It should be noted by all the passengers that when their ticket is booked under the tatkal category the cancellation charges vary from the normal quota as the tatkal quota is a special kind of quota available to the passengers for booking of the railway ticket. A penalty of 25% from the total cost of the tickets that has been booked is normally levied by the railway authorities. Normally the railway authorities do not encourage for any refund of the amount if the cancellation of the tickets under the tatkal category is carried out by the passengers within 24 hours of the departure of the train. There are separate charges that are levied by the railway authorities for cancellation that is contingent and for tatkal tickets that are wait listed. For detailed charges on the various cancellation levied by the railway authorities under the different quota the passengers can browse the website of the Indian Railway Reservation to understand all the cancellation charges.
