This section lists HO scale lost-wax brass detail parts for diesel locomotives, covering horns, sand hatches, ice breakers, winter hatches, and air intake grills. The parts are cast in brass and require cleaning of any residual investment material from the castings, usually by filing or scraping with a sharp blade. Most parts are designed to be glued in place with cyanoacrylate or epoxy after the locomotive body has been painted and prepared. The horns, such as the K3, M3, Leslie, and 5-chime types, are typically mounted on the roof or hood of the locomotive, and you may need to drill a small locating hole for the horn base. The sand hatches and winter hatches are surface-mounted details, so they can be positioned directly on the body after removing any raised detail with a file. These parts are suitable for a variety of HO diesel models, including EMD, Alco, and GE units, and can be used to upgrade ready-to-run models or add detail to kitbuilt locomotives.

The parts in this section are intended for HO scale (1:87) models, and they represent common details found on North American diesel locomotives from the 1950s through the 1980s. The horns, for example, are typical of those used on EMD, Alco, and GE road switchers and road units. The sand hatches are designed to fit the specific shapes of RS2, RS18, SD50, and other models, so you should check the prototype photo or drawing to confirm the correct placement. The ice breakers and winter hatches are often seen on locomotives assigned to cold-weather service, and they can be added to models of F units or other hood units. When fitting these parts, it is advisable to test-fit them dry before applying adhesive, and to use a small amount of gap-filling CA if the part does not sit perfectly flush. The brass parts can be painted with a primer before final painting, but if you prefer a bare metal look, you can polish them with fine abrasive paper.

This catalogue section is a reference for the range of detail parts available from this workshop. Each item is listed with its number and description, and the parts are grouped by type for easy browsing. The lost-wax brass castings are produced to a consistent standard, and they are suitable for modellers who wish to enhance the appearance of their HO locomotives with accurate, fine-scale details. The parts are not specific to any particular manufacturer's model, so you may need to adapt them slightly to fit your chosen locomotive. For example, the horn brackets may need to be trimmed to match the contour of the roof, and the sand hatches may require a small amount of sanding to fit the hatch opening. The winter hatches are designed to cover the dynamic brake hatch or other roof openings, and they can be glued in place to represent a winterization hatch. The air intake grill is a surface detail that can be applied to the side of an SW or other switcher model. All parts are small, so handle them with tweezers and use a magnifying lamp if needed.
