Ok, but what would a weekly rajdhani and bi weekly Duronto get you? Ab samjhiye ki, kyuki ye trains howrah se aati hai, quota pehle se kam milta hai. And these weekly trains were introduced recently, technically aapko kaafi jyada seats mili hai railway ki taraf se compared to what duronto and rajdhani get you. Toh Jo purpose tha in dono ka, woh weekly trains fulfill kar Rahi hai, still keeping it in a route that decreases its speed and increases overall time is not sensible in my opinion.
