Many passengers traveling in the scorching heat often look for a way to move from Sleeper class to AC. Indian Railways provides a facility where passengers can upgrade their travel class to get relief from the heat. This can be done either through the TTE on the train or via the automatic system during booking.
How to upgrade your ticket on the train
If you have a confirmed Sleeper class ticket and want to move to an AC coach, you must contact the TTE. If seats are available in the AC coach, the TTE will allow the upgrade after you pay the fare difference. For example, if a Sleeper ticket is ₹500 and AC 3-tier is ₹1,200, you pay the remaining ₹700. Traveling in AC without TTE permission can lead to penalties.
What is the Automatic Upgradation Scheme
The railways have a system that randomly upgrades full-fare passengers to a higher class for free. This happens during the first reservation chart preparation, usually four hours before the train leaves. To use this, passengers must select Consider for Auto Upgrade while booking. However, a Railway Board circular from May 13, 2025, clarified that Sleeper class tickets will no longer be upgraded directly to First AC.
New rules for class upgrades and booking
Railway Minister Ashwini Vaishnaw announced on March 24, 2026, that passengers can now upgrade their class up to 30 minutes before the train departs. This provides more flexibility than the old rules. Additionally, a new Passenger Reservation System is coming in August 2026 to improve booking speed and use AI for waitlist predictions.
