These coaches, officials said, will be “economical” and in between the current AC three-tier and non-AC sleeper class.
It was conceived by RCF and work on its design started on war footing in October 2020. The new coach can carry more passengers as the berths have been increased from 72 to 83.
“Many innovations have been incorporated in the design of the coach. The high voltage electric switchgear presently installed on board has been shifted below the under frame, thereby increasing the passenger capacity by introducing 11 additional berths,” a statement from the ministry said.
Each coach is provided with a wider and one disabled friendly toilet entry door which is a new initiative, it said.
Several design improvements have also been made for improving passenger comfort like redesigning the AC ducting to provide individual vents for each berth, it said.
The coach also has improved and modular design of seats and berths, foldable snack tables in both longitudinal and transverse bays, injury free spaces and holders for water bottles, mobile phone and magazines, it said.
Individual reading lights and mobile charging points are provided for each berth in addition to the standard socket.
A new ergonomically improved design of ladder for accessing the middle and upper berths is also a new feature. There is an increased headroom in the middle and upper berths as well.
The design has been improved for both Indian and the Western style lavatories while public address and passenger information systems have been installed as part of passenger facilities, it said.
“Ambience and ease of access into coach has been improved by aesthetically pleasing and ergonomic entrance. The interior of the coach has luminescent aisle markers, illuminated berth indicators integral with night lights with luminescent berth numbers,” the statement said.
“There is also improved fire safety by ensuring compliance to world benchmark of EN45545-2 HL3 for materials, thus meeting the high requirements of the new fire protection standard,” it said.
The RCF has production plan of 248 such coaches during the current and next fiscal.
“Series production of these coaches will be started from this month. This new 3-tier air conditioned economy class coach is a symbol of aspirational India bringing AC travel to larger number of people and enhancing the capacity of our express trains. Undoubtedly, now every rail journey will become a journey of pleasant memories,” the statement said.
