The "new" trucks are actually from an electric car order built for the Chicago Elevated and delivered in the early 1920s. The trucks were built by Baldwin (same builder of the Museum's locomotives 4012 & 4024), but are a decade newer than the trucks that would have been found under the 523 circa 1914. The front truck is powered with two GE traction motors and the rear truck is unpowered.
The Streetcar Investment Company purchased the trucks from a scrap car some years ago and the components had been in storage at their California yard. An industrial motor shop in the Bay Area overhauled the two GE 243 traction motors, and the Streetcar Investment folks reassembled everything. They arrived on a Gerlock Heavy Haul tow truck, the same rig that delivered 523 to the Museum more than two years ago.
The trucks are not ready for installation. It was important to acquire and move the trucks so that all the variables between the carbody and the trucks were correctly defined. Until they are installed, the trucks will remain in storage inside the Museum in Snoqualmie.
