Protocraft was established in 1994 as a company designed specifically to provide the O scale model Railroad enthusiast with accurately scaled components to complete the otherwise fine O scale models available. With new O scale models being brought in every day, hundreds of fine O scale models that were made in both Japan and Korea years ago, and now in China, readily available at both trade shows and over the internet, there exists a wide range of opportunities and needs for the modeler who desires and appreciates an accurately scaled model. Achieving this goal is now possible with the many finescale components now available.

Protocraft’s emphasis is on wheels, but it also provides trucks, diesel conversion kits, steam locomotive tires, the only finescale working coupler available, rail, and many of the tools necessary to accomplish various conversions from O Scale to Finescale, also known as Proto:48.

The principal behind Protocraft is always build everything at 1:48 from the prototype drawings, and not only will it look realistic, the parts will work and they will be interchangeable, just as much as parts work and are interchangeable in the real railroads.

Protocraft is not alone in developing and producing finescale components. It has patterns made by well known artists such as Oscar Newbert and Bill Clouser, tools designed by Paul Martineau, diesel conversion patterns by Pat Mitchell, and many different wheels and stampings designed by Steve Grabowski

Many HO modelers have shifted to a larger scale in order to achieve a more detailed and realistic operating model because it’s much easier to detail, view, and has significantly better operating characteristics. O Scale is the natural choice for these modelers. Protocraft presents a further option - that of 1/4 inch finescale/Proto:48.
