This set of Railway Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Rail-to-Rail Fastenings”.
1. What is the function of Fish plates in a track?
a) Joining rail to wooden sleepers
b) Joining rail to cast iron sleepers
c) Joining rail to steel trough sleepers
d) Joining rail to rail
View Answer
Explanation: The function of Fish plates is to hold two rails together. It restricts the movement of rails in horizontal and vertical planes. Combination of Fish plates, nuts and bolts are used for this purpose.
2. In the steel used to manufacture fish plates what should be the composition of manganese?
a) Exactly 0.6%
b) Less than 0.8%
c) Not more than 0.6%
d) More than 0.6%
View Answer
Explanation: The steel used to make fish plates are special and should not contain manganese and silicon more than 0.6% and 0.15% respectively. Carbon content should be in the range of 0.3-0.42%.
3. The strength of fish plates are _______ as the rail section.
a) Roughly same
b) Almost double
c) Almost half
d) Roughly half
View Answer
Explanation: The fish plates are so designed that their strength is almost equal to that of the rail section. Also, their sectional area is same as that of the rail section.
4. Why are Combination fish plates used?
a) To connect rails of two different sections
b) To connect two different fastenings
c) To increase load
d) To connect two rails of similar sections
View Answer
Explanation: Combination fish plates are also called Junction fish plates. They are used to connect rails which have two different sections.
5. An expansion gap of 5mm is provided in case of Junction fish plates.
a) True
b) False
View Answer
Explanation: In case of junction sleepers, the expansion gap is eradicated. This is done in order to give more strength to the combination fish plates.
