….let's share our railways knowledge

Mahesh Chandra

His professional career spanning over 37 years has been primarily focused on rolling stock for railways and metros railways. He has dealt with all aspects of rolling stock -design, manufacturing, operation and maintenance. In the recent years, he has been involved in metro railway projects as a rolling stock expert as well as on management of Consultancy services. Indeed, He also led the Indian Railway’s initiative to start rebuilding of electric locomotives at mid-life. He was associated with Transfer of Technology at several stages in his career. He had a stint as a Professor of locomotives and rolling stock. He has published a large number of papers in international and national journals e.g. International Journal of Quality and reliability (Emerald), Indian Railway Technical Bulletin (RDSO) and IRIEEN, Nasik journal on issues related to rolling stock and OHE. He worked for NTPC in the beginning of his career.

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

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 […]

CONTAINER TRAIN – NEED FOR A NEW LOCOMOTIVE

Synopsis: The paper examines the dynamics of the CONRAJ train running on the Western Railway. Based on analysis of data obtained by foot plating, a train resistance curve for the CONRAJ train is constructed. The authors conclude that there is a considerable mismatch between the characteristics of the train and that of the locomotive used […]
