Steam Machines, Engines, Locomotives. In 1781 James Watt patented a steam engine that produced continuous rotary motion. Watt's ten-horsepower engines enabled a wide range of manufacturing machinery to be powered. The engines could be sited anywhere that water and coal or wood fuel could be obtained. By 1883, engines that could provide 10,000 hp had become feasible. The steam engine was one of the most important technologies of the Industrial Revolution.

This image dataset is generated from our world's largest public domain image database. Made in two steps (manual, and image recognition), it comprises of more than 35,000 images of all types and sizes - an astonishing number if keep in mind that the total number of steam locomotives ever built was just one order of magnitude larger. All images are in the public domain, so there is no limitation on the dataset usage - educational, scientific, or commercial. Please contact us if you need a dataset like this, we may already have it, or, we can make one for you, often in 24 hours or less.
