Whatever may be the reason, they are not willing to extend the length of CKP portion, number of GS coach reduced gradually with the increase in number of SL coaches, now it is doing with only one SLR, and the SLR has to be attached and detached always from one end to another, more is the problem when it becomes CKP-TATA Spl. AC Coaches remains locked in Spl. When the CKP-HWH PAss leaves CKP, all General class oad is in the SL Coaches, and almost upto PRR the condition of SL coach is miserable.
