RailFans - हमको देख देख दुनिया जले, हमको ज़माने से क्या

The aim and objective of introducing trains with dynamic fares is to provide rail-users the facility of travelling at short notice by paying higher fares during specific periods when there is heavy rush.
The travelers have the option of travelling in regular Mail/Express and passenger trains by paying the normal fare. Indian Railways caters to various segments of the travelling public and accordingly operate different types of services like suburban services, passenger services and Mail/Express services, which include Rajdhani, Shatabdi, Duronto, Yuva and Garib Rath services etc. Running of Suvidha Trains (earlier, premium trains) during peak seasons do not displace these regular services but complement them by providing a facility for travel at short notice by paying higher fares.

effect from 01.07.2015, Suvidha trains (in place of Premium trains) have been introduced for meeting demand peaks as do arise from time to time during summer, winter, festivals and on other occasions. The features of Suvidha Trains include facility to book tickets at Passenger Reservation System (PRS) counters as well as through internet, rationalized fare structure, provision for refund as permissible on cancellation of ticket etc. Minimum fare of Suvidha trains is equal to tatkal fare applicable for the class of accommodation for initial 20% of the berths and thereafter the fare increases for subsequent slabs of 20% of seats/berths booked subject to maximum of three times of Tatkal fare. Other applicable supplementary charges like reservation charge, superfast charge, service tax etc. are levied separately.
The service has been provided with a view to supplement facilities regularly available to passengers through a mechanism that caters to the requirement for that segment of passengers which is willing to travel at short notice by paying higher fare.
