Data Sources

Level Crossing Data​

Level crossing packages come from 3 different sources.

  • Automated full renewals come from the TRD (Target Renewal Date). This is derived from the commissioning date of the asset, the ERD (Engineers Renweal Date) and SICA assessments.
  • Automated recontrol suggestions are based on interlocking area recontrols (including full resignalling from WT02 , DR20 etc).
  • Manual scheduled work banks which were provided at the start of CP7.

Small Scheme Costs were applied to the following worktypes:

WT02, WT03, WT11, WT12, WT16, WT41, WT65, WT67, WT68 WT90, WT91, WT92, and WT99.
