I used to take this Raj regularly between SBC and SC, and while I used to get tickets comfortably most of the time, the train always seemed quite full every time at SBC, with a good chunk of people boarding from SC too, for the on-ward journey. But then, my journeys were mostly on the weekends and long before the flexi-fares were implemented, so it may no longer be a valid impression. But at least until a couple of years ago, it was definitely not a Flop train.
