The new class coach can carry 83 passengers as against 72 persons in conventional 3 tier AC coaches. “Electrical switch gears had been shifted to under slung, thereby providing space for 11 berths additionally,” said sources.
Unlike conventional AC coaches, the new coaches had been designed to provide enhanced passenger comfort such as AC ducting to provide individual vents for all berths.
