Network Code

The Network Code is a set of contractual rules incorporated into each track access agreement between Network Rail and all train operators.

It covers those areas where all parties are obliged to work together to the same standards and timescales. This includes such areas as:

  • Developing the timetable
  • Making changes to the network or to vehicles
  • Environmental protection
  • Standards of performance monitoring
  • Resolving contractual disputes
  • Managing operational disruption

Any new operators on the network will need to sign up to the Network Code.
