Creep of Rails

Creep of Rails It is a horizontal movement of rails in a track. It can be minimized but cannot be stopped. Causes Of Creep| There are three main causes of Creep Wave motion of trains. Expansion and contraction of rails due to variation in temperature. Due to starting, accelerating, slowing down (decelerating) and stopping of trains. Wave Motion When train ... Read More »

Types Of Crossing Square Crossing Diamond Crossing Cross Over Scissor Crossing Symmetrical Split SQUARE CROSSING When to railway lines cross each other at 90o it is called Square Crossing. DIAMOND CROSSING Angle of intersection (Crossing angle) of two tracks is when not 900 , then it is called diamond crossing, CROSS OVER A cross over is introduced to transfer a ... Read More »


Wear at Curves

WEAR OF RAILS TYPES Wear on Head of Rail Wear on Ends of Rail Wear of Rail on Curve WEAR ON HEAD OF RAIL Wear on head of rail is due to abrasion on moving rails. Due to grinding action of sand or dust between the rails and wheels of the train. When train starts or applies brakes, the wheel ... Read More »


Double Headed Rail

RAILS Rail is an iron beam. Its main function is to provide a most economical, smooth and level surface for the smooth passage of heavily loaded vehicles at great speed. The two RAILS of the track also serve as a lateral guide for the running of the wheels. Types of Rails Rails can be classified into the following categories: Double ... Read More »

Permeability Permeability is defined as the property of a porous material which permits the passage or seepage of water (or other fluids) through its interconnecting voids. A material having continuous voids is called permeable. Gravels are high permeability while stiff clay is the least permeable, and hence such a clay may be termed impermeable for all practical purposes. The flow of ... Read More »
