scope:

This procedure applies to all lines where Network Rail is responsible for maintenance and renewal of the track. It covers annual and short-term planning and applies to Engineering, Maintenance and Information Management. It sets out the process for:

• Identifying and communicating planned traffic flows and their effect on track categories

• Identifying and communicating changes in traffic flows and their effect on track categories.

This specification is supported by a Work Instruction (NR/WI/BUS/02107), which sets out the process to be followed in more detail.

Purpose

To define the process for identifying, evaluating and providing information about track category, planned traffic flows and short-term changes to traffic. This enables informed decisions to be made about asset stewardship, inspection, maintenance and renewal.
