The Mumbai-Delhi superfast is already generating good revenue for the Western Railways (WR). The premium special AC train has earned them Rs 1 lakh more than what they normally do from their most elite train, Rajdhani Express.

According to WR officials, this 17-coach train earned them Rs 23.40 lakh on its maiden trip to Delhi on December 26 while, on the other hand, the Rajdhani Express generates Rs 22.40 lakh after all seats are sold out. The simple reason for this additional revenue is the economics of running the premium train, which is similar to that of an airline -- the fare of each seat depends on the demand.
