4-4-0 "American" Steam Locomotives in the USA

Ligonier Valley


Class Details by Steve Llanso of Sweat House Media

Class 17 (Locobase 13932)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 51, p. 317. Works number was 41306 in April 1914.

Although a short short line, the LVRR carried 9 million passengers, most of them headed to Idlewild Park in the Mountain Playground of western Pennsylvania. This design was well-suited to the short-haul, many-stop service required for such a line.

Three years after the first Brill gas-mechanical "doodlebug"came on the property in 1929, however, the 17 was retired in 1932.
