About Track Design Department:
Main functions of directorate are Research, Design and Development of Rails, Welding Technology, Sleepers, Fastenings, Turnouts, Long Welded Rails, Ultrasonic testing etc. The Track Directorate also provides consultancy to Zonal Railways on the matters pertaining to track, Development and standardization of new innovations reported by the Railways.
The process of development involves framing the specification. In case development is to be followed by field trials, further work involving preparation of detailed trial scheme, collection and analysis of data, change of design, if necessary, and final approval of the item are also undertaken. Multi sourcing and Vendor Development for Specified P. Way Items.
