Suvidha Express trains were primarily launched by the Indian Railways as a means to ease the ever increasing burden on the existing trains and to provide passengers with comfortable and convenient long distance travel. Several of the premium trains with fully air-conditioned coaches and super fast speed also come under the Suvidha category. The Suvidha trains have some special features that distinguish them from other trains. The fare for these trains is higher than that of normal trains. The minimum fare is in the same range of Tatkal fare for the particular class while the maximum fare may be up to three times of Tatkal fare. Only confirmed and RAC tickets will be issued on these trains, and cancellation of the tickets is also not permitted. Unlike many other trains, in Suvidha trains, there are no concessions/discounted fares for children and senior citizens. AII HWH Suvidha, NJP HWH Suvidha, and BCT LKO Suvidha are some trains in this category.
