Steam dummy
 | This article needs additional citations for verification. (August 2016) |
A steam dummy or dummy engine, in the United States and Canada, was a steam locomotive enclosed in a wooden box structure made to resemble a passenger railroad car.[1] Steam dummies had some popularity in the first decades of railroading in the U.S., from the 1830s but passed from favor after the American Civil War.[dubious – discuss]
Overview
[edit]It was thought that the more familiar appearance of a coach presented by a steam dummy, as compared to a conventional steam locomotive, would be less likely to frighten horses when these trains had to operate in city streets.[2][3] Later it was realized that it was actually the noise and motion of the operating gear of a steam engine that frightened horses, rather than the unfamiliar outlines of a steam engine.
Production
[edit]
Baldwin Locomotive Works manufactured steam dummies or steam motors for many American tramways.[4] Baldwin exported to places such as Sydney, Australia – where they were known as 'steam tram motors' – and New Zealand, where two, both built in 1891, survive at museums today.
H. K. Porter, Inc. preferred the term "noiseless steam street motor" in their 20th-century catalog, although they used the term "dummy" (in quotes) in the 19th century. In the 20th century, they offered 0-4-0 and 0-4-2 wheel arrangements.[5] In the 19th century, they also offered a double-ended dummy with a 2-4-2 wheel arrangement.[6] Porter recommended using anthracite or coke as a fuel in order to avoid smoke. Side flaps to hide the mechanism were optional. Operating speeds between 15 and 25 miles per hour (24 and 40 km/h) were reported by 19th-century users.
In the UK, the Great Western Railway equipped two engines each from the 2021 and 517 classes with coach bodywork between 1906 and 1911.[7][8]
