The proposed fully AC train will have three-tier Economy AC coaches besides AC-3, AC-2 and AC-1 classes as part of the transformation exercise. However, the passengers will not require blanets in the Economy AC class like other AC coaches as the temperature will be around 24-25 degrees. Currently Mail and Express trains have Sleeper, Third AC, Second AC and First AC classes while Rajdhani, Shatabdi and recently introduced Humsafar and Tejas trains are fully air-conditioned. The railways is exploring an idea to introduce fully AC trains in select routes, aiming to provide comfort by facilitating AC travel for maximum passengers. The fully AC train with more Economy AC coaches is expected to cater to more passengers.
