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

Decks

Prices include timber decks consisting of transverse timbers with longitudinal guard timbers. Assembly is with nails, and screwed cleats secure the deck to the structure.


0 and S scale decks for indoor use are precision milled basswood sections from Mount Albert Scale Lumber, either stained to resemble fresh creosote or with a simulated weathered appearance.

This illustrations show four different red cedar outdoor decks after weathering for up to six years.
(above) L-R: (1) pictured after 6 years exposure, no stain, no preservative; (2) 6 years, stain with preservative; (3) 5 years, stain with preservative;  (4) 3 years, stain with preservative. They are exposed to sun, rain, snow, salt, cats, deer, raccoons, squirrels and birds. After 7 years exposure, the specimen on the left appealed so much to one customer that he asked for it to be installed on his TR42M. Happy to oblige! Properly drained, the cedar weathers well and keeps its strength.

The standard large scale decks are red cedar, stained or unstained. For Gauge '1' the transverse timbers are 5 inches (127 mm) and for 'G' they are 6.4 inches (162 mm) long, corresponding to roughly 13 feet (3,962 mm).
All decks can be supplied with short extensions to cover the gap between the bridge and the adjoining structure. Decks designed to your own requirements are also available.
