Correct Answer - Option 3 : Water logging of rails

Concept:

A rail track is liable to get distorted or buckled, particularly in hot weather when the compressive forces in the track exceed the lateral or longitudinal resistance of the track.

A track can buckle due to the following reasons:

(a)  Inadequate resistance to track due to deficiencies in the ballast.

(b) Ineffective or missing fastenings.

(c)  Laying, distressing, maintaining, or raising the track outside the specified rail temperature range, especially is hot weather.

(d) Failure to lubricate the SEJs in time.

(e)  Excessive creep, jammed joints, sunken portions in a welded track.

Therefore, Water logging does not causes buckling of track rather it causes track circuit failure.
