It supplies wheels for rolling-stock maintenance and manufactures steam locomotives for the Nilgiri Mountain and [[Darjeeling Himalayan Railway]]s. The wing includes a tool room and foundry, diesel component, machine, wheel, fabrication and smithy, erecting and mechanical [[millwright]] shops. The Mechanical Millwright Shop maintains machinery and equipment, including overhead cranes, material-handling equipment and other special-purpose machines. Over 1,200 pieces of machinery are installed at GOC. GOC uses the following for support activities: Golden Rock has three storage depots and a scrap-storage depot. Availability of material is 95 to 98 percent. The main goal of the plant maintenance team is to reduce machinery downtime. GOC's safety department, in existence for 30 years, uses training, drills, shop-floor counseling, data updating and the scientific elimination of work-related hazards. The department displays posters and safety magazines highlighting safety procedures, and develops a rapport with workers through customised safety modules. It received three awards from the [[government of Tamil Nadu]] in 2005. The shop has a training centre, primarily to offer courses in accordance with the Apprenticeship Act 1961. Training varies from one to two years, depending on entrance qualifications and the trade being taught. The centre also offers need-based training for artisans and supervisors. GOC has a fully equipped information system, required at the management and operational levels. It developed the Workshop Information System (WISE) in-house in 2001, implementing it the following year. Golden Rock assisted the [[Centre for Railway Information Systems]] in implementing WISE at 16 other railway workshops in 2004, and developed a Diesel Loco Maintenance Management Information System (DLMMIS). GOC has a Chemical and Metallurgical laboratory where quality analysis of materials procured by the stores are undergone. All employees contribute to (and are covered by) this social-security scheme, which gives to the family of a deceased employee. A [[Child care|crèche]], near the Armoury Gate entrance, cares for the children of workshop employees. A modern canteen, with a gas supply for steaming, caters to employees. Refreshments such as snacks, tea and coffee are supplied in work areas. The canteen has two dining halls, with a lunchtime capacity of 160. Tea and snacks are sold at nine booths. Schools were established for children of GOC employees before Indian independence. Although four schools and two [[kindergarten]]s once existed in Golden Rock's railway colony, its declining population has left only a single school.
