Now on Monday, 2 JP bound trains will run from SC back to back. But due to LHB rake and HYB connectivity, 19714 passengers may prefer 12720 now.
So, 2 things will happen :
1) Ajmer bound pax will lose a few seats to JP pax, and
2) 19714 will start running empty.
So...
more... in my opinion, NWR should request SCR to change the days of 12720 as it can't change 19713/4 days due to RSA with 12975/6.
In my opinion, 12720 can start departing on Sundays instead of Mondays, to cater weekend rush too.
