Custom and standard bridges for G scale, O scale, and garden railways

Gnome Miniature Engineering is located beside the Grand River in Ontario, Canada, an area we acknowledge to be the traditional lands of the Six Nations of the Grand River.

GME MODEL RAILWAY BRIDGES: Our structures are multi-scale working structures for small railways rather than scale models. They are hand built from laser cut, brake formed parts, and assembled by traditional solid riveting. Structures designed to your own requirements can be built at a reasonable cost when standard parts are used.

Standard bridges are built from corrosion resistant materials for year round operation on garden railways. They are ready to use, painted or unpainted, except for the installation of the track. They have been used with track from 16.5mm gauge for 0n30 to 63.5mm for Gauge 3.

GARDEN RAILWAY BRIDGES: plate girder bridges and underslung trusses for G and larger scales.

O and S SCALE BRIDGES: plate girders, through and underslung trusses, working bascule bridges.

EDUCATIONAL MODEL TRUSSES: The truss bridges are available as educational models to demonstrate the principles and properties of trusses. These will normally be supplied without paint finish or decks. Material and section data are available.

The model number (TR32 etc) indicates the type and length of the bridge deck in inches. For prices, availability, installation drawings and enquiries about custom designs, please contact us at

GME news

The latest special project is a 100" (2.5 m) long bridge with an unusual offset deck to allow it to be attached to a wall to display the owner's G scale rolling stock. It was supplied with hand laid track using Micro Engineering components, painted and weathered. The handrail stanchions are a new product that will be available separately.
Two 6 ft long (1,830 mm) viaduct assemblies for 1:20.3 scale, based on the Glen Wyllin viaduct on the Isle of Man,  are now with their new owners in England and Tasmania. These were built as specials based on the PL24 plate girder, with plated decks, refuges and handrails. A further small batch might be built if there is sufficient interest. 

If you are interested in curved plate girder bridges, please note that, just like many full size riveted bridges, GME bridges consist of short straight sections with timber decks supporting the curved track.

Please continue to visit Credit Valley Railway Company for 0 and S scale and Bigboyztrainz for G scale structures. All other enquiries as usual to
