GME: GNOME MINIATURE ENGINEERING: O and G scale plate girder bridges

Bridges for G scale, O scale, and larger scale model railways

__________________________________________________________________________________

GARDEN RAILWAY BRIDGES: Gnome Miniature Engineering structures are hand built from laser cut, brake formed parts, and assembled by traditional solid riveting. They capture the proportions of full size bridges, but are multi-scale working structures for small railways rather than exact scale models. The design and construction allow us to build custom bridges to your own requirements at a reasonable cost where standard parts can be used.

Our standard bridges are built for year round operation outdoors, so corrosion resistant materials are used throughout. They are ready to use, painted or unpainted, except for the construction of the bridge piers and installation of the track by the customer. They can be used with track from 16.5mm gauge for 0n30 to 63.5mm for Gauge 3.

G SCALE BRIDGES: plate girder bridges and underslung trusses for G and larger scales.

O SCALE BRIDGES: plate girders, through and underslung trusses, and operating bascules.

SPECIAL STRUCTURES We are now working on specials to be used for displaying model locomotives up to 1:8 scale, 7 1/4 inch (184 mm) gauge, and will be building the heavier versions in mild steel - more information coming soon.

EDUCATIONAL MODEL STRUCTURES: All truss bridges are available as educational models to demonstrate the principles and properties of pin jointed structures. These will normally be supplied without paint finish or decks. Material and section data will be made available.

The catalogue number (TR32 etc) indicates the type and length of the bridge deck in inches. For prices, availability, installation drawings and enquiries about custom designs,

Standard plate girder lengths (intermediate lengths available as specials):
Model no. PL12     12 inches (305mm)
                   PL24     24 inches (610mm)
                   PL36     36 inches (914mm).
Widths:
                                 4 inches (102 mm)

                                 2.0 inches (51 mm).

You can order any combination of length and width, and we'll be happy to discuss specials. A timber deck with attachment hardware, for standard or narrow gauge tracks, is included in the price.The current maximum length is 36 inches (914 mm) for a single span without intermediate supports.
