articulated driving wheel trucks, all having cast
steel frames furnished by General Steel Castings
Corporation. The articulated trucks have side
frames, crossties, pedestals, engine truck center
pins, cab center plates and motor suspension
supports cast integral. The frame pedestals are
equipped with rubber insert pedestal gibs. The
inner ends of the two articulated truck frames are
connected by means of an articulated joint of the
ball, socket and pin type, oil lubricated. The mo-

Driving axles are of forged low-carbon nickel-
steel, hollow-bored and mounted in SKF roller
bearings. The multiple-wear driving wheels, 40
inches in diameter, are "Freedom" type wrought
steel furnished by Standard Steel Works Division
of Baldwin. The roller-bearing boxes are arranged
for oil lubrication of bearings and pedestals, and are
designed for future application of the Edison
bearing temperature alarm system.
Equalization for each articulated truck consists
of a three-point support with four driving axles
connected together on the side forming two points,
while the third point is the engine truck center
pin. A semi-elliptic spring rests directly on each
driving box, the ends being connected to forged
equalizing beams except at the ends where
spring-cushioned links connect the system to the
articulated truck frame.
The four-wheel engine trucks (leading and
rear) have hollow-bored axles of low-carbon
nickel-steel, mounted in SKF roller bearings.
"Freedom" wrought steel multiple-wear wheels,
40 inches in diameter, are used under the trucks.
The nickel-steel frames have side members, tran-
