The 25 Big Boy locomotives were built to haul freight over the Wasatch Range between Ogden, Utah, and Green ...
Most Locomobiles had simple twin-cylinder engines (3x4 in, 76.2x102 mm; 57 in 3, 927 cm 3) and a wire-wrapped 300-psi boiler, and burned the liquid fuel naphtha to create steam. Typical of the product was the 1904 Runabout, which seated two passengers and sold for $750 [ 4 ] : 854 (equivalent to $25,433 in 2023).
The PRR S1 class steam locomotive (nicknamed "The Big Engine") was a single experimental duplex locomotive of the Pennsylvania Railroad. It was designed to demonstrate the advantages of duplex drives espoused by Baldwin Chief Engineer Ralph P. Johnson. [1] The streamlined Art Deco styled shell of the locomotive was designed by Raymond Loewy. [1 ...
The first experimental steam-powered cars were built in the 18th and 19th centuries, but it was not until after Richard Trevithick had developed the use of high-pressure steam around 1800 that mobile steam engines became a practical proposition. By the 1850s there was a flurry of new steam car manufacturers.
The club was founded in 1957 to promote the restoration and safe use of steam-powered automobiles. [3] Since that time its mandate has grown to become a source of information on modern light steam power, including historic automobiles, new steam autos and small steam plants for alternative energy applications.

Each set of driving wheels is driven by two steam cylinders. In essence, the result is two engines under one boiler. Union Pacific developed five types of Challengers: the "light" CSA-1 and CSA-2 classes and the "heavy" 4664–3, 4664–4, and 4664-5 classes. The railroad sought powerful locomotives that could handle mountain grades at high speeds.
