The stretch between Dudhnai to Dhupdhara is 29.71 km. Speed trial at 122 km per hour was done by the Commissioner of Railway Safety (CRS)/NF circle, the statement added.
Modern technologies like, robust track structure with the use of all wide base Pre-stressed Concrete (PSC) sleepers and Thick Web Switches which is a new design of sturdier switches on pre-stressed concrete sleepers and can handle higher speeds were used for this double line territory, said NF Railway.
With the laying of a double line, movement of trains can be done in both directions without stop-over crossings at stations which will increase the punctuality of trains. More trains can be run with enhanced speed, it said.
