The purpose of shock mats and alternate capping layers in railway tracks is to enhance stability, reduce vibrations, reduce pressure and mitigate track degradation. Shock mats, also known as under sleeper pads (USPs), are used to absorb impact forces, reduce strain (reduce pressure) on the ballast layer, and minimize vibrations transmitted to nearby structures.

The correct answer is [D] it can reduce pressure. These strips, known as sleepers or ties, are designed to distribute the weight of the train and reduce pressure impulses, ensuring a smoother ride and reducing the impact on the track and surrounding structures

Shock mats, also known as under sleeper pads (USPs), are used to absorb impact forces, reduce strain (reduce pressure) on the ballast layer, and minimize vibrations transmitted to nearby structures.
Alternate capping layers, like elastometric soft pads, aim to create resilience, distribute impact energy, and decrease ballast degradation and sleeper cracking, ultimately improving track performance and longevity.
