Question

Small gaps are left in between between two iron rails in railway track. Why?

• A. For application of track change
• B. To avoid accidents when rails expands
• C. For easy braking of trains
• D. So as to generate noise

Answer 1

The correct option is B To avoid accidents when rails expands

Keeping the gap at the joint of two rail tracks, helps in expansion of the tracks during high temperature. If there is no gap between them, the expansion of the tracks lead to bending of the tracks and in turn can cause accidents.
