Earning of 12952 NDLS-BCT Rajdhani Express is around 26lakh/ trip. (Its peak earning, because on 3rd January 2018 hole train was fully packed with dynamic fare)
Yesterday I calculated per trip earning of 12910 NZM-BDTS Garibrath Express, It was around 21.5 lakh /Trip. Which is 87% earning of BCT Rajdhani. But we should consider operation cost of Rajdhani express which is relatively high because of food, bedroll and and Rajdhani type facility.
