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

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 […]

‘Rescue’ Indian Railway passenger business through statistical indices ‘RSKU’

By on January 17, 2017

Is Indian Railway earning fully towards its non-sub-urban passenger business? There is no published data to corroborate this. Interpreting it by the long waiting list is a wrong assessment. The waiting list continuing in 2016-17 even when there is a drop of 10% passenger as compared to 2012-13 and 10% increase in coach holding. The […]

Has Solar Power taken off  to drive transport sector in future?

Most of the modules for tapping using solar power available in the market have been developed for a wide range of applications in  Industry, residential and office complex. These modules may not immediately suit the Railways need for a few specific applications. It is, therefore, necessary to find the economic usage of the solar energy […]

Selection of Suspension Arrangement of Traction Motors : A Right Approach

Abstract Motor suspension arrangement is of paramount importance for the reliability of traction motors. Another vital input for the selection of traction motor for given motor suspension arrangement is its rotational speed. Non-availability of any complied information on the relationship of rotational speed of traction motors and their mounting arrangement makes the jobs of Rolling […]

Electrical Engineering and Railways

Electrical Engineering is the field of the study of generation, transmission, distribution and use of electrical energy. Electrical Engineering in Railways made its beginning with the responsibility of illumination and ventilation at Railway stations, offices and residential complex and water supply. Thereafter, illumination of passenger carriages with a self generating mechanism added to the responsibility. […]
