This assessment is based on the analysis, simulation and testing conducted by Transportation Technology Center, Inc. (TTCI) Worn Wheel Profile 80 % of the track in Indian Railways is having rails which are already worn in service. Standard wheel profile running on these tracks tend to wear to a specific profile within short time itself, and further wear from this profile is very slow. Hence if the wheels are turned initially to this worn wheel

  1. The rail profile is the cross sectional shape of a railway rail, perpendicular to its length.. Early rails were made of wood, cast iron or wrought iron. All modern rails are hot rolled steel with a cross section approximate to an I-beam, but asymmetric about a horizontal axis (however see grooved rail below).The head is profiled to resist wear and to give a good ride, and the foot profiled to.

  3. Wheel Parameters Wheels are constantly exposed to high mechanical stress and have a decisive influence on the running behavior and general driving comfort. That is why a regular inspection is needed to ensure operational reliability. As for the rail track, wheel inspection and measurement must include surface and internal flaws detection
  4. Out-of-round wheels generate impact forces at the wheel-rail interface, which are transferred to train and to track components including rail and both bolted and welded rail joints, prestressed.

2) Due to the inherent nature of large scale trains, the wheel and track standards for Standard (Sx.2) and Deep Flange (Sx.3) are identical except in terms of flange width and depth. 3) Developing a single wheel profile for all of large scale is not recommended nor needed due to the fact that there ar wheel and/or rail profile can greatly affect the wheel/rail interface contact angle. Managing the contact angle as outlined in this standard is an integral part of any wheel/rail interface management strategy. The flange angle is used as an approximation of the maximum contact angle.

A standard-gauge railway is a railway with a track gauge of 1,435 mm (4 ft 8 1 ⁄ 2 in).The standard gauge is also called Stephenson gauge (after George Stephenson), International gauge, UIC gauge, uniform gauge, normal gauge and European gauge in Europe. It is the most widely used railway track gauge across the world, with approximately 55% of the lines in the world using it

As a consequence of this complex wheel-rail contact condition, two distinct wear regions appear on the wheel profile: one on the flange and the other the thread, see Fig. 6.1.Wear rates in these two regions depend on a variety of factors, such as the vehicle design, the service profile (e.g. track curvature, cant deficiency, etc.), the status of the contacting surfaces (including the.
