Instead of starting new trains, the new mantra should be coach argumentation. This is a seven coach train, These coaches can be easily attached on DDR janshatabadi on a trial basis. If this works out, the railway network would be free of one extra burden.
I m strictly against LHB running with 15 or seventeen coaches. Look at BCT duronto, runs with 17 coaches . BCT Rajdhani, AK Rajdhani, BCT Duronto can be made 22 coaches train before introducing any new train.
