Railway Engineering Questions and Answers Part-12

1. Why is the section where earthwork is to be donedivided into different zones?
a) Earthwork required is less
b) For early execution of earthwork
c) To provide different facilities to sections
d) To increase traffic flow

Answer: b
Explanation: Dividing earthwork into different zones makes the work very convenient. Each zone has a different Tender allotted which enables simultaneous progress of work in zones. Thus division of section in zones allows timely execution of earthwork.

2. What are the factors on which the design of Bridges of railway are dependent?
a) Topography of the country
b) Type of stream to be covered
c) Topography and Type of stream
d) Topography, type of stream and Local bodies of the area

Answer: c
Explanation: The Bridge should be so designed that it should easily carry the load of the heaviest vehicle locomotive that will pass over it. The design of bridges like RCC, Steel, and PRC depend upon the topography of the area and the stream which lies in its path.

3. Which of the following is not a part of Plate laying or Track linking?
a) Laying sleepers
b) Formation of embankment or cutting
c) Laying rails
d) Laying fastenings

Answer: b
Explanation: The laying of rails, sleepers and fastenings is done after the construction of Formation. But construction of formation is not a part of Plate laying or Track linking.

4. In which method of Plate laying a temporary line is laid by side the of the proposed railway track?
a) Tram line method
b) American method
c) Telescopic method
d) British method

Answer: a
Explanation: In Tram line method a temporary line is laid adjacent to the proposed track. This track is helpful for carrying track materials to the work site.

5. On what type of Terrain is the Tram line method most useful?
a) Hilly terrain
b) Rolling terrain
c) Flat terrain
d) Its suitable for all terrains

Answer: c
Explanation: Tram line method is useful in case of a Flat terrain. This is because laying of tram line on flat ground is convenient, cheaper and faster as compared to other terrains.

6. In Side method what is used for carrying track material on site?
a) Trucks travelling on a service road
b) Trains just like in Tram line method
c) With the help of cranes
d) Humans carry the material

Answer: a
Explanation: Side line method is slightly different than Tram line method. This is because it uses Trucks which travel on a service road parallel to the track for carrying track materials to the work site.

7. For what type of banks, Borrow pits are provided only on one side of the track?
a) High banks
b) Low banks
c) High and Medium banks
d) Does not depend on type of banks

Answer: b
Explanation: If land available is cheap, separate land should also be made available for Borrow pits. Borrow pits may be on one or both sides of the track for low banks and high or medium banks respectively. In case of costly land area, no Borrow pits are provided and earth is taken from neighbouring areas.

8. Why are Service buildings required?
a) For providing services for running the trains
b) To maintain the tracks
c) For residential purpose
d) For residential purpose

Answer: a
Explanation: Service buildings are required so that the staff can work there for smooth functioning of station and running of trains. These service buildings include Station master’s administrative centre, Telegraph office, etc.

9. Which is the most widely used method for Track linking and Plate laying?
a) Tram line method
b) American method
c) Telescopic method
d) Side method

Answer: c
Explanation: Telescopic method is extensively used in Indian Railways. In this method, material is unloaded after taking it to the base depot. The track is then laid and packed.

10. In telescopic method, the track material is carried to the site through the same track which is to be laid further.
a) true
b) false

Answer: a
Explanation: In telescopic method, for further laying of the track, material is carried up to the advanced rail head with the help of a Dip lorry. The track is then linked and packed.
