This set of Railway Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Rail Joint Types”.
1. Which of the following joint is not classified according to position of sleepers?
a) Supported joint
b) Suspended joint
c) Bridge joint
d) Square joint
View Answer
Explanation: Rail joints can be classified based on position of sleepers or position of joints. According to position of sleepers, the joints are Supported joints, Suspended joints and Bridge joints. Square joint is joint classified based on position of joints.
2. Which of the following statements regarding supported joints is incorrect?
a) Rails are supported on sleepers
b) No wear and tear
c) No cantilever action
d) Duplex sleeper is a type of supported joint
View Answer
Explanation: Supported joints have no cantilever action, but it does not reduce the wear and tear of the rails. Wear and tear of rails as well as sleepers occur and poses a problem for their maintenance.
3. Which of the following can be used in case of Bridge joints?
a) Metal flat
b) Bridge plate
c) Metal flat or Bridge plate
d) Extra sleepers
View Answer
Explanation: The sleepers on either side of a bridge joint are connected. For this purpose a metal flat or a corrugated plate also known as a Bridge plate is used. These joints are generally not used on Indian Railways.
4. How are the joints in rails located in Square joints?
a) Exactly opposite to each other
b) ln a staggered manner
c) Distance of 10m on one rail and 7m at other
d) Can be arranged according requirement
View Answer
Explanation: Joints can be classified as Square and Staggered joints based on their position. In square joints their location is exactly opposite on each rail. Square joints are most commonly used on Indian Railways.
5. Staggered joints are preferred on curved tracks.
a) True
b) False
View Answer
Explanation: Joints in one rail are staggered to the joints in other rail. They hinder the centrifugal force which pushes the track outwards on joints and thus is used on curves.
