I do think that Allahabad can easily fill up Antyodaya to Delhi, but I think it should go to a destination beyond Delhi. Maybe to Ambala/Chandigarh/Ludhiana.
Stoppages of the proposed train MUST be at Fatehpur, Kanpur, Etawah, Firozabad, Tundla, Aligarh and Ghaziabad so that everyone could benefit, instead of skipping which has been the trend in this route nowadays.
