The bathrooms have both western and Indian style toilets. Fans on the carriage ceiling provide some cooling, and the windows have bars to keep intruders out as they are usually kept open. Two tiers of beds are also located outside the compartments, along the aisle. During the day, the middle beds must be folded down flat against the compartment walls to allow passengers to sit on the lower beds. The beds are stacked vertically in three tiers on either side of the compartments. The carriages are divided into open-plan compartments with six beds in each. These days, you'll often find people from General Class (who were unable to get confirmed tickets) flooding over into the Sleeper Class carriages. While most of India's middle class used to travel in Sleeper Class, many have now moved up to AC 3.
