Q

What is the process of approval for use of vehicles in visual track inspection?

1bns

A
  1. TME completes TEF, submit to RAM
  2. Diagrams and work planning systems created explaining inspection method and length
    AND
  3. If vehicle is used in poor lighting, then rquirements of approval for this shall also be met

Q

When will TME’s take a review of use of vehicles?

4

1 bns

A
  1. Adverse no. in intervention limit and immediate action limit faults
  2. Increase in broken/deficient fishplates
  3. Increase in missing/loose fastenings
  4. Increase in faults not picked up by vehicle but by SM
    AND
  5. TME and SM inspections provide validation that vehicle inspection is successful

1bns

A
  1. All S+C is done on foot
  2. 1 in 4 inpections is done on foot
  3. Vehicles are stopped when close inspection is needed
  4. Double track inspection alternates lines between patrols

19
Q

What are 3 things should a inspection diagram include?

A
