Poland Spring 0-6-0 "Switcher" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 2 (Locobase 5308)

Data from Steamtown's Special History Study housed at [link] (visited 4 January 2003). Used Richardson balanced slide valves.Works number was 67536 in April 1927.

Although Hiram Ricker and Sons originally contracted for this saddle-tanker, it's unlikely that it ever actually operated for the mineral-water bottler in Maine. What is known is that its second owner -- EJ Lavino & Company -- procured it as their engine #3 to switch cars at the manganese blast furnace in Sheridan, Pennsylvania. In 1966, Lavino moved #3 to Bellows Falls, Vermont. It was later preserved by Steamtown in Vermont and moved with the rest of the collection to Pennsylvania.
