The cumulative plastic deformation of rail track subgrade materials under moving wheel loads is a complex problem. The plastic deformation and resilient modulus of subgrade materials subjected to moving wheel loads are a function of Principal Stress Axis Rotation (PSAR).
An electric locomotive is a locomotive powered by electricity from overhead lines, a third rail or onboard energy storage such as a battery or a supercapacitor.
Noise sources associated with the operation of trains include wheel squeal, flanging and idling. Wheel squeal is a highpitched piercing noise that can occur as trains travel on curved sections of track due to the friction between the steel wheel and the top of the steel rail.
The maximum principal stress theory says a part will fail if the total stress developed in it is higher than yield stress of material. The load of train (weight +jerks due to motion) are transferred to rails. The rails resist this load building ...

The Railway Technical Website. A WINDOW ON THE WORLD OF RAILWAY SYSTEMS, TECHNOLOGIES AND OPERATIONS Banner photo: D Gubler ... The wheels slow down and eventually the train stops. The material used for braking is normally in the form of a block or pad. ... The diagram in Figure 1 shows the principal parts of the air brake system.
Abstract — WheelRail systems are intensively subjected to damage caused by rolling contact and slip behaviour between the wheel and the rail. This is caused because of the brake block pushed against the wheel tread to create friction through which energy is dissipated.

In coning of wheel the tread or rim of wheels of railway vehicles is made in the shape of a cone with the slope of about 1 in 20. It maintains vehicle in the central position the track. On straight track, portions of wheels running on track have same diameter. While on curved path, the outer wheel has to cover larger distance than the inner wheel.
principal's message Our School lies in the premises of Rail wheel factory(RWF), Yelahanka, in a sprawling expanse with an imposing building and a vast playground. A .
Wheel Impact Load Detector (WILD) is a Safety System used to identify the defective wheel due to any of the above defects by measuring the dynamic impact on the track at a very early stage and thereby protect the Rail Infrastructure, avoid derailments and catastrophic failures.
