Atlas HO Scale Track

Atlas HO Scale track covers much more than the basic straights and curves needed to get a train running. Code 83 and Code 100 systems give HO modelers access to flex track, sectional pieces, turnouts, switches, crossings, rerailers, joiners, and other components for building everything from a first main line to a busy yard.

If you're adding to an existing railroad, start by identifying the rail code and track already installed. Building from scratch gives you more freedom to choose a system based on appearance, geometry, available space, and how much of the railroad you want to shape with Super-Flex rather than predetermined track sections.

Trainz inventory can also include used and pre-owned Atlas HO track alongside newer pieces, making this page useful for both new construction and the hunt for a missing section needed to keep an older layout growing.

The number refers to rail height. Atlas HO Code 83 uses .083-inch-high nickel-silver rail with finer brown ties, while Code 100 uses taller .100-inch nickel-silver rail with black ties. Code 83 offers the finer, more scale-oriented profile, while Code 100 remains Atlas's long-established HO track system.

Both systems extend beyond basic sectional track. Depending on the line and component, shoppers can find Super-Flex Track, straights, curves, crossings, turnouts, switches, rerailers, terminal sections, joiners, and other pieces for assembling a complete railroad.

Already have both rail heights on the layout? Atlas offers transition joiners designed to connect Code 83 and Code 100 rail, so using one does not necessarily lock the entire railroad into that same rail height.

Sectional track works well where predictable dimensions matter. Fixed straights and curves can simplify track planning, make replacement pieces easier to identify, and provide repeatable geometry in areas where you know exactly where the railroad needs to go.

Atlas Super-Flex Track is for the places where you don't want the railroad dictated by a fixed curve. It can be shaped for custom alignments and broader flowing curves, and Atlas offers HO Super-Flex in both Code 83 and Code 100. A Code 83 version with concrete ties is also available.

Turnouts and switches put that track to work by creating yards, passing sidings, industrial spurs, engine facilities, and branching routes. Atlas HO offerings have included Snap-Switches, Custom-Line turnouts, switch machines, wyes, and multiple turnout configurations. Check the rail code, direction, geometry, and operating method when matching one to an existing layout.

True-Track is Atlas's roadbed-equipped alternative to laying conventional HO track over separate roadbed. It combines Code 83 nickel-silver track with brown ties and removable molded roadbed, giving modelers a track system that can be assembled quickly while retaining a more finished roadbed appearance.

The track itself can be removed from the roadbed and used separately, which gives the system some flexibility if a temporary railroad eventually becomes something more permanent.

We've given this system its own Trainz page rather than making the broader Atlas HO track page compete for every True-Track search. If integrated roadbed track is what you need, shop Atlas HO True-Track for available straights, curves, switches, rerailers, sets, and other True-Track pieces.

Track doesn't always get purchased one fresh box at a time. An established railroad might need one matching turnout, a few curves of the correct radius, another section of flex track, or an older Atlas component that has become difficult to locate.

As previously owned model train collections arrive, Trainz inventory can include used Atlas HO track, switches, turnouts, track packs, individual sections, accessories, and larger track lots. That can be particularly useful when expanding an older railroad or looking for discontinued and hard-to-find Atlas HO pieces.

For used track, look beyond the quantity in the lot. Confirm the rail code and geometry, then check rail and tie condition, joiners, turnout operation, missing components, and exactly what is included before deciding whether it fits your layout.

What types of Atlas HO Scale track can I find?

Atlas HO track includes Code 83 and Code 100 systems with sectional track, Super-Flex Track, turnouts, switches, crossings, rerailers, joiners, and other layout components. Atlas also offers Code 83 True-Track with removable roadbed.

What is the difference between Atlas HO Code 83 and Code 100?

Code 83 uses .083-inch-high nickel-silver rail with finer brown ties. Code 100 uses taller .100-inch nickel-silver rail with black ties. Code 83 has a finer rail profile, while both systems provide components for building HO layouts.

Does Atlas make HO Scale flex track?

Yes. Atlas Super-Flex Track is available in both HO Code 83 and Code 100. Atlas also offers Code 83 Super-Flex with concrete ties.

Does Atlas make HO Scale turnouts and switches?

Yes. Atlas HO track systems include turnouts and switches in multiple configurations. Options vary by track family, so check the rail code, turnout geometry, direction, and operating method before buying.

What is Atlas HO True-Track?

Atlas HO True-Track combines Code 83 nickel-silver track with removable molded roadbed. Because Trainz has a dedicated page for the system, you can shop Atlas HO True-Track separately from the broader Atlas HO track selection.

Can Atlas HO Code 83 and Code 100 track be used together?

Yes. The rail heights are different, but Atlas offers transition joiners designed to connect Code 83 and Code 100 rail.

Can I buy used Atlas HO Scale track?

Yes, when available. Trainz inventory can include used and pre-owned Atlas HO track, switches, turnouts, flex track, individual sections, track accessories, and larger track lots.

What should I check when buying used Atlas HO track?

Check the rail code, track type, curve radius or turnout geometry when applicable, rail and tie condition, joiners, switch operation, item number, and exactly what is included in the listing or lot.
