The situation

What has happened

A night possession on the Sunshine to Deer Park up line, work order WO-26-4377, runs from 0:30 am to 4:30 am on Saturday 13 September. The work is fourteen dropper replacements, a registration arm adjustment at structure 1226 and an inspection of the section insulator at structure 1231, in overhead wiring section 34. Traction switching schedule TS-26-0187 is validated and rail traction access RTA-26-0442 is requested. Track protection is provided by the rail operator. Last month a worker climbed a structure before the access was issued, recorded as INC-2026-046, and the Rail Traction Manager wants radio confirmation of the access to every crew member before anyone touches a structure. The down line remains live and trains may run on it.

Your brief. Plan and run the possession: brief the crew with the new access confirmation rule, perform the traction switching to schedule, take the traction access, complete the maintenance and inspection safely with the live down line adjacent, test and verify the work, cancel the access and hand the section back on time with complete records.

What to look for

Evidence guide

Look for the possession, track protection, switching and access steps in the correct order, with the radio confirmation to every crew member recorded before climbing. The live down line must be treated as a controlled hazard. Measurements and the section insulator condition should be recorded, and the hand back should show earths removed, access cancelled and restoration switching complete within the possession window.

The student's evidence summary lists every record they created or changed in the systems named above, their notes and the tasks they ticked. Verify it against the deliverables and your own assessment tool.
