The existing slip service is being run by SER and is already running daily.......i dont think starting a new train which is bi-weekly will be a favourable option.
Even ECR which managers DHN-Allp [13351/13352] is also raising the same demand. Quiet surprised that the collective demand is a,so not resulting in a favourable response. I think 2 issues could be [1] getting a best time slot [2] availability of rakes. A full fledged train will at least require 15 coaches and these trains run now with 6 rakes !!!
