Sir, How much trains can run back to back.in konkan? That 19331 slot, this and again at the back nethravathi, Also ur train again overtakes that 19331 slot trains, also by considering crossings enroute only i m saying such a slot is really difficult. Also, ur train reaches PNVL by 14:00 and returning back by 15:00, but see already with similar concept that 12133/34 in MAJN, 12133 most of the days is delayed and 12134 most of the days never leaves MAJN on time and see, delay increases exponentially in konkan and reaches mumbai really late, thats why said to change slots sir..
