Knowledgebase is RDG’s Content Management System providing customer friendly information on the railways and associated products. It contains a wealth of static and real-time information about traveling by train on the GB rail network, such as information about station facilities, service disruption, and engineering work.

Data is available on the National Rail Data Portal through two subscription types:

  • Real Time incidents - for new, modified and deleted Incidents
  • Knowledgebase API - for requesting the latest information on the following static data
    • Companies (TOCs)
    • Incidents (Service Disruptions and Engineering Works)
    • National Service Indicator (NSI)
    • Promotions (Public)
    • Stations
    • Ticket Restrictions
    • Ticket Types

Accessing the Knowledgebase Feeds

To access the RDG Knowledgebase feeds, you must have an account on the National Rail Data Portal (NRDP) at By creating an account, you can register for a subscription to the Knowledgebase API and the Knowledgebase Real Time Feeds.

To receive Knowledgebase Real Time Incidents, select Knowledgebase (KB) Real Time Incidents under the Knowlegebase (KB) subscriptions. The connection information required to start receiving Real Time Incidents is located on the My Feeds page.

To receive Knowldegebase static data, select Knowledgebase (KB) API under the Knowledgebase (KB) subscriptions. The My Feeds page will then display details about accessing the latest versions of Ticket Restrictions, Companies, Incidents, National Service Indicator, Promotions (Public), Stations and Ticket Types files from Knowledgebase.

Important - Please note NRDP accounts expire after an extended period of inactivity. The unused account expiry period is currently set to 30 days. If you create an account and do not consume any of the feeds during this time your account will be deleted. If your account has been deleted, you will receive a notification email, and you will be able to re-register for a new account.

Internal KB URLs

Some endpoints are currently accessible without authentication on subdomains reserved for internal use only. Internal KB was originally firewalled, this was removed in March of 2020, but it may return to being firewalled without warning. If a URL you're using starts with anything other than, you're probably in the wrong place!

RDG Knowledgebase APIs

Knowledgebase API

After selecting the Knowledgebase (KB) API checkbox subscription type on NRDP, you can receive the Knowledgebase xml files in two steps via a REST client.

Generate Authentication Token

See the Authentication section on the National Rail Data Portal article

Make a call for each file

Once you have a valid authentication token, you can make an HTTP GET request. Supply the authentication token in a header named `X-Auth-Token`:


A successful response will result in the requested file:

   <?xml version="1.0" encoding="utf-8"?>

If authorization failed, the response will be an HTTP 401 Unauthorized:

       "timestamp": "2019-02-13T11:50:16.048+0000",
       "status": 401,
       "error": "Unauthorized",
       "message": "Unauthorized",
       "path": "/api/staticfeeds/4.0/ticket-restrictions"

If you are not subscribed to the Knowledgebase API, the response will be an HTTP 403 Forbidden:

       "timestamp": "2019-02-13T11:51:29.992+0000",
       "status": 403,
       "error": "Forbidden",
       "message": "Forbidden",
       "path": "/api/staticfeeds/4.0/ticket-restrictions"


In the stations data, London St Pancras and Ashford International both have have two entries each, intended to correspond to domestic services and facilities (STP and AFK), and those dedicated to international facilities (SPX and ASI). These second entries are not maintained, and these CRS codes, derived from underlying Network Rail data, are not recognised by LDB, or in the Darwin push port reference data, which mantains the National Rail convention of one CRS code per station (here STP and AFK). These entries bear confusingly similar names to the more canonical ones, and may be sorted before them, something to consider if you're allowing a user to search stations.

Real Time Incident Feed

The real-time incidents feed details the creation, modification, and deletion of Knowledgebase incidents in real-time. The underlying information is the same as is available through the HTTP API (which can be used as a snapshot, if necessary), but its real-time nature is useful for tracking state changes more reliably, efficiently, and quickly. Messages from the real-time incidents feed can be received using either STOMP or Openwire. After selecting the Knowledgebase real-time incidents checkbox on the edit account page, connection information (host, credentials, and topic name) will now be shown in the relevant section on your My Feeds page.

Please note:

  • If using STOMP, your client must support STOMP v1.2.
  • Knowledgebase message bodies are not compressed, unlike the Darwin push port.
  • The opening XML tag is malformed, and should be PtIncident instead of Simple string substitution can resolve this if it presents a problem using the schema. This issue does not affect the incidents file retrievable over HTTP.
  • Topic advisory messages are disabled on the KB Real Time Incidents messaging host, so you must also connect with this facility disabled if using Openwire (e.g. by setting watchTopicAdvisories=false if using NMS)
  • The feed is relatively low volume with typically only a few messages per hour and often gaps of several hours overnight; if monitoring message volumes, or testing, you should take this into account.


Each frame from the real-time incidents feed contains the following headers:

  • INCIDENT_MESSAGE_STATUS: either NEW (a new incident message), MODIFIED (a change to existing incident information), or REMOVED (incident deletion)
  • INCIDENT_ID: the ID of the KB incident

Example Real Time Incidents Bodies

The following are examples of real-time incidents messages which include new, modified and deleted incidents.
