and transit enthusiasts to visualize train movements in a more detailed and spatially accurate manner. By integrating live data into a 3D environment, it could enhance user understanding of train schedules, delays, and connections, especially for airport travelers.
Moreover, the visualization could serve as a prototype for future transit apps, offering more engaging, informative, and real-time tracking options. It also demonstrates the potential for open-source tools to augment existing transportation infrastructure and data transparency.

Background on London Transit Data and Visualization Tools
London’s transit system is extensively covered by TFL and National Rail APIs, which provide real-time data on train locations, schedules, and delays. Existing apps and websites mainly offer 2D maps or static schedules.
Recent years have seen increased interest in open-source transit visualizations, but few have integrated 3D modeling with live data, especially for a city as complex as London. The developer’s project builds on these trends by combining modern web graphics with transit data.
This effort aligns with broader movements toward more immersive, data-driven transit tools, which aim to improve commuter experience and transit system transparency.
“This visualizer offers a new perspective on London’s train network, making it easier to understand routes and connections in a spatial context.”

Key Questions
How does the visualizer track trains in real-time?
The tool uses live data feeds from TFL and National Rail APIs, processed through deck.gl to render train positions in 3D. However, the accuracy depends on data update frequency and API reliability.
Can I see trains heading to specific airports?
Yes, the visualizer includes options to track trains heading towards Heathrow, Gatwick, and other major airports, providing real-time spatial context for travelers.
Is this available for public use now?
The project is currently in a demo phase accessible online. Developers plan to improve features and accuracy before wider deployment.
Will this replace existing transit apps?
It is unlikely to replace official apps but could serve as a supplementary tool offering a more immersive visualization experience.
