Knowledgebase (KB)

About Knowledgebase

Knowledgebase (KB) is the name given to the backend engine that contains all the textual content provided on the National Rail (NR) website. It holds a range of rich supplementary information, both static and real-time, about travelling by train on the GB rail network.

KB contains a database of static information about the facilities at each of the 2500+ stations on the network, including specific information about available facilities for those with accessibility needs. Whilst this data is held centrally in the NR Knowledgebase, it is kept up-to-date by each of the TOCs responsible for operating and maintaining the stations. 

Another primary content base held in KB is contextual information about real-time disruption to train services, along with detail about planned changes to services due to engineering work. Other content includes information about the train operating companies, ticket types, promotions, fares and restrictions.
