Network Code and incorporated documents

The Network Code is a set of rules which is incorporated into, and therefore forms part of, each bilateral access contract between Network Rail and holders of rights of access to the track owned and operated by Network Rail (holders of access rights).

Prior to 1 August 2004, the Network Code was called the Track Access Conditions. Each version of the Network Code (and Track Access Conditions) in effect since 1 January 1996 is provided via this page.

Three further documents associated with the Network Code are also provided. The Delay Attribution Guide (DAG) and the Performance Data Accuracy Code (PDAC) are incorporated into the Network Code itself. The DAG provides guidance on the attribution of delay across the Network and was first published in September 2002. The PDAC relates to the standards of performance data accuracy and was first published in April 1996.

The third document is the Access Dispute Resolution Rules (ADRR). The ADRR form an annex to the Network Code and are used for the resolution of disputes arising usually from access contracts.

The Network Code has recently undergone considerable reform. A number of changes were introduced in October 2007 when the document was re-issued. Discussion on further reform is currently taking place.
