The SAL owned 170 mikes and 117 were Q3 class. The Q3s had air pumps mounted on the face of the smoke box.
It had a 4 axle Vanderbilt tender with a Franklin booster on the tender. The tenders carried 17 tons of coal and 9600 gals of water. The Q3 also had Baker valve gear. This engine type had automatic stokers and was Seaboard's "signature" steam loco:
Basically a USRA Light copy.
How can anybody ignore the beautiful mug on that beast
Has there been an O-scale model made of any engine that had a Franklin booster?
