Custom designed O scale 16-axle heavy duty flat car.
I have built a heavy duty 16-axle flatcar based on a prototype car manufactured by National Steel Car Company. It uses 8 pair of MTH roller bearing trucks with an articulated bolster which allows additional lateral movement of the trucks.
The prototype NSC car has 12 axles as shown in the attachment.
My O scale car has a scale wheelbase of 86-1/2 feet and an overall length of 92-1/2 feet. The truck bolsters on the model are specially designed to allow operation on small radius track. The "pivot" points for the car bed are located so that the actual "overhang" on curves is minimized. The car pivot points are actually 11 inches apart. This is about the equivalent of a 50 foot boxcar. This car will actually "snake' through a series of curves and turnouts since each truck bolster pivots independently.
Model photos shown.
The NSC prototype as shown is listed as an 89 foot car.
