Track Transition on Bridges or Switch-Over Ramps: Rail Based Urban Transport

With rapid urbanisation, pressures on the urban transport facilities have increased manyfold for reasons of ever increased population and demands for better living. Rail based Mass Rapid Transit Systems (MRTS) be it elevated or underground was the first choice of the Indian Cities, which is changing now with more and more interest coming from 2nd and 3rd Tier Cities, Light Rail Transit System (LRTS) and trolley bus is gaining momentum and this become preferred choice in tier 1 cities as well to provide last mile connectivity, in sync with multi-modal integration to for door-to-door service. In order to control cost, it is now more and more explored to adopt to At Grade Section in such light transit systems. But at junction of such at grade section with Elevated / Underground stretch, it becomes inevitable to provide transition section. This paper aims in elaborating approach to design such transition zone for trackwork.
