Model Structures for Model Railroads

Curved Trestle Deck

This is something new I designed and assembled for my layout. The design is a prototype now so will undergo modification as it matures. The bottom chords have been laminated from thin strips using a jig designed for an 054 radius so the entire deck is one piece and very stable. For this prototype the deck ties were glued by sight only. An alignment jig will need to be designed for future product. Since glue up jigs would have to be built for all the different track radii available Model Structures encourages anyone interested in purchasing curved decking to contact us. Right now if you are in need of an 054 or O72 radius deck we are good to go. Just contact us for a quote.

O ScaleTrestle Deck Bulkheads

These bulkheads are designed to be used at the ends of the trestle decks or any of the bridges offered. The bulkheads start with a cross plank of 3 1/2" at the top sill and steps out to approx. 7 3/4" at the bottom sill. The total height of the nine cross planks is about 3 1/4". There are five posts 5 1/8" in height.

Please note the bulkheads come as a set of two.

O Scale Double Stack Trestle Bent

The double stack bent has been redesigned! There are times when a double stack trestle bent is required for spans that can not accommodate normally spaced bents. The double stack can be built on either O scale or HO scale and in any height required. Shown below is a HO scale version. Please let us know if you are interested in purchasing any.

O Scale Trestle Bents

The Trestle Bent design has changed to incorporate more sway braces. The bents are 3/4" thick and 4 3/4" wide at the bottom and 3 1/2" at the top. The bents are now available in four standard heights of 4.5", 5.5", 6.5", and 7.5" (shown above). The bents are sold separately. Custom heights are available upon request.

O Scale Bridges and Trestle Decking for Model Railroading

All bridge designs have been modified to make them a lot more sturdy. Inserts have been added to the top and bottom chords to give more glue surface. The dadoes in the bottom chords have been deepened to add more glue surface. The tie bars have been made smaller (more prototypical) and therefore more added to increase stability. All product sold is assembled and finished with a coat of oil. Please remember custom lengths are available for all product. All product shown below is designed for O scale railroading. On30 model railroaders who design in 1:48 scale can also use this product on their layouts.
