The starting stiffness of a rail pad is designed to not be high so that their relative deformation under the spring clip toe loads is greatly substantial.

Sand Ballast . Sand ballast stands fourth in merits as a ballast material. Coarse sand is better than fine sand. Primarily sand ballast is used for cast iron pot sleepers. It is also used for wooden and steel sleepers where traffic density is very low. Moorum. Moorum is the decomposed laterite rocks. It is found in abundance in many parts of India.The following collection of chapters is based on a revision of the drafts of J.S. Mundrey, Rail Consult India, for the forthcoming 5thEdition of RAILWAY TRACK ENGINEERING. The collection is the result of intensive revision and modification works.

electronics collection 7. xTrack ballast forms the trackbed upon which railroad ties (sleepers) are laid. It is packed between, below, and around the ties. It is used to bear the load from the railroad ties, to facilitate drainage of water, and also to keep down vegetation that might interfere with the track structure. Ballast also holds the track in place as the trains roll over it.

Ballast mats are an efficient countermeasure to reduce vibrations induced in the middle frequency range [3]. In fact, the introduction of the resilient elements beneath the ballast or the sub-ballast, allows achieving a low resonant frequency, i.e., from 20 Hz to 50 Hz, due to the heavier mass above the resilient element.M.
