1. Which of the following is the primary responsibility of a track
inspector?
A. Operating locomotives
B. Inspecting and maintaining track conditions
C. Scheduling train crews
D. Managing freight logistics
B. Inspecting and maintaining track conditions
Rationale: The main responsibility of a track inspector is to ensure the
track is safe for train operations by inspecting and maintaining track
components.
2. What is the standard gauge for most North American railroads?
A. 4 feet 6 inches
B. 4 feet 8.5 inches
C. 5 feet
D. 3 feet 6 inches
B. 4 feet 8.5 inches
Rationale: The standard gauge for most North American railroads is 4
feet 8.5 inches, which is the distance between the inner faces of the
rails.
, 3. What is the maximum allowable wear on the gauge face of a rail
before it must be replaced?
A. 1/8 inch
B. 3/16 inch
C. 1/4 inch
D. 5/16 inch
C. 1/4 inch
Rationale: Railwear standards specify that the gauge face should not
exceed 1/4 inch of wear to maintain safe wheel-to-rail contact.
4. What type of track defect is described as a separation along the
head or web of the rail?
A. Gauge widening
B. Rail head wear
C. Split rail
D. Rail rollover
C. Split rail
Rationale: A split rail occurs when a rail separates along its head,
web, or foot, creating a potentially dangerous condition.
5. Which tool is commonly used to measure rail alignment and
gauge?
A. Caliper
B. Track gauge
C. Tamping machine
D. Rail saw
B. Track gauge
Rationale: Track gauges are used to check the spacing between rails
(gauge) and proper alignment.
, 6. What is the purpose of ballast under railroad ties?
A. Reduce friction between train wheels and rails
B. Provide electrical insulation
C. Support track and facilitate drainage
D. Prevent vegetation growth
C. Support track and facilitate drainage
Rationale: Ballast supports the ties, maintains track geometry, and
allows water drainage to prevent track instability.
7. What is the term for the vertical misalignment of rails?
A. Gauge widening
B. Rail warp
C. Rail cant
D. Track settlement
D. Track settlement
Rationale: Track settlement refers to vertical misalignment caused by
uneven support or ballast compression.
8. What is the maximum allowable cant deficiency for freight trains?
A. 1 inch
B. 2 inches
C. 3 inches
D. 4 inches
B. 2 inches
Rationale: Cant deficiency is limited to ensure stability at speed;
freight trains typically allow up to 2 inches.
9. Which type of tie is most commonly used in modern railroads?
A. Wooden tie
B. Concrete tie
, C. Steel tie
D. Plastic composite tie
B. Concrete tie
Rationale: Concrete ties are increasingly used for their durability and
stability under heavy loads.
10. A rail surface defect that appears as small pits or cavities
caused by metal fatigue is called:
A. Corrugation
B. Pitting
C. Spalling
D. Shelling
D. Shelling
Rationale: Shelling is caused by metal fatigue and results in small
cavities along the rail surface, which can grow into larger defects.
11. What is the primary purpose of rail lubricators?
A. Reduce rail wear and friction on curves
B. Increase traction on inclines
C. Prevent rail oxidation
D. Clean ballast
A. Reduce rail wear and friction on curves
Rationale: Lubricators minimize friction between rail and wheel
flange, reducing wear on curves.
12. When inspecting track, what is the acceptable gauge range
for standard track?
A. 4' 8" – 4' 9"
B. 4' 8.25" – 4' 8.75"
C. 4' 7.5" – 4' 8.75"
D. 4' 8.5" exactly
