'Ballast is a prime component of the track that acts as a vibrant medium to transmit from the rail surface the weight of the train down to the formation, the wells set on prepared terrain. It ensures a cushioned and smooth run for the train and precludes the longitudinal displacement of the rail called creep. In ballast-less track, as the name suggests the ballast is replaced by a bed of concrete. The rails rest on rubber pads placed over concrete sleepers, which are fixed on the concrete bed.

The ballast-less track helps to eliminate the evils of dust and noise pollution and proves suitable for underground railway also. So it is also safe for travel.

The MRTS in Chennai is equipped with a ballast-less track. The rubber pads on which the rails rest help to absorb the vibration caused due to the movement of the train. The cost involved in laying a ballast-less track is more initially but it requires less recurring maintenance cost.

Tracks laid on concrete beds

Reduced wear and tear, easy maintainability

Can prevent derailments

10 times more expensive than normal track

Passengers will feel less vibrations while travelling
