The ICF was established in 1952 and started production on 2 October 1955. The first items produced were third class shells for Southern Railway.


The ICF consists of two main divisions, namely, shell division and furnishing division. The shell division manufactures the skeleton of the rail coach, while the furnishing division is concerned with the coach interiors and amenities. An ancillary unit to the ICF is being built in Haldia, West Bengal for furnishing diesel multiple units.[5] ICF manufactures more than 170 varieties of coach including the kolkatta metro rakes for bhel,ngef,cnrdalian icf/medha first and second class coaches, pantry and kitchen cars, luggage and brake vans, self-propelled coaches, electric (EMU), diesel (DMU) and mainline electric multiple unit (MEMU), metro coaches and diesel electric tower cars, accident relief medical vans (ARMV), inspection cars (RA), fuel test cars, track recording cars and luxury coaches. The plant employs about 11,095 people and manufactures about 2000 coaches per year. ICF churned out 1,503 coaches in 2010[6] and in August 2011, ICF was sanctioned a project for manufacturing stainless steel shells and high speed bogies and an increase in capacity from 1,500 to 1,700 coaches.[6] In 2013-14, it built 25 LHB Coaches, 248 air-conditioned and 1185 non-AC coaches.[7] It plans to increase its manufacturing capacity of LHB coaches. It has set a target to manufacture 300 LHB coaches in 2014-15 and reach a capacity of 1000 LHB coaches by 2016-17. ICF has turned out a record outturn of 2277 coaches during the year 2016-17 consisting of more than 50 variants involving high technological inputs, meticulous planning and execution.[8] A total of 50,000 coaches had been produced till 18 Aug 2015 by ICF since its inception. On an average, the ICF takes 20 days to build a coach.[9]

In October 2018, ICF Chennai began testing Train 18, a long-haul passenger EMU. ICF will also manufacture MEMU potential to operate at 110/130 km/hr whose trials are expected in February 2019 for Northern India.

A Regional Railway Museum is situated in the factory premises. It has a collection of nascent models of trains and models endemic to the Indian Railways. About 59.1 million units of electricity had been generated through the windmills installed by ICF in Tirunelveli district in 2011 which met 80 percent of the plant's electrical energy requirements.[10][11][12]


The air-conditioned train-sets manufactured by ICF for Kolkata Metro allegedly broke down causing disruption of services. According to newspaper reports, the air-conditioned rakes have been sent to Kolkata without conducting dry runs because the ICF does not have third rail testing facilities.[13][14][15][16][17][18][19][20][21][22]
