The first carriages built by the workshops were completed in 1889, but early locomotives were manufactured by external contractors such as the Phoenix Foundry in Ballarat.
During World War II the workshops were turned over to military production, with the rear fuselage, and empennage of Bristol Beaufort bombers being built there.
[1] In the late 1980's, the original segments of the workshops were removed from everyday use, with operations continuing at the 1930s complex along the eastern side of the site.
[6] On 15 January 2000, operation of the workshops and ownership of assets passed from the Public Transport Corporation to Evans Deakin Industries (EDI, formerly Clyde Engineering).
From 2018 - 2024, High Capacity Metro Trains (HCMT) were constructed at Newport by Evolution Rail in part of the former Boiler Shop.
