Bro, you do have some SERIOUS ISSUES with Allahabad ЁЯЩП.
Please don't target the Trains of Allahabad, they're perfect in their current positions.
I can't speak for Jabalpur but as far as Rewa is concerned, we're fine with existing Anand Vihar Terminal Rewa Express; there's no need for any additional connection especially at the cost of Prayagraj (Allahabad). Rewa is not that big enough to fill a Fully AC 3 Tier Dynamic Fare Train.
Plus...
more... this train is essential to control the summer rush of Prayagraj (Allahabad) Passengers. So ABSOLUTELY NO for Rewa.
As far as Jabalpur is concerned even that place has a strong number of dedicated trains to Delhi and there's no need for any additional train.
