There is nothing like that on Indian Railways. Quite honestly the train stations require just as much, if not more, fighting than the airports and reward you with a 16 hour or longer journey on most of the legs you are looking, food cabin and "amenities" of a most uncertain quality.
On the plus side the train is cheaper, but not terribly so in AC1. Fly.
