Altnaslanach Bridge

Completed in 1897 the bridge (viaduct) lies on the line between Aviemore and Inverness and crosses the Altnaslanach burn near Moy. Built with green oak it could be used on the marshy ground and still survives as the last mainline timber crossing in the UK albeit reinforced with contract since 2003.

The kit comes in 2 parts:

• A Single “SPAN” Kit for the bridge (3xA4 4mm Ply Sheets (1 x 0.8 mm sheet))
• A kit for the “ENDS” of the bridge (1xA4 4mm Ply Sheets (1 x 0.8 mm sheet))

A SPAN plus ENDS will build a single span bridge. 

To build the Altnaslanach Bridge requires 2 SPAN kits and 1 ENDS kit.

Longer viaducts can be constructed by adding SPAN kits.

This bespoke model has been designed in 1/76 scale to capture the detail of this historic A listed structure.

The building requires glue. Choose a glue that allows at least a minute before setting to allow adjustments to be made during the build. Always test the build before using glue.

For finishing, we recommend first priming the surface, then painting with any acrylic or model paint of your choice. The material is etched, so any engraved detail such as brickwork or roof tiles will be visible after painting.

Important information about railway scaling: 

All kits are designed in OO Gauge on 3mm plywood, so there are a few considerations to be made when scaling the digital files to other Gauges. The instructions provided will be the OO version as the build order is the same at different scales.

O Gauge Orders: When scaling to O gauge, there are manual modifications that may need to be made when assembling the kit. This is due to the thickness of the plywood when scaling the kit from the OO gauge material of 3mm to the O gauge 5.25mm material that would be needed. As this thickness of ply does not exist, we undersize the material to the closest thickness we have of 4mm plywood and recommend dry fitting the build first so that any joints that need to be sanded for a flush finish can be noted.

N Gauge Orders: Scaling to N gauge works well and has no extra modifications needed due to material thickness. Some parts will be very fine, so take care when removing them from the frame. If some window pieces are particularly fine, they can be reinforced by soaking them in glue before assembly.

TT Gauge Orders: Scaling to TT requires slightly more modifications of the designs before cutting, so please contact us if you’re interested in a kit, and we can provide you a quote at info@popupdesigns.co.uk.
