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

Gnome Miniature Engineering is located in Ontario, Canada, in a place that we acknowledge to be the traditional land of the Six Nations of the Grand River.

GME MODEL RAILWAY BRIDGES 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 are available 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 girders and underslung trusses for G and larger scales.

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

EDUCATIONAL MODEL TRUSSES: The truss bridges are available as educational models to demonstrate the principles and properties of trusses.

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

Frank Grantham 1933 - 2018

We are saddened to record the death of Frank Grantham, a mechanical designer par excellence, who was one of the original partners in GME. He was responsible for the detail design of the basic structures of a series of bridges that continue to be shipped around the world, from Canada to Tasmania. Frank had served a craft apprenticeship in the UK, and we knew each other first as colleagues at a Canadian company building naval aircraft handling equipment. Following his retirement he helped set up Gnome Miniature Engineering, combining professions and hobbies. Always a fine designer, a meticulous model maker, a good friend and a most congenial colleague, he will be missed.
