# Railway Engineering Questions and Answers – Need for Construction of a New Railway Line

This set of Railway Engineering Questions and Answers for Freshers focuses on “Need for Construction of a New Railway Line”.

1. What is the most important strategic reason for the construction of a new railway line?
a) To increase tourists
b) To make movement of defence forces easier in case of emergency
c) For creating jobs
d) Because of absence of a railway line

Explanation: In case of natural calamities like flood, earthquake or during threat of war, presence of a railway line is very important. It ensures fast movement of defence forces and relief material to the area.

2. The rate of development of backward areas decrease after the construction of a new railway line.
a) True
b) False

Explanation: The rate of development of an area increases after the construction of a new railway line. A new railway line connects the area to new market places and makes travelling faster. This increases the business and job opportunities.

3. How can we shorten the existing rail link between two points?
a) Construction of new railway line on shorter alignment
b) Increasing the gauge size
c) Increasing the capacity of locomotive
d) It isn’t possible

Explanation: A new alignment, shorter than the one already present can be selected between the two points. This makes construction economical and also reduces the time and fare of travel. This is how the existing rail link can be shortened.

4. What can be done to manage the increase in traffic between two points?
a) Increase the number of sleepers
b) Changing the depth of ballast cushion
c) Converting the single rail lines to double
d) Changing the material of the rails

Explanation: We can deal with the increase in traffic by increasing the number of rail lines from one to two. This will allow multiple trains to travel simultaneously.

5. Which among the following is a step taken by the Indian railways to ensure smooth flow of traffic?
a) Converting all the metre gauge lines to broad gauge lines
b) Converting all the metre gauge lines to narrow gauge lines
c) Increasing the width of sleepers in track
d) Using concrete for construction of sleepers

Explanation: Uniform gauge allows the flow of traffic without any interference. Change of gauge affects the time taken for journey and causes inconvenience to passengers. Thus all the metre gauge lines are being converted to broad gauge lines to ensure smooth flow of traffic.
