Prayagraj is a legend. To even create its duplicate/clone would be difficult before EDFC is ready in the section and is not really needed. For Prayagraj, its mostly E-to-E pax and is always filled to limit or more. Make 12275 into a SF Passenger like Vrindavan and have many more halts. Let pax waiting at smaller stations in the dead of night have an opportunity to travel in one more train. Simply forget 1A/2A as its pax would get irked by so many halts. They have original Prayagraj.
