Abstract To have the option to foster the western dedicated cargo Corridor (WDFC), India could look for new transportation routes along the corridor to best use its ability and productivity in the transportation of freight. For such a large scale project, modern technologies are used. Dedicated Freight Corridor Corporation of India Ltd. (DFCCIL) was created in 2006 as part of the development of the DFC concept. Indian railroads have been one of the main drivers of the quickly developing Indian economy. The study analyses and interprets such technologies used and their future implications, the challenges that will be faced and conducted to face those challenges. It is to be noted however that the project being an ongoing phenomenon the details in this study are limited to the material available when the study was being conducted. It has been found out that the operations taken by the government are not only influencing the development of freight corridor but there is also focusing on sustainability and environment conservation.
