what is 3e in train booking

The 3E class in train booking refers to the Third Class Economy or Third Class AC Economy. It is a class of travel in Indian Railways that is one step below the Third Class AC (3A) and one step above the Sleeper Class (SL) . The 3E class is an air-conditioned class of travel that provides basic amenities such as a berth, bedding, and curtains for privacy. However, it does not provide the same level of comfort as the higher classes of travel. For the 3E class of some trains, no extra bedroll is provided.
