These 100-Ton Barber S-2 Roller Bearing Trucks have Spinning Timken Bearing Caps with Normal Tread All-Metal Precision Wheelsets. An all-new truck offering for Tangent Scale Models, this truck comes with a separate brake beam part for body mounted brakes so that the brake shoes will be close to the wheels, just like the prototype.  These BLACK trucks are equipped with 36″ blackened all-metal normal tread (.110″)
