NR NR/L3/OPS/021/08 ISSUE 2 PDF

This module describes the business process to manage the threat of Adverse and Extreme Weather (A/EW) and the risk posed to earthwork assets. 

The business process is the operational counterpart to NR/L2/CIV/086/Mod09 and provides linkage between the Earthworks A/EW Plan and the Integrated Weather Management Plan (IWMP) for operational response. 

This module applies to all earthworks within the Network Rail boundary, and slopes outside the boundary which may affect Network Rail infrastructure.

Purpose 

This module describes the operational requirements for the management of earthworks during Adverse / Extreme Weather (A/EW). 

This procedure manages the control in NR/L2/OPS/021, mitigating the following risks: 

a) loss of track support and / or geometry; 

b) slope failure leading to loss of kinematic envelope and / or track geometry.
