This train should also be speeded up like its RSA train. CST NCJ via CJ least preferred compared to old KR Puram Mumbai NCJ train once upon a time.
But now , CST NCJ. via Kanchi is running with good speed and jam-packed. Both have 1 loco reversal . This should also be speeded up cause it runs 4 days a week and railways should make it arrive at 07:15 AM at NCJ. I think mostly SR would be culprit in these kinda stuff.
