These 70-Ton Barber S-2-A Roller Bearing Trucks have Spinning Spinning Brenco-3 Sided Bearing Caps with Semi-Scale Tread Nickel Plated 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 33″ “shiny” nickel plated all-metal semi-scale tread (.088″) wheels. (The same trucks with blackened normal tread .110″ wheels (SKU 416) and blackened semi-scale .088″ wheels (SKU 417) are also available.)
