Then why would anybody prefer Humsafar if it takes more time than other trains. 26 hours me Shipra Kolkata phcha deti h. 29 hours for a train to Kolkata is not preferable. And i am not expecting significant increase in MPS of the CIC route in near future it will take time.
Current situation me this Humsafar is not going to maintain Superfast TT via Singrauli route. Moreover they pay attention to freight more than passenger trains. Traffic uss section me bhi kam nhi h.
