Buying O Tubular Track

Whether you're restoring a postwar railroad, replacing worn sections, or expanding a traditional O Gauge layout, O tubular track remains one of the most recognizable track systems in the hobby. Many collectors continue using tubular track because it matches the railroads they've owned for years while making it easy to add replacement sections and accessories.

Trainz regularly offers O tubular track for sale in brand-new, used, pre-owned, vintage, estate-fresh, and hard-to-find condition. Inventory may include complete track lots, straight sections, curves, switches, crossings, lockons, terminal track, rerailers, and other replacement components.

Choosing the Right Tubular Track Diameter

Not all O tubular track uses the same curve diameter. Traditional layouts commonly use O31 track, while larger railroads may use O42, O54, O72, or broader curves to accommodate longer locomotives and passenger equipment. Matching the diameter already installed on your layout helps ensure reliable operation and consistent track geometry.

If your railroad uses tighter O27 geometry, browse O27 tubular track products for compatible sections, switches, and accessories.

Building and Expanding with Tubular Track

One reason tubular track has remained popular for decades is its versatility. Railroads can begin as a simple loop before expanding with passing sidings, freight yards, industrial tracks, passenger stations, and operating accessories using readily available replacement sections and specialty track.

Planning future expansion before purchasing additional track can help maintain consistent curve sizes and simplify the addition of switches, crossovers, and operating accessories as your railroad grows.

What is the difference between O tubular track and O27 tubular track?

O27 tubular track uses tighter curves and a lower rail profile than traditional O Gauge tubular track. It is often chosen where space is limited, while larger O Gauge tubular track diameters provide smoother operation for larger equipment.

Does Trainz sell used O tubular track?

Yes. Trainz regularly offers used, pre-owned, vintage, estate-fresh, and hard-to-find tubular track whenever inventory is available.

Can I buy replacement tubular track sections?

Yes. Depending on inventory, you may find replacement straight sections, curves, switches, crossings, lockons, terminal track, insulated pins, and other tubular track components.

What curve size should I choose?

The best curve diameter depends on the locomotives and rolling stock you plan to operate. Larger passenger cars and scale locomotives generally perform better on broader curves such as O54 or O72, while smaller traditional equipment often runs well on O31 layouts.

Is vintage tubular track still worth buying?

Yes. Many collectors and operators continue using vintage tubular track to restore classic layouts, expand existing railroads, or maintain original postwar train sets.
