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

Custom bridges

A large proportion of our work is to special customer requirements, such as this 1:8 scale steel display bridge - a favourite project, using 7 1/4 inch gauge track parts from The Miniature Railway Supply Co.


































The most economical approach to a custom design is to base it on standard parts. Contact us to discuss your ideas and requirements. A request for something you don't see in the illustrations will sometimes lead to a new product that will be of general interest. The picture below shows the first of many 'specials'; this one for a large 0n30 railway, using mostly modified standard parts.

Masonry viaducts appearing to be curved are common, but there was rarely a horizontally curved steel bridge until the development of modern welded box girders. Most bridges that appear to be curved are a series of straight sections, and this is how we build a curved bridge. For a sharply curved bridge, the girders will be trapezoidal in plan, as in the example for an 0n30 railway shown here:
