Rewa Itwari won't be able to support the number of AC Coaches of Delhi Route from Rewa.
Although I do like the proposal of Bi Weekly Service to Nizamuddin via Saugor would be a blockbuster especially for Satna, Maihar since NR has messed up timings of Mahakoshal Express for these places in order to accommodate Rani Kamlapati Vande Bharat. I'm still not able to see the sense behind changing Mahakoshal Express timings like that, it would mostly end up starting late and would be a disaster during Winters.
