I couldn't able to understand sometimes even 22221/22222Rajdhani fare is lesser than LTT HW AC Superfast between Mumbai to Bhopal. (actually it was due to dynamic pricing but AC SF don't have dynamic fare system) . Also Why there is fare difference between of 3A of LTT LKO AC SF and LTT HW AC SF between Mumbai and Bhopal although both are AC SF category and both have same facilities (Pantry car, E catering etc).I couldn't able to understand this. Please explain this anyone.
