What is Trackser Live?
Trackser Live is a powerful real-time API that transforms raw TfL (Transport for London) data into clean, structured, and accurate train tracking information for the London Underground network.
⚡ Powered by intelligent data processing: We take messy, inconsistent data from TfL's TrackerNet API and apply sophisticated normalization, deduplication, and enhancement techniques to deliver reliable, real-time train positions and movements across the Tube network.
Data Sources
Trackser Live aggregates data from two TfL APIs - TrackerNet (legacy, detailed Underground data) and the Unified API (modern, cross-network coverage). Each source has unique strengths, and we intelligently merge them to provide comprehensive coverage.

What We Do to the Raw TfL Data
The raw TfL TrackerNet API provides basic train data, but it requires significant processing to be truly useful:
- Location Normalization: Standardize station names, track codes, and platform identifiers across inconsistent TfL formatting
- Destination Parsing: Clean and normalize destination information, including handling special cases like depot movements and service patterns
- Track Code Intelligence: Infer accurate location data from track codes when station information is missing or ambiguous
- Stopping Pattern Detection: Identify service patterns, including Chiltern Railways trains and special Metropolitan line routes
- Data Deduplication: Remove duplicate and stale train records with intelligent matching algorithms
- Line-Specific Processing: Apply custom logic for each line's unique characteristics and service patterns
- Vehicle Reformation Tracking: Monitor when train sets are split, joined, or reconfigured during service
- Historical Data Storage: Archive train movements for replay and analysis purposes
What We Produce
Our API delivers clean, structured JSON data that includes:
- Real-time Train Positions: Accurate current locations with normalized station and platform data
- Enhanced Metadata: Train set numbers, vehicle IDs, destinations, directions, and operational status
- Live Statistics: Network-wide metrics including train counts, location distributions, and service coverage
- Historical Replay Data: Access to archived train movements for analysis and debugging
- Map & Line Variants: Different data formats optimized for map visualizations or line-based displays
