scope:

This SIN applies to those Routes with:

a) Automatic Barrier Level Crossing Locally monitored (ABCL) level crossings;

b) Automatic Open Level Crossing Locally monitored (AOCL) level crossings; or

c) AOCL plus barriers (AOCL + B) level crossings.

Purpose

The purpose of this Special Inspection Notice (SIN) is to:

a) Review the power supply arrangements in place at all types of automatic locally monitored level crossings.

b) Evaluate the practicality of remote condition monitoring of the power supply system, and key sub-systems whose failure can have the same effect as loss of power supply, at all locally monitored level crossings, so that prompt action can be taken to manage the failure.
