The '''Golden Rock Railway Workshop'''  (officially the Central Workshop, Golden Rock, abbreviated GOC), in Ponmalai (Golden Rock), [[Tiruchirappalli]], [[Tamil Nadu]], is one of three railway workshops serving [[Indian Railways]]' [[Southern Railway zone]]. The workshop is part of the railways' Mechanical Department. The other two Southern Railway workshops (Carriage Works and Loco Works) are in [[Perambur]], Chennai.{{efn|The [[Integral Coach Factory]] in Perambur, a production unit, is not a workshop; workshops primarily perform repair and maintenance work, not production. Due to changing requirements, however, many workshops (including Golden Rock) are now also used for production.}}

== History ==
[[File:North 'D' entrance of Railway Workshop.JPG|thumb|alt=See caption|Branch shops on both sides of the north entrance, connected by a transfer table]]
This central workshop was set up in 1897 by [[South Indian Railway Company|South Indian Railways]] at [[Nagapattinam]] to maintain steam locomotives. South Indian Railways decided to move the workshop to Trichinopoly (present-day [[Tiruchirappalli]]) because of its better location. The [[Cornerstone|foundation stone]] of the Tiruchchirappalli workshop was laid by Mrs. R.P. Munro on 20 December 1926, and work was completed in 1928. 

The workshop had state-of-the-art facilities, including a powerhouse which generated electricity for the workshop and the colony. Golden Rock's railway colony was one of Tiruchirappalli's first locations with electric lighting. The workshop repaired [[Royal Air Force]] planes during [[World War II]].

The workshop covers about {{convert|200|acre|ha}}, of which {{convert|26|acre|ha}} is under cover. It has a {{convert|600|m|yd|adj=mid|-long}}, {{convert|80|ft|m|adj=mid|-wide}} [[transfer table]]. 

In 2018, Golden Rock had 6,091 employees. The workshop primarily maintains [[Passenger car (rail)|coaches]] and diesel and heritage steam locomotives and manufactures [[Railroad car|wagons]].
