*From Rewa*
While coming from Rewa one could've gotten down at Bhopal Junction to catch Jhelum Express to Pune, Secunderabad Rajdhani, Mumbai CSMT Rajdhani etc. with sufficient gap in case this weekly gets late.
This train gives the option to take Rajdhani from Bhopal as well which won't be possible with Rewanchal Express.
Although I do agree that RKMP has Duronto Trains, but...
more... one simple 2 minute halt would've resolved Rajdhani issue as well. Going back to Bhopal Junction from RKMP becomes risky in case of any delay in this train.
*To Rewa*
For TN, AP and SBC Rajdhani connection it's while going to Rewa from these places. Since it has only 1 hour TAT at RKMP it will more likely get delayed, that would give sufficient time for the above-mentioned trains in case of nominal delay.
While coming from Mysuru to Rewa, have taken Rewanchal Express many times after Bengaluru Rajdhani.
