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

2017 was a year of special projects! We'll take on fewer of the larger ones this year in view of increasing material costs and the length of time it takes to design and build them. As always, enquiries about specials based on standard bridges and parts are welcomed. 

The latest was a three track, five feet long bascule using some existing parts, but largely a new design - it won't be repeated!

Earlier in the year we built a 100" (2.5 m) long display 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.
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

Please note that our curved plate girder bridges, just like many full size riveted 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 Gauge 1 and G scale structures. All other enquiries as usual to
