Williams Diesel Locomotives

Shop Williams diesel locomotives and engines for traditional O Gauge 3-rail railroads, with models ranging from streamlined cab units to switchers and road diesels. Williams produced many of these locomotives in multiple railroad paint schemes, giving shoppers plenty of options for matching a favorite road name, building a consist, or adding another diesel to an existing train.

Trainz inventory can bring together Williams Electric Trains and Williams by Bachmann diesel locomotives from different generations, including individual engines, multi-unit sets, and pre-owned models that may no longer be readily available new.

Several classic American diesel designs have become especially familiar within the Williams lineup, giving shoppers plenty to look for beyond a particular railroad name.

Williams F3 & F7 Diesels

F units are an important part of the Williams diesel lineup. F3 and F7 locomotives have appeared in different road names and configurations, making them popular choices for both passenger and freight trains. Because the F3 and F7 are different prototypes, the exact designation should be matched to the individual model.

Williams E7, E8 & E9 Diesels

Williams E units bring the streamlined look of classic passenger power to O Gauge. E7, E8, and E9 locomotives can appear in different railroad schemes and configurations, making them useful choices when matching or building passenger consists.

Alco FA, Baldwin Sharknose & Road Diesels

Williams also produced distinctive Alco FA and Baldwin Sharknose locomotives along with switchers and other road diesels. The mix gives shoppers a wider range of locomotive styles and eras to choose from as inventory becomes available.

Williams diesels are frequently encountered in multi-unit configurations. Depending on the release, shoppers may find powered A units, unpowered or “dummy” companion units, B units, and AA or ABA locomotive sets.

The distinction is important when buying older Williams equipment. Two matching units may look nearly identical even though only one is powered, while an unpowered B or companion unit may have been designed specifically to complete a larger consist.

Check the individual Trainz listing to see exactly which units are included and whether each is powered or non-powered.

Williams is strongly associated with straightforward O Gauge 3-rail operation, and many Williams diesel locomotives were designed with traditional transformer-controlled layouts in mind. That makes Williams a natural choice for operators looking for diesel power for a conventional O Gauge railroad.

Sound & Operating Features

Features vary by model and production era. Some Williams diesel engines include horn and bell sounds such as True Blast or True Blast II, while other releases may have different electronics or more basic conventional operation. Sound and control features should be verified for the specific locomotive.

Curves & Layout Requirements

Minimum curve requirements also vary. Some Williams diesels can negotiate O-27 curves, while larger locomotives may require broader curves. Checking the minimum curve and operating requirements before buying helps ensure the locomotive is a good fit for your railroad.

The Williams name spans more than one generation of O Gauge trains. Older locomotives may carry Williams or Williams Electric Trains branding, while Bachmann acquired Williams Electric Trains in 2007 and continued the line as Williams by Bachmann.

Trainz regularly acquires pre-owned collections, so older Williams diesel locomotives can return to inventory alongside later Williams by Bachmann releases. That can include F units, E units, Alco FAs, Sharknose locomotives, road diesels, powered and dummy units, and complete locomotive sets.

If you're searching for a particular Williams diesel engine or locomotive, details such as the model number, road name, powered configuration, sound system, packaging, and production era can help distinguish similar releases.

Trainz buys qualifying model train collections that can include Williams and Williams by Bachmann locomotives, rolling stock, train sets, and other O Gauge equipment.

Are Williams diesel locomotives O Gauge?

Williams is best known for O Gauge trains, and Williams by Bachmann is a 3-rail O Gauge product line. Specifications should still be checked when identifying individual older Williams releases.

Will Williams locomotives run on Lionel track?

Williams O Gauge 3-rail locomotives can often operate on compatible Lionel 3-rail track. Minimum curve requirements and the locomotive's power and control requirements should be checked for the individual model.

What is the difference between Williams and Williams by Bachmann?

Williams Electric Trains existed before Bachmann acquired the company in 2007. Later products have been marketed under the Williams by Bachmann name, while older pre-owned equipment may simply carry Williams or Williams Electric Trains branding.

What is a Williams dummy locomotive?

A dummy or non-powered unit is a locomotive-shaped unit without its own drive motors. It runs as part of a consist with a powered locomotive and was commonly used by Williams in multi-unit diesel arrangements.

Do Williams diesel locomotives have sound?

Some do. Williams produced diesel engines with different sound systems over the years, including models equipped with True Blast and True Blast II horn and bell sounds. Not every Williams diesel has sound, so check the individual model's features.

Will Williams diesel locomotives run on O-27 curves?

Some Williams diesels can operate on O-27 curves, but minimum curve requirements vary by locomotive. Larger models may require broader curves, so check the specifications before purchasing for an O-27 layout.

Can I still buy older Williams diesel locomotives?

Yes. Trainz's changing pre-owned inventory can include older Williams and Williams Electric Trains diesels, discontinued individual releases, powered and dummy units, locomotive sets, and harder-to-find road names as collections become available.
