"The design, assembly and packaging quality of Arrowhead’s Definitive HO Scale Wheelsets goes beyond anything the industry has seen previously."

Philip Smith, railroad engineer and prototype modeler


By building a better wheel, Arrowhead Models brings to market unmatched part fidelity, performance enhancements, and we open the door to new opportunities in prototype modeling.

The Definitive HO Scale Wheelset is precision-machined with accurate contoured surfaces. The wheels have meticulously crafted anterior and posterior faces and offsets. The axle is prototypically dished. The wheelsets are electrically insulated and meet NMRA standards for Code 88 tread profiles and gauge.

Both wheels and axles are cut from high grade nickel silver stock. They are milled from state-of-the-art CNC Swiss lathes by professionals who deal in high tolerance, speciality projects. Nickel silver is a hard alloy with a naturally polished finish--which makes it perfect for replicating the shiny treads of in-service cars. It is our preferred material for wheelsets because it and its oxides are electrically conductive, the material is nonmagnetic, and it has a high resistance to corrosion. And, believe it or not, its natural color is remarkably accurate match to the finished surfaces of new wheelsets among the prototype. (Although, they don’t stay that color for long, and we don’t expect yours to either.)

Furthermore, every wheelset is subject to tests that ensure the wheels and axles are tight, true and in gauge.

Finally, Arrowhead’s wheelset are individually cradled in clam-shell packaging. In this way, axle tips remain sharp and the precision edges that we have worked hard to create don’t mar in the packaging--an outcome not uncommon to bulk alternatives.
