Requirements of an ideal Sleeper Following are the requirements of an ideal sleeper: 1. The initial, as well as maintenance cost, should be minimum. 2. The weight of the sleepers should be moderate so that it can be handled easily. 3. It should be easy to handle so that gauge may be adjusted easily and …
Functions of Sleepers Sleepers – Sleepers are transverse support for a railway track to give stiffness to it. Transverse sleepers were introduced on the railway track for the first time in 1835 and now they have been accepted universally. Functions of sleepers are as follows: 1. To hold the rails to correct gauge and alignment. 2. …
Buckling of Rails The displacement of the track from its original position is known as buckling of the rail. Buckling takes place due to the development of excessive compressive forces in the track due to insufficient expansion gaps in the track. Causes of Buckling Buckling of rails takes place due to the following causes: Due …
Requirements of an Ideal Rail Section Following should be the characteristics of an ideal rail section: The rail should have adequate lateral and vertical stiffness. The shape of the bottom of the head and top of the foot should be such that the fish plate could be fixed easily. The centre of gravity of the …
What is Creep of Rail? Creep is defined as the longitudinal movement of the rails in a track in the direction of motion of the locomotive. It is common to all railway tracks but varies considerably in magnitude. In some places, its value is negligible but at some places, its value may be as high …

What is Rails? Rails are steel girders placed an end to end to provide a level and continuous surface for the movement of trains. Functions of Rails The rails provide the level and continuous surface for the movement of trains. The rails provide a smooth pathway to trains. The pathway has very low friction. The friction between the wheels …
What is Ballast? Ballast may be defined as a layer of broken stone, gravel, moorum or any other material placed under and around the sleepers to distribute the load from the sleepers to the formation and for providing drainage as well as providing lateral and longitudinal stability to the track. Function of Ballast In Railway Track It …
