Why Choose HO Scale?

Why HO works for many model railroad layouts

HO scale is approximately 1:87 and offers a popular balance between realistic detail and manageable layout size. The scale is large enough to show locomotive, rolling stock, structure, and scenery details clearly while remaining compact enough for home layouts, shelf railroads, modular setups, and larger basement railroads. If you're comparing HO with other sizes, our Model Train Scales Explained guide explains the major model train scales and their differences.

The broad selection available in HO also makes it easier to shop around a specific railroad, era, manufacturer, or operating style. Buyers can build anything from a compact switching railroad to a large freight mainline, passenger operation, steam-era scene, or modern railroad using equipment from current and past production runs.

Buying HO Scale Trains

Choosing equipment, building layouts, and shopping new or pre-owned

Choosing HO Trains

HO locomotives and rolling stock form the operating core of a model railroad. Depending on inventory, shoppers can find diesel, steam, and electric locomotives, freight cars, passenger cars, specialty equipment, and complete train sets. When choosing equipment, consider the road name, era, locomotive type, condition, and operating requirements. Train sets may include a locomotive, cars, track, and controls, or may contain only the train; review each listing for what is included.

Building an HO Railroad

HO track is offered in sectional, flex, and integrated-roadbed systems, with different rail codes, curve radii, turnout styles, and connections. Matching an existing track system can simplify expansion. Buildings, figures, vehicles, scenery, and accessories help complete a layout, while replacement parts such as couplers, wheels, trucks, and locomotive components can support repairs and restoration.

Buying New & Pre-Owned HO Trains

HO locomotives may use conventional DC, be DCC-ready, or have factory-installed DCC decoders; some offer sound and lighting features. Check each listing for control system, decoder status, minimum curve requirements, and compatibility. Trainz inventory may include factory-new, pre-owned, vintage, collectible, discontinued, new old stock, limited-release, and hard-to-find HO trains. Availability changes as collections and new inventory arrive.

HO Scale Train Questions

Answers to common HO model railroad questions

What does HO scale mean?

HO scale is approximately 1:87, meaning the model is about 1/87th the size of its full-size prototype.

What types of HO trains can I buy?

HO trains include diesel, steam, and electric locomotives, freight cars, passenger cars, motorized units, operating cars, rail transit equipment, and complete train sets. HO railroads can also use scale-specific track, structures, accessories, scenery, and replacement parts.

Are HO trains good for beginners?

Yes. HO offers a broad selection of starter train sets, track systems, locomotives, rolling stock, replacement parts, structures, scenery, and accessories, making it practical for a first railroad while still offering substantial options for experienced modelers.

Can HO trains from different manufacturers run together?

Often, yes, but compatibility can depend on the track and electrical system, coupler type, wheelsets, minimum curve requirements, and the age or design of the equipment. Review individual product specifications when combining models from different manufacturers.

What should I consider when choosing HO track?

Consider whether you are building a new railroad or matching an existing track system, along with rail code, curve radius, connection style, roadbed design, turnout geometry, and the type of layout you plan to build.

What is the difference between DC and DCC?

DC generally controls locomotive speed by varying power supplied through the track. DCC sends digital commands to equipped locomotives and can provide independent locomotive control along with features such as sound and lighting.

Can standard HO trains run on HOn3 or HOn30 track?

No. HO, HOn3, and HOn30 models may share approximately 1:87 scale proportions, but they use different track gauges and are not directly interchangeable on the same track.

Does Trainz sell vintage and discontinued HO trains?

Yes. Depending on current inventory, Trainz may offer vintage, pre-owned, discontinued, collectible, estate-find, and hard-to-find HO locomotives, cars, train sets, track, and other model railroad equipment.
