The Network Code - modifications

The rail industry can propose changes to the Network Code through Part C. ORR has a role to approve those changes as any modifications to the Code may have a bearing on Track Access contracts.

Part C of the Network Code provides processes by which the Code can be modified.

  • Condition C5, which provides a democratic industry process whereby Network Rail, train operators or ORR can propose changes; and
  • Condition C8, which provides the ORR with a right to make changes.

Recent modifications are listed below.
