Roanoke Street Railway 0-4-2 Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class Leila (Locobase 11625)

Data from Baldwin Locomotive Works Specification for Engines, 1888, as digitized by the DeGolyer Library of Southern Methodist University Vol 15, p. 91. Works numbers were 10024-10025 in June 1889.

Little Leila and Carrie were two more examples of the steam "dummies" that Baldwin was supplying to street railways across the country. When the RSR was electrified in 1892, Leila was sold to Eureka Lumber Company.
