Description of the network code provisions

The network code sets out the industry procedures governing:

• the way in which service performance is monitored and measured (Part B);
• modifications to the network code (Part C);
• the translation of access rights into the construction of the timetable (Part D);
• environmental protection issues (Part E);
• the contractual arrangements governing changes to the trains used on the network and to the network itself (Parts F and G respectively);
• the Railway Operational Code (Part H);
• changes to access rights (Part J);
• the flow of information between Network Rail and other access parties (Part K);
• the process for establishing performance agreements between Network Rail and train operators (Part L);
• appeals to the Office of Rail Regulation (ORR) (Part M); and
• the Access Dispute Resolution Rules (ADRR), setting out how disputes under access contracts are resolved, are annexed to the network code.

Detailed explanations of each part of the network code can be found in the document itself on Network Rail’s website and in Network code in detail below.

Safety responsibilities, for example through safety certificates and safety authorisations, and Railway Group Standards, take priority over network code obligations.
