For some time now, the Indian Railways has been introducing AC coaches in trains by replacing either Sleeper or Second-Class coaches. In May, in four pairs of trains operating out of Mangaluru Central Railway Station, one Sleeper Coach each was replaced by an AC 3-tier Economy Class coach each. In September, in Bagmati Superfast Express, Rapti Sagar Superfast Express and Muzaffarpur Express, an AC 3-tier Economy Class coach was introduced in place of a general Second Class coach each.
These changes have serious implications as the probability of travellers reserving a ticket in Sleeper and Second Classes has come down, forcing them to either upgrade to AC coaches or make alternative travel plans. Those holding an unreserved ticket to travel in General Coaches also may find it tough to get seats. With a relatively smaller share of people able to afford the higher costs of AC coaches, and in scenarios where alternative arrangements are not possible, incidents of general ticket holders invading reserved compartments have become common.
A comparison of passengers carried in 2019-20 and a decade back in 2009-10, shows that the above examples are not exceptions but the norm.
