Q&A Instant Download Pdf
1. What is the primary purpose of a track inspector?
A. Repairing locomotives
B. Monitoring train schedules
C. Ensuring the safety and integrity of railroad tracks
D. Operating switches
Rationale: Track inspectors focus on the condition of track components to
prevent accidents and ensure safe rail operations.
2. What is the maximum allowable gauge variation for standard track?
A. 1/4 inch
B. 1/8 inch
C. 1/2 inch
D. 3/16 inch
Rationale: Standard track gauge tolerances are tightly controlled to prevent
derailments; 1/8 inch is the typical maximum variation.
3. Which track defect is characterized by the vertical misalignment of rails?
A. Gauge widening
B. Dip
, C. Squat
D. Rail roll
Rationale: A dip occurs when the track surface sags, creating vertical
misalignment that can affect train stability.
4. What device is used to measure track gauge?
A. Rail lifter
B. Spike puller
C. Track gauge
D. Tamping machine
Rationale: A track gauge is a calibrated tool used to measure the distance
between rails.
5. Which type of rail wear is caused by lateral movement of trains on curves?
A. Vertical wear
B. Flangeway wear
C. Gauge corner wear
D. Head wear
Rationale: Gauge corner wear occurs as the wheel flange slides against the rail
on curves.
6. Which track component helps maintain alignment and distribute load?
A. Spike
B. Fishplate
C. Tie (sleeper)
D. Rail clip
Rationale: Ties stabilize rails, maintain gauge, and help distribute the weight of
trains to the ballast.
7. What is the primary function of ballast?
A. Increase friction for train wheels
B. Support and stabilize track structure
, C. Lubricate rails
D. Prevent vegetation
Rationale: Ballast holds the track in place, provides drainage, and helps
distribute train loads to the subgrade.
8. A “burned rail” is caused primarily by:
A. Excessive rail lubrication
B. Wheel slippage
C. Ballast failure
D. Poor tie condition
Rationale: Burned rails occur when a wheel slips and skids along the rail,
generating intense heat and metal damage.
9. Which inspection method is used to detect internal rail defects?
A. Visual inspection
B. Ultrasonic inspection
C. Track gauge measurement
D. Tie condition survey
Rationale: Ultrasonic inspection can detect cracks and flaws inside the rail that
are not visible externally.
10.Which type of track geometry defect affects the ride quality but not
necessarily safety?
A. Gauge widening
B. Rail break
C. Surface irregularity
D. Split tie
Rationale: Surface irregularities can cause a rough ride but are less likely to
immediately cause derailment.
11.What is the main cause of tie deterioration?
A. Overloading trains
B. Moisture and decay
