KHH is much more bigger and important station than PBW. and hence halting at PBW and skipping KHH is impossible just do the reverse. Skip PBW and halt at KHH. also KGM does not have pf that can accommodate rake of more than 18 coaches and 17 in case of LHB.So join/disjoin extra coaches at either LKU or BE or shorten the rake length.
