When an existing railroad already uses a named track system, buying matching components is generally the easiest way to preserve its roadbed height, connection style, curve geometry, and finished appearance. Use the system pages below to find more focused selections of HO replacement track and expansion pieces.

If you are replacing only one piece, compare the product number, section length, curve radius, turnout direction, and connector style before ordering. Similar-looking track from different systems may not connect directly.

Rail code refers to rail height and is an important buying detail when matching track already installed on a layout. Using the same code helps maintain consistent rail height, while transition joiners or careful roadbed adjustments may be needed when combining different codes.

When buying replacement HO sectional track, check both the rail code and the manufacturer. Two sections with the same code can still use different tie dimensions, geometry, joiners, or roadbed designs.

Most HO track purchases fall into one of two categories: expanding an existing layout or building a brand-new railroad. If you're adding to a layout you already own, matching the same manufacturer, track system, and rail code is usually the simplest way to ensure compatible connections and dependable operation.

For a new layout, think about how you plan to build. Sectional track makes planning straightforward with fixed lengths and curve radii, while flex track allows broader curves and more realistic track arrangements. Roadbed track systems offer fast assembly for temporary, modular, or beginner layouts, while traditional track is often preferred for permanent railroads with custom scenery and ballast.

Beyond the track itself, many layouts eventually require feeder sections, rail joiners, insulated joiners, switches, crossings, and power connections as the railroad grows. Planning for future expansion today can make adding new sidings, industries, and yards much easier later.

Whether you're replacing a damaged turnout, searching for a discontinued curve, or completing a layout that has been sitting unfinished for years, Trainz regularly offers HO replacement track in both new and pre-owned condition. Inventory changes frequently and may include complete track lots, individual sections, estate finds, vintage components, and hard-to-find pieces from many of the hobby's leading manufacturers.

Before ordering replacement HO track, compare the manufacturer, product line, rail code, section length, curve radius, and part number whenever possible. Taking a few extra minutes to match these details can help ensure the new track fits seamlessly into your existing railroad.

Where can I buy HO Scale track?

Trainz regularly offers HO Scale track for sale in new, used, pre-owned, vintage, discontinued, and hard-to-find condition from many of the hobby's leading manufacturers.

Which HO track system should I buy?

If you're expanding an existing layout, matching the same track system already in use is usually the best choice. For a new railroad, consider whether you prefer roadbed track, sectional track, or flex track based on your layout goals.

Should I buy sectional track or flex track?

Sectional track uses fixed geometry for quick planning and assembly, while flex track allows custom curves and more realistic track arrangements for permanent layouts.

What HO rail code should I choose?

Code 83 is a popular choice for modern layouts, Code 100 remains common for durability and older equipment, while Code 70 and Code 75 are often selected for lighter branch lines and more prototypical appearance.

Can different HO track brands or rail codes work together?

Some traditional HO track brands and rail codes can be combined with compatible joiners or transition pieces, but rail height, geometry, roadbed design, and connection style should always be checked first.

Does Trainz sell new and used HO replacement track?
