Tripura had inadequate transport infrastructure in the past, which was an impediment in its development. In order to meet extension requirements of the railway line up to Sabroom, the NFR initiated a project for the stretch length of 112. 00 Km. The alignment of the Railway line passed through more or less flat country and covered two districts namely West Tripura and South Tripura. It passed through towns of Bishalgarh, Udaipur & Belonia in Tripura. Throughout the 112 km section of track length, there was unstable formation in lines causing disturbance to the track parameters. By avoiding the conventional method, NFR was keen to investigate new methods of track bed stabilization, with guidelines from RDSO as a technical advisor & consultant. They were exploring the use of geosynthetic solutions which can increase the effective bearing capacity of an underlying soft subgrade & also prevent intermixing of the soil particles in between blanketing material & subgrade. They also thought about the solution that would offer extension of maintenance cycle- the period between ballast cleaning and replacement operations.
