Equipment Inspection and Troubleshooting
What this domain tests
Equipment Inspection and Troubleshooting tests pre-trip checks, brake and door tests, safety devices, and the correct response to a fault. The exam favors the safe sequence: recognize, stop or protect, report, then follow the checklist.
Inspection essentials
- Complete a walk-around and cab check: lights, horn, radio, PA, windshield, wipers, fire extinguisher, emergency equipment, and door indicators.
- Perform the required brake test and door test before leaving the yard; confirm that the dead-man or alertness device and emergency brake valve are working.
- Confirm that the train has the required hand brakes, flags, and emergency tools.
- During service, monitor gauges and warning lights; investigate unusual noises, smells, or brake behavior.
Troubleshooting sequence
- If a fault affects safe movement, stop the train and secure it.
- Protect the train and notify the rail control center with train number, location, and symptom.
- Follow the approved checklist; do not bypass a safety device or repeatedly reset a breaker without authority.
- If the fault cannot be corrected safely, request instructions and take the train out of service.
Worked example
A door indicator will not show closed after you cycle the doors. Do not take power. Reopen and inspect the door for an obstruction, check the door panel for a fault indication, and cycle once per procedure. If the indicator still fails, keep the train stopped, notify control, and follow the instruction for a defective door; moving with an unconfirmed door interlock is unsafe.
Traps
Assuming a warning light is a false alarm; resetting breakers endlessly; leaving the cab to inspect a fault without securing the train; and working around a failed safety device.
