Indian Railways on Wednesday said that it will introduce flexi fare pricing on its Rajdhani, Duranto and Shatabdi trains from September 9.

"The base fares will increase by 10 per cent with every 10 per cent of berths sold subject to a prescribed ceiling limit. There will be no change in the existing fare for 1AC and EC class of travel," a railway ministry release said. 

According to a release by the Railways, while booking if the price of a ticket is higher than the price of the next class, passengers would be informed of the same.

The dynamic pricing won’t include additional charges viz. Reservation, Superfast, Catering, Service tax.

However, persons who have booked their tickets before Wednesday’s announcement won’t have to pay more.

Unclaimed berths will be sold at the last recorded price and the same would be printed on the reservation chart.

Instead of Tatkal charges, seats under Tatkal quota would be charged 1.5 times the base fare in addition to reservation fee, superfast charges, catering charges, service tax.
