Chullora Railway Workshops were a major workshops for the repair and heavy maintenance of locomotives and rolling stock for the New South Wales Government Railways.
It was built on site at Chullora over 485 acres adjoining the main Sydney marshalling yards at Enfield. The decision to build a new workshop was made because of the inadequacy of the existing facilities at Eveleigh Railway Workshops and the decision to electrify the Sydney metropolitan network.[1]
The master plan envisaged it would cover all aspects of railway operation with separate facilities for a locomotive workshop, carriage workshop, wagon repair depot, electric repair shop, signal engineers branch, general railway store, water supply and existing lines branch.[1]
