Notes for ALCO trucks
c/c trks for all 2 axle trucks are the dimension from center of one truck to the center of the other truck, not the jacking pads or truck bolsters.

c/c trucks for 3 axle trucks are the dimension from one bolster to the other bolster. Bolster is the pivot point of the trucks.

This data is for units as delivered from the manufacturers.

Always refer to pictures of the unit to be modeled as many trucks are interchangeable.
The trucks were sometimes swapped by the Railroads or rebuilders.
