Failure of Stainless Steel Wire Ropes in in Automatic Tension Device

By on April 18, 2021

Introduction On first hearing about this failure, my reaction was that of disbelief. How can a wire rope made of such strong material fail? Break? Particularly when the load supported did not appear to be heavy! Hence disbelief. I had never worked in the Traction distribution where such a device is used. Having analysed the […]

Role of Adhesion in Rail Traction

Synopsis: Adhesion is central to any discussion on traction- electric or otherwise. Therefore, it has remained a key issue in the development of railways.  In the context of high tractive-effort and power requirements from locomotives and limitation on axle loads in IR, need for achieving high adhesion has been underlined. The article surveys important developments […]

Weight Transfer Compensation in Locomotives

By on April 13, 2021
Weight Transfer Compensation in Locomotives

The development of tractive effort by locomotive causes off-loading of some axles and over-loading of others-a phenomenon commonly known as weight transfer. Electric locomotives WCG-2, WAM-4, WAG-5, WAG-7& WCAM-3 have a provision for compensation of weight transfer by selective shunting of fields of traction motors. This paper reviews circuits of these locomotives to examine the […]

How Resistance is important in understanding Electricity?

Resistance is the hindrance in the flow of electron and is similar to friction in mechanical movements. It is the property of a substance due to which it opposes (or restricts) the flow of charge or electrons through it. In metals, there is a significant presence of free or loosely-attached electrons in their atoms which […]

Indian Railway Context – Sanding to improve adhesion

In Indian Railway context, sanding is one of the important design and functional requirement to improve adhesion between rail and wheel during traction. The requirement has gone so deep in the background of policy makers that it is difficult to believe a traction equipment without sanding gear. Any case of an investigation into wheel slipping/stalling  […]

Mechanized measurement and inspection – a help to cut down maintenance cost

Mechanized measurement and inspection – a help to cut down maintenance cost

Failure of integration of new technologies with the traditional system of working is the main reason for Indian Railways failure to cut down cost. Introduction of new technologies in any system cannot be done overnight and is always a well-planned engineering process. If not, both system runs parallel and not deriving any benefit to the […]
