Bro ,I think Railway have taken policy decision to do away with slip coaches .Used to travel in 14041/42,it used to have detachment attachment ar 2 location in 334 km route with 2 LR .{HW and najibabad jn}
One such train which had good patronage was 12687/88 but here Railways went in Reverse way retained slip train. Of CDg as full train and discontinued DDN portion..It was very convenient for old people going to haridwar , rishikesh and Chardham tour
