This list of locomotive builders is ordered by country and includes current and defunct builders. Many of the companies changed names over time; this list attempts to give the most recognisable name, generally the one used for the longest time or during the company's best-known period.
Category for manufacturers of steam engines – that is, stationary steam engines and marine steam engines. (Manufacturers of steam railway locomotives (often known colloquially as steam engines) are listed elsewhere.)
Baldwin also produced their most powerful steam engines in history, the 2-8-8-4 "Yellowstone" for the Duluth, Missabe & Iron Range Railway. The Yellowstone could put down over 140,000 lbf (622.8 kN) of Tractive force. They routinely hauled 180 car trains weighing over 18,000 short tons (16,071 long tons; 16,329 t).
The East African Railways 4-8-2+2-8-4 59 class Garratts were the largest and most powerful steam locomotives to run on metre gauge, having a large 70-square-foot (6.5-square-metre) grate and a tractive effort of 83,350 pounds-force (370.76 kilonewtons). The 34 oil-fired locomotives remained in regular service until 1980.
There were a large number of manufacturers in Great Britain. Most started life as agricultural engineers, and many exported engines all over the world.

They hope to use it as a platform for developing "the world's cleanest, most powerful passenger locomotive", capable of speeds up to 130 mph (210 km/h). Named "Project 130", it aims to break the world steam-train speed record set by LNER Class A4 4468 Mallard in the UK at 126 mph (203 km/h).
