The project uses data from the Transport for London (TFL) API combined with National Rail information to create a dynamic, interactive 3D visualization of train movements across the London network. Users can select any station platform and see the current position of trains, with minimal drift, along their routes, including connections to major airports like Heathrow and Gatwick.
The visualization is built with deck.gl, a WebGL-powered library that renders complex geospatial data efficiently. The developer, sharing on Show HN, emphasizes that the tool is designed for both transit enthusiasts and the general public, aiming to improve understanding of train flow patterns in London.
It is confirmed that the tool is accessible online and allows users to pick any platform in the network to track associated trains, with real-time updates based on live TFL and National Rail data feeds. The project is still in testing, and the developer has invited feedback for further improvements.
Enhanced Transit Monitoring and Public Engagement
This visualization offers a new way for London commuters, tourists, and transit enthusiasts to understand train movements in real time, potentially reducing travel uncertainty. It could also aid in transit planning, congestion management, and emergency response by providing a spatially accurate, dynamic view of the network. Additionally, the project demonstrates the potential of combining open transit data with advanced visualization tools to improve public information services.

London Transit Data and Visualization Innovations
London’s transit system is one of the busiest in the world, with extensive use of real-time data from TFL and National Rail. Previous efforts have focused on static maps and basic live updates, but this project introduces a 3D, interactive perspective. The use of deck.gl for geospatial visualization has gained popularity in recent years, enabling more immersive data displays. The developer’s approach aligns with broader trends toward open data and innovative transit apps, though this specific 3D visualization is a novel application within the London context.
Similar tools exist for other cities, but few incorporate 3D modeling combined with live train data, making this project a notable development for London’s transit visualization landscape.
“This tool aims to give users a real-time, spatially accurate view of train movements across London, making transit tracking more intuitive and engaging.”

Details About Data Accuracy and Future Features
While the project claims to offer real-time tracking with minimal drift, the exact accuracy level and update frequency are not fully detailed. It is also unclear how the system handles data discrepancies or delays from TFL and National Rail sources. The developer has not yet specified plans for official integration or broader deployment beyond the initial testing phase.
Upcoming Improvements and Broader Access Plans
The developer plans to gather user feedback to refine the visualization, potentially adding features like historical data playback, alerts, and expanded coverage to other transit modes. Future updates may include official support or API access for third-party developers, as well as possible collaboration with transit authorities to improve data reliability and visualization accuracy.
Key Questions
Is this visualization officially endorsed by Transport for London?
No, the project is independently developed and not officially affiliated with TFL. However, it uses publicly available TFL data.
Can I use this tool to plan my journey?
While primarily a visualization, it can help users understand train positions and routes, but it should not replace official journey planning tools.
Is the visualization available on mobile devices?
The current version is optimized for desktop browsers; mobile compatibility is not yet confirmed.
Are there any privacy concerns with this project?
No, as the tool only visualizes publicly available transit data and does not track individual users.
