There's More to an MTH Railroad Than the Trains

MTH accessories fill in what happens around the track. Signals and crossing gates add railroad action, figures and vehicles populate the scene, lamp posts and beacons add light and detail, and signs, billboards, containers, freight loads, scenery, and accent pieces help turn open layout space into something recognizable.

Whether you're detailing a town, working on a freight area, or adding the last few pieces around an established 3-rail railroad, this is where to shop the smaller MTH accessories that bring those scenes together.

MTH Operating Accessories & Layout Details

MTH Operating Accessories Add Another Kind of Action

MTH operating accessories can make the layout part of the operating session. Loaders, signals, crossing accessories, animated scenes, and other action pieces may incorporate movement, lights, sound, or interaction depending on the release.

What to Check When Buying Pre-Owned MTH Accessories

Shopping pre-owned? Check the specific accessory's operating condition, power or control requirements, and what's included. With an older operating piece, a missing load, figure, controller, wire, or other component can matter.

MTH Signals, Figures, Vehicles, Loads & the Details Between

Details for the Railroad and Surrounding Scenes

MTH signals, railroad crossing gates, lamp posts, lights, figures, vehicles, road signs, billboards, freight car loads, containers, and scenery all solve different layout problems. Some belong right beside the rails; others help build out streets, industries, yards, and the areas beyond the right-of-way.

MTH Buildings

Assembled MTH structures have their own selection. If the scene needs a station, house, storefront, factory, or another finished structure, browse MTH O Scale Buildings.

Hunting for an Older MTH Accessory?

A discontinued MTH signal, operating accessory, vehicle, loader, figure set, or other layout piece can be surprisingly difficult to replace once it's gone. Trainz buys model train collections, so pre-owned and hard-to-find MTH accessories can return to Trainz.com as inventory changes. Check individual listings for condition, completeness, and operating information where applicable.
