This set of Railway Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Advantage & Essentials of Track Maintenance”.
1. What should be done to improve the loose sleepers and the disturbed track geometry?
a) Replace it with new ones
b) Proper Maintenance
c) Additional parts should be added
d) Travel should not be permitted
Explanation: Moving rails cause disturbance in the track geometry, effects alignment, gauge and other track components. Thus the track needs to be maintained which offers safe and comfortable journey.
2. Which of the following statements is false?
a) Life of track is independent of track maintenance
b) Tightening a bolt or Hammering dog spikes is a part of track maintenance
c) Maintenance saves money
d) Neglecting track maintenance may render it unrepairable
Explanation: Regular track maintenance helps in reducing operation costs and fuel consumption. Proper maintenance of track ensures lesser wear and tear of components and thus increases the life of track.
3. What purpose does a Jim Crow serves in track maintenance?
a) Removes kinks
b) Removes rails
c) For digging out ballast
d) Squaring of sleepers
Explanation: For Through packing examination of rails, sleepers and fastenings is done. The defective sleepers are removed and loose fastenings are tightened. A Jim Crow is used to remove any kinks if present in the rail.
4. How is gauge adjustment done in case of wooden sleepers?
a) With keys
b) Replacing the gauge components
d) Refitting the dog spikes at a new location
Explanation: In Wooden sleepers gauge adjustments should be avoided. This is because it can be done only by removing the dog spikes and refitting them at some other location. New holes are bored and spikes are re-driven.
5. Cotters are used for the gauge adjustment of which of the following types of sleeper?
a) CST-9 sleepers
b) Wooden sleepers
c) Steel trough sleepers
d) Concrete sleepers
Explanation: Gauge adjustment is case of CST-9 sleepers is done with the help of cotters. Gauge can be adjusted to a maximum extent of -3mm to +10mm. Keys are used in case of steel trough sleepers.
6. Packing of sleepers is done by applying the scissor packing method.
Explanation: Packing of sleepers is done by scissor packing method. While the packing is carried out the second rail is brought to correct cross levels to ensure proper surfacing of the track. The top and alignment should be checked carefully after packing.
