Abstract

Abstract: This work aims at value addition to the response in times of train derailments and accessibility to those areas which are inaccessible via rail during emergency situations, by combining the technological up-gradation and reduction in consumption of overhead time with the general principles of hydraulics; thus, contributing to the larger social cause of faster rescue and minimum train rescheduling in times of derailment in the Indian Railways. A rail-road vehicle is a vehicle which can operate both on rail tracks and a conventional road. Conventionally propulsion is through the tires, the rail wheels being free-rolling; the rail wheels are raised and lowered as needed but the authors' design provides drive to the rail wheels for propulsion. The heavy load breakdown crane of the Indian Railways is its most important asset in Accident Response. But, the use of the existing breakdown cranes is limited only to tracks. Thus, bringing the crane to the site of the accident means travelling it over kilometres of railway lines which, in turn, means loss of response time. The design made by the authors includes the use of a hydraulic circuit for the lowering and lifting of rail and road wheels; the complete hydraulic system installed onto a convertible rail road truck provided with a breakdown crane that enables it to be operated either on road or on railway tracks, and to carry loaded or unloaded railway cars when on rail.
