This section includes all of the castings needed to build the trucks. The quantities are defaulted to the amount needed to build a three truck shay.
The trucks are fabricated using the listed castings along with various shapes of hot rolled steel bar and angle. The gears are stock gears which are manufactured by either Boston Gear or Martin Gear. The axles run on ball bearings while the drive shaft runs in bronze bushings. The drawings cover the machining of the truck castings along with the other components needed to complete the trucks. The brakes are steam actuated and there are drawings covering the brake system.
