HO-scale Lowboy booster kit

This 1/87 scale plastic model kit from Promotex provides two Lowboy Tri-Axle Booster assemblies for model-railway and diorama builders. Each set includes the booster unit, four wheel sets and integrated rear axle with fenders. The officially licensed replicas are moulded in true-to-scale detail and arrive in the manufacturer’s original unopened packaging. Simple assembly is required before the boosters can be placed on the layout.

Injection-moulded plastic construction

The boosters are produced in durable plastic with crisp moulding that captures prototype details at HO scale. Wheel diameter is approximately .5 inches, allowing the units to roll freely on standard HO track or display bases. Integrated rear axle and fenders are moulded as part of the booster body, reducing separate parts handling during assembly. The compact booster length of approximately three inches fits typical lowboy trailer decks without overhang.

1/87 scale compatibility

The model is engineered to 1/87 (HO) scale, so it matches rolling stock, structures and figures built to the same ratio. Builders working in other scales such as N or O will find the dimensions incompatible with their existing scenes. Collectors seeking a single booster rather than a twin pack should note this product only ships as two complete sets.

Questions about this item

What scale is this Lowboy Tri-Axle Booster model and how does it relate to standard HO track?

It is built to 1/87 scale, matching standard HO gauge dimensions so it sits correctly on HO layout track and alongside other HO rolling stock.

What are the physical dimensions of the booster and wheels to confirm it fits my diorama space?

The booster measures approximately 3 inches long and each wheel is about 0.5 inches in diameter, giving a compact footprint for tight scenes.

How do I assemble the two sets and which step is most often missed?

Snap the four wheel sets onto the integrated rear axle and attach the fenders; the step most often missed is fully seating each wheel onto the axle pins before clipping the fenders in place.
