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

Gnome Miniature Engineering is located beside the Grand River in Ontario, Canada, acknowledged 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 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 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. These will normally be supplied unpainted and without 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

0 and S scale bascule and truss bridges

The BA24 0 scale bascule bridge (sometimes called a drawbridge) is an operating trunnion type with an opening of just over 18 inches (457 mm).

This model may be discontinued when the present stock of parts is exhausted. Until then, the basic structures (pedestal/trunnion frame/ lifting section) will be available for completion and detailing by the customer, at a lower cost than the complete bridge, of course.

The bascules can be used as road bridges for Gauge 1 as well as 0 scale. Let us know if you would like this version, and it will be supplied with a close timbered deck.

The basic range of 0 scale through truss bridges for 1:48 and 7 mm:ft. is shown below. Some customers are finding that these bridges serve well on S scale railways.

0 scale truss bridge dimensions:
Span:                              TR24    24 inches (610mm)
                                       TR32    32 inches (813mm)
                                       TR42    42 inches (1067mm).
All 0 scale through trusses are now available in double track versions
Inside width:                 3.75 / 7.25 inches (95 /184mm)
Outside width:              4.45 / 8.03 inches (113 / 204 mm)
Inside height from deck:        5.0 inches (127 mm).
