Now we have 4 different train types running btwn HWH and YPR.. 1 SF exp train, 1 ACSF, 1 Duronto, finally 1 HS... All maintained by SER... DD and Shatabdi are short distance trains otherwise my opinion was to run these two and a Garib rath also so as to have trains of every class between HWH and YPR..
