1. What is the primary responsibility of a locomotive engineer?
A. Maintain mechanical components of the train
B. Operate the locomotive safely and in compliance with regulations
C. Inspect track conditions daily
D. Oversee ticketing procedures
Rationale: The engineer’s main duty is to safely operate trains in
accordance with FRA rules and carrier policies.
2. When must an engineer perform a brake test?
A. At the start of every shift
B. Before the first trip or whenever consist changes
C. Only when requested by the conductor
D. Every 100 miles
,Rationale: FRA regulations require brake tests before departure and after
any consist modification to verify functionality.
3. What is the maximum authorized speed for a train determined by?
A. Engineer discretion
B. Dispatch approval
C. The track’s class and signal system
D. Weather conditions
Rationale: FRA Part 213 defines maximum speeds based on track
classification and signal protection systems.
4. Which document must always be in the locomotive cab?
A. Employee time slip
B. Yard assignment log
C. Current timetable and special instructions
D. Work order summary
Rationale: The timetable and special instructions contain vital operational
limits and authority rules.
5. If a signal aspect is not clearly visible, the engineer must:
A. Treat it as the most restrictive indication
B. Proceed at authorized speed
,C. Stop and call dispatcher only
D. Wait for a following train
Rationale: Safety rules require assuming the most restrictive indication
when a signal cannot be identified.
6. When approaching a public grade crossing, what must the engineer do?
A. Sound horn continuously
B. Sound horn in prescribed pattern before crossing
C. Dim headlight
D. Reduce speed to 10 mph
Rationale: FRA 49 CFR Part 222 specifies the horn sequence for public
crossings.
7. What color flag indicates a stop signal?
A. Yellow
B. Green
C. Red
D. Blue
Rationale: Red universally indicates stop in railroad signaling.
8. Which of the following requires immediate report to the dispatcher?
A. A headlight failure
, B. Emergency brake application
C. Speedometer error
D. Excessive wheel slip
Rationale: Emergency brake use indicates a potential safety event that
must be reported immediately.
9. What is the function of dynamic braking?
A. Apply friction brakes
B. Use traction motors as generators to slow the train
C. Increase tractive effort
D. Charge the main reservoir
Rationale: Dynamic braking converts kinetic energy to electrical resistance
for controlled deceleration.
10. What must an engineer do before moving a locomotive coupled to cars?
A. Sound the horn twice
B. Ensure air brake continuity test is complete
C. Wait for signal from yardmaster
D. Verify consist weight
Rationale: The continuity test ensures the brake pipe is charged and
operational throughout the train.
