Z Scale Track

Z Scale track uses a 6.5mm gauge for 1:220 model trains, and its small size is one of the reasons modelers choose Z Scale in the first place. A compact tabletop can hold more than a basic loop, while a larger space can support long runs, passing tracks, sidings, yards, and multiple railroad scenes.

Straight sections and curves establish the route, while turnouts and switches let trains leave the main line for industries, stations, storage tracks, and other destinations. Even a relatively simple track plan can offer plenty of operation when every inch of space goes further.

Before laying Z Scale track, think beyond what will physically fit. Curve radius, turnout placement, siding length, and the locomotives and rolling stock you plan to operate can all influence how well the finished railroad runs.

A tighter plan may be perfect for a small layout, while broader curves and longer stretches of track can give longer trains more room to shine. Leaving space for stations, industries, scenery, and access to the track can also make the finished layout easier to enjoy and maintain.

Z Scale track uses a 6.5mm gauge, but gauge is only part of the equation when choosing track. Rail code describes the height of the rail in thousandths of an inch, and Z Scale track can be found in Code 40, Code 55, and Code 60.

Code 40 Z Scale Track

Code 40 rail is .040 inches high. Its lower rail profile can provide a finer-scale appearance, but compatibility with existing track and equipment should be checked before adding it to a layout.

Code 55 Z Scale Track

Code 55 rail is .055 inches high. When shopping Code 55 Z Scale track, check the manufacturer and track system along with the rail code, especially when connecting it to track you already own.

Code 60 Z Scale Track

Code 60 rail is .060 inches high. Like other rail codes, it may require attention when transitioning to a different rail height or combining track from different systems.

Two pieces of track can both be Z Scale and use the same 6.5mm gauge without being directly interchangeable. Rail code, rail profile, connectors, roadbed, curve geometry, and turnout design can vary. When expanding an existing railroad, identify the track system you already use and compare its specifications with the track you're considering.

Older Z Scale layouts can depend on track sections, switches, or other pieces that are difficult to find new. Trainz buys pre-owned collections, which can bring used, vintage, discontinued, new old stock, and assorted lots of Z Scale track back onto the market.

That can be especially useful when you're expanding an established railroad rather than replacing an entire track system. For pre-owned track, check the listing for rail condition, connectors, ties, switch operation, missing components, and signs of previous installation.

If you have Z Scale track or a larger model train collection you're ready to sell, Trainz buys qualifying collections that can include track, switches, trains, structures, accessories, parts, and other model railroad equipment. Learn how to get started with Sell My Trains.

What gauge is Z Scale track?

Z Scale track uses a 6.5mm gauge, meaning the distance between the rails is 6.5mm. Z Scale model trains are typically built to a 1:220 scale ratio.

What rail codes are available for Z Scale track?

Z Scale track can be found in Code 40, Code 55, and Code 60. The code represents rail height in thousandths of an inch: Code 40 is .040 inches high, Code 55 is .055 inches, and Code 60 is .060 inches high.

What is the difference between Z Scale gauge and rail code?

Gauge is the 6.5mm distance between the rails. Rail code describes the height of the rail itself. Code 40, Code 55, and Code 60 can therefore all be Z Scale track while having different rail heights.

Is Code 40, Code 55, and Code 60 Z Scale track interchangeable?

Not automatically. Although they use the same 6.5mm gauge, their rail heights differ. Track system, rail profile, connectors, roadbed, and geometry can also vary, so compatibility should be checked before combining track.

What types of Z Scale track are available?

Z Scale track can include straight sections, curves, turnouts or switches, crossings, and other specialized track pieces for building main lines, sidings, yards, and more.

Is all Z Scale track compatible?

No. Z Scale track can share the same 6.5mm gauge while differing in rail code, rail profile, connectors, roadbed, and track geometry. Check the manufacturer and track system before combining different types.

How much space do I need for a Z Scale layout?

Z Scale can fit into very compact spaces, but the room you need depends on curve radius, train length, track plan, scenery, and the type of operation you want.

Can I find used or discontinued Z Scale track?

Yes. Trainz's changing pre-owned inventory can include used, vintage, discontinued, new old stock, and assorted lots of Z Scale track.
