what is 3e seat in train

The 3E seat in a train refers to the Third AC Economy class, which is a rare class available on some Duronto trains and Garib Rath Express trains in India. This class was introduced by Lalu Prasad Yadav to enable poor people to travel by AC coaches. The 3E class has 6 berths and 3 side-berths, making it a total of 9 berths per compartment. The extra side middle berth in 3E class makes it a bit congested during daytime journeys, while it is comfortable or rather manageable during night journeys. The facilities provided to passengers in 3E and the legacy AC coaches are largely similar with minor differences.
