Discussion Forum : Railways - Section 3 (Q.No. 32)
32.
Pick up the incorrect statement from the following:
Answer: Option
Explanation:
- Ends of adjoining rails should be in true alignment: This is correct. Proper alignment ensures smooth passage of trains and prevents excessive wear and tear.
- Rail joints should be as strong as the rail section itself: Ideally, this is the goal. However, in reality, joints are often the weakest points in a rail track. Modern welding techniques are improving joint strength.
- Rail joints should be elastic laterally as well as vertically: This is correct. Elasticity allows the track to absorb vibrations and impacts from moving trains, reducing stress on the rails and supporting structure.
- Ends of adjoining rails butt against to give a continuity: This is incorrect. Rails are not simply butted together. A small gap is left between the rail ends to allow for thermal expansion. If they were butted directly, the rails would buckle in hot weather. Joints are designed to bridge this gap while maintaining alignment and load transfer.

The incorrect statement is option D.
**"Ends of adjoining rails butt against to give a continuity."**
This statement is incorrect because, in railways, the ends of adjoining rails are typically joined by rail joints or fishplates, which allow for some movement and accommodate thermal expansion and contraction. Simply butting the ends of the rails against each other would not provide the necessary continuity or accommodate these changes in length. Proper rail joints or welded connections are required to ensure continuity and safety.

My dear senior, you are correct
