HO Scale Pump Jack Counterbalance Weights
Pump jack counterbalance weights are a critical component of real-world pump jack and nodding donkey machinery, and including them in your freight operations adds a layer of mechanical realism that immediately elevates an oilfield scene. This HO scale load represents the kind of heavy industrial components commonly shipped by rail to support energy production across oil-producing regions.
Often referred to as nodding donkeys, sucker rod pumps, or pump jacks, these machines are a familiar sight across Texas, North Dakota, Oklahoma, and California. This load captures the supporting equipment that keeps those operations running, making it a natural companion to pump jack assemblies and oilfield-themed freight trains.
Each set includes two counterbalance weights mounted on a custom pallet, designed to represent realistic transport and storage conditions. The palletized format makes these loads versatile — they look equally at home secured to a flat car, staged in a yard, positioned in a workshop scene, or even displayed on a semi-truck trailer for intermodal or industrial highway scenes.
You receive two complete unpainted pallet loads, 3D printed in a light brown resin that is ready for painting and weathering. Whether you finish them as freshly manufactured components or heavily weathered, oil-stained machinery, the crisp detailing responds well to washes, dry brushing, and subtle highlighting.
Each pallet measures 2.13 inches long by 1.14 inches wide and 0.43 inches high (54 × 29 × 11 mm), making the loads well suited for typical HO scale flat cars. Photos show the loads displayed on a HO scale 50-foot flat car for reference only — the flat car is not included.
These counterbalance weight loads pair especially well with the HO scale pump jack / nodding donkey car load, allowing you to build a cohesive and believable oilfield freight consist.
This load is part of the wider ScaleRail3D HO scale range, which includes flat car loads, industrial details, and structures designed to bring realism and operational depth to HO scale model railroad layouts.

HO Scale Industrial Load – Frequently Asked Questions
What scale is this product?
This model is HO scale (1:87), designed to match standard HO scale freight cars and layouts. It is proportioned for realistic integration into industrial and heavy manufacturing scenes.
Is the flat car included?
No. This listing is for the industrial load only. Flat cars shown in photos are for display and scale reference purposes.
What flat cars does this load fit?
Designed to fit most HO scale 50’, 60’, and 65’ flat cars from manufacturers such as Athearn, Atlas, Walthers, Bachmann, and similar brands. Always review the product dimensions listed above to confirm compatibility with your specific model.
What material is this made from?
This HO scale industrial freight load is 3D printed using premium PLA filament. Select models use wood-fiber infused PLA to enhance surface texture for more realistic simulation when painted and weathered.
Does this come painted?
This version is supplied unpainted and ready for customization. It is ideal for modelers who prefer to apply their own paint and weathering techniques.
If you prefer a finished option, explore our Ready-to-Run pre-weathered range.
Is this suitable for a steel mill layout?
Yes. These HO scale steel mill car loads are designed specifically for heavy industrial scenes including steel mills, foundries, fabrication plants, power stations, and related industrial operations.
Are these loads prototypical?
Our designs are inspired by real-world heavy industrial transport practices. Dimensions and proportions are created to look accurate within HO scale (1:87) while maintaining durability for model railroad use.
Can I order a custom industrial load?
Yes. We regularly design custom 3D printed flat car loads for specific industries, layouts, and prototype inspirations. Contact us through ScaleRail3D.com to discuss your project.
