NEW for 2025!

This is our new viaduct system depicting a modern concrete viaduct. Suitable for single and double tracks in HO gauge.

3D printed in attractive matt grey it's ready to place on your layout or paint as required.

Please note these are manufactured in our UK factory and delivery may take up to 2 weeks.

Comes in sections and can be made any length and any height, just buy as many parts as you need! Each part has locating dowels and can easily be glued together.

Note cannot be used for inclines or curves.

To calculate the required parts:

First measure the overall length of the viaduct required. Now select the track bed parts for either single or dual track widths. These are available in two lengths either 2 in (50mm) long or 4 in (100mm) long. These simply glue together to make up the required length

Now measure the required height of the viaduct from the baseboard to the track bed and deduct 4 in (99mm) from this height. This gives you the height of the support posts and these parts are built up from 3/16 in (20mm), 2 in (50mm) or 4 in (100mm) tall sections. These can be stacked to create a taller viaduct. The support posts are the same for both the single and double track viaducts.

Now count how many support posts you require. You can fit a support post every 2 in (50mm) although you would probably want far fewer than this.

Finally you will require one support post connector for every post. This connects the support post to the track bed and is the same for single and double tracks.

The double track viaduct is 6-11/16 in (170mm) wide with track centers at 2-9/16 (65mm)

The single track viaduct is 3 in (76mm) wide.
