No doubt its a good train but please tweak its timings...
KR slots are full at this time...
22:05 MAJN SF Ex CST
23:05...
more... Konkan Kanya Ex CST
00:05 Rajya Rani Ex Dadar
Add to it few trains coming in from Gujarat and dep PNVL between 21:30 - 23:00 hrs
At that time... UP route towards CST is given more priority and hence this train might run late....
Try to increase speed and give it a more early departure from Mumbai say 16:55 hrs ex LTT ..
Also Diva halt not required..
