Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 15, p. 65. See Locobase 16366 for a skeptical 1877 view of steam dummies and Locobase 11577 for a supporting 1889 discussion of the problems associated with running steam dummies on urban street railways. Works number was 9895 in March 1889.
See Locobase 11613 for a description of this Indiana street railway. Of the three steam dummies ordered from Baldwin by the ES & N in 1889, this pair had the smaller dimensions of the two designs.
Data from Baldwin Locomotive Works Specification for Engines, 1888, as digitized by the DeGolyer Library of Southern Methodist University Volume 15, p. 40. See Locobase 16366 for a skeptical 1877 view of steam dummies and Locobase 11577 for a supporting 1889 discussion of the problems associated with running steam dummies on urban street railways. Works number was 9895 in March 1889.
This street railway covered 12 miles and had as many as four locomotives and 12 passenger cars. This "dummy" was a locomotive sheathed in a car-like body that presumably didn't scare the horses as much. Despite the many criticisms of steam operations on city streets, the line proved surprisingly successful for more than 16 years, but the wisdom of converting the system to electric trolley operation proved incontrovertible in 1905.
See Locobase 11611 for the other two dummies Baldwin built for the ES&N in the same year.
