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, assembled by traditional solid riveting.

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 more information, please contact us at

How they are made

For the standard structures, each part is laser cut from aluminium alloy sheet, cleaned, deburred, brake-pressed, joggled if required, and then riveted into the assembly using solid rivets. Here is a plate girder rib as cut and after forming:

Parts are often altered from standard to suit particular variants, and this is mostly done by hand.

Below is a sub-assembly of an all steel custom bridge that went to a client in Türkiye to display his 1:8 scale live steam locomotive (see bottom of the page):
