Locomotive builder

This is a list of locomotive builders by country, a work in progress including both current and historical builders.

Many locomotive builders changed names multiple times; the attempt is to give the most recognisable name, generally the one used for the longest time or during the company's best known period.

Generally, most locomotives for Australian railways were built from GE/EMD/Alco (United States) components, with the bodies built by Australian companies. Comeng, Clyde Engineering, and Goninan were the most prominent, building hundreds of locomotives for Queensland Rail, RailCorp (as the State Rail Authority), etc. Most of these companies have now merged to form the four listed below.

The Workshops below were part of New Zealand Railways.

Historically, major railways in the United Kingdom built the vast majority of their locomotives. Commercial locomotive builders were called upon when requirements exceeded the railway works' capacity, but these orders were generally to the railways' own designs. British commercial builders concentrated on industrial users, small railway systems, and to a large extent the export market. British-built locomotives were exported around the world, especially to the British Empire. With the almost total disappearance of British industrial railways, the shrinking of the export market and much reduced demand from Britain's railways, few British locomotive builders survive.
