Bro,I think-Why they given more time between SAT & PCOI bcoz PRAYAGRAJ is a terminating station.So 4hr slack is given.PRAYAGRAJ is not terminating,our terminating BSB SO We can give SLACK at BSB & no need at PCOI.
(20903(SF) & 12519(ACEXPRESS) takes only 3.10hr.As our train is DUTONTO is it may go atleast 2.40/45hrs.
BRO the above one is right or wrong?
