Data sources


We have a number of internal data sources that are applied against external feeds to provide train information. These include:

  • Offsetstore
    Used to generate a network wide mathematical model determining the location of trains and their passage through the network. This system also contains our bespoke mapping tables for application against external signalling data feeds.
  • railgeometry
    Our internal system for holding an overall location map of the network to facilitate calculating operational distances and intermediate passing points.

We are working with preserved or community railways to provide realtime information around their services. These trains are tracked using our bespoke Realtime Preserved Trains system and data is presently only available internally.

Network Rail

We make use of the following feeds from Network Rail:

  • TRUST (Train Movements)
    Data with respect to train movements and cancellations across the entire network.
  • TD (Train Describer)
    Providing data with respect to train passage through signalling systems.
  • Schedule
    Providing the base schedule information for day to day running.
  • Very Short Term Plan schedules (VSTP)
    When services are disrupted, the VSTP process allows train operating companies to add and amend schedules.

Data feeds provided by Network Rail contain information owned by Network Rail Infrastructure Limited under this licence.

Transport for London

Transport for London provides a syndicated XML feed from their Trackernet service. Trackernet provides a train departure board feed from the entire London Underground operating area.

Trackernet provides some data for the live departure board functionality at Amersham, Chalfont & Latimer, Chorleywood and Rickmansworth stations. It also provides realtime train movement data between Harrow-on-the-Hill and Amersham for Chiltern Railways services.

The data feeds provided by Transport for London are subject to the Transport Data Service terms & conditions.
