What is the primary function of a fish plate in rail joints?
-
A.
To reduce track curvature
-
B.
To provide better track drainage
-
C.
To join two rails together
-
D.
To hold the sleepers together
Correct Answer:
C. To join two rails together
Explanation:
The correct answer is To join two rails together.
In railway engineering, a fish plate is a metal bar used to connect the ends of two successive rails in a track. Its primary role is to maintain the continuity and alignment of the rail surface while allowing for longitudinal expansion and contraction caused by temperature fluctuations. By securely bolting the rails together through the web, fish plates ensure a stable and smooth transition for train wheels, providing structural integrity and safety to the rail joint. Without these components, the rails could become misaligned, leading to significant track instability.
