It has a TAT of 16 hours at Rewa, a Daytime Intercity between Rewa and Prayagraj (Allahabad) can be started by using its rake. Even if it's given 6 hours of running time (5 hours+ 1 hour of Slack) and 2 hours of TAT at Allahabad Junction, it'd still have 2 hours to cover up any delays incurred in order to leave Rewa on time for Bilaspur.
There's a huge demand for a morning connection to Prayagraj (Allahabad) from Rewa as Afternoon/Evening connection gets covered by Rewa Anand Vihar Terminal Express.
There's immense...
more... pressure on Buses to provide a good morning connection to Prayagraj in the morning, which isn't available as of now.
The RSA would be similar to how SWR uses SR's Kaveri Rake for it's Malgudi Express.
