The Anacortes Railway was founded in 1965 when Tommy and Anne Thompson purchased No. 22, a 3.5 ton compressed air locomotive from the Homestake Mining Co. in Lead, South Dakota. After shipping to Anacortes, the Railway's backyard foundry and machine shop transformed the 0-4-0 to a 0-4-4 Forney Type steam locomotive. Seattle Boiler Works constructed the all-welded ASME boiler, which has a working pressure of 150 psi and is fired with fir bark. It took Thomas G. Thompson, Jr., the builder, 1700 hours over a period of five years to complete the 4.5 ton engine. Thanks to the AT&R webpage for this information.
