Now this is not a fault of KRCL for this train. I was living in Vasco for 3 whole years and hence know SWR outta there.
1. This Train has a specified slot ex Kalyan 2ith dep at 07:30 hrs. WTT slot sharing with 12519 I guess.
2....
more... SWR is not able to provide a departure slot other than 19:05 from Vasco for it already has filled premium slots after 21:00 hrs viz BOXN freights. So the departure given by SWR is 19:05 hrs.
3. With no other go KRCL is bridging the gap with MAO 20:05 hrs dep and Roha exit at 5 am. So overtake s bound to happen
4. The only option avbl is to either SWR gives a dep slot of say 20:40 hrs from Vasco (Previous dep slot of Vasco YPR)
