This set of Railway Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Steel Channel Sleepers”.
1. Why were steel channel sleepers developed?
a) Because of shortage of wooden sleepers
b) They are cheap
c) They are easily manufactured
d) They do not require fastenings
Explanation: Wooden sleepers are obtained from cutting of trees. Shortage of trees led to the development of steel channel sleepers. They are predominantly used on girder bridges.
2. The sleepers made from waste products are called as ________
a) Composite sleepers
b) Durable sleepers
c) Workable sleepers
d) Treated sleepers
Explanation: Composite sleepers developed to replace wooden sleepers were made from waste materials such as used rubber tyres. They have a claimed life span of around 40years.
3. Which type of fittings are used by Composite sleepers?
a) Similar to that of wooden sleepers
b) Twice the strength of wooden sleepers
c) Rubber fastenings
d) They do not require fittings
Explanation: Fastenings are required to hold the rail and the sleeper together. Composite sleepers show similarities with wooden sleepers. Thus they also have similar fittings.
4. Where are composite sleepers developed?
a) In USA
b) In India
c) In Japan
d) In Russia
Explanation: Composite sleepers have been developed indigenously by Indian railways in India. They can be used on tracks if they give appreciable results after testing.
