Platform Canopy Trusses
Posted by MackeyBloom on Friday, May 12, 2017 8:44 PM

I am building a model of the railroad station at Wallangarra, NSW, Australia.  It features two different platform canopies: one is arched (NSW side) and the other is essentially flat (QLD) side.  I am looking for source of trusses to support both canopy styles.  I've reviewed catalogs from most or all sources of building-parts with no luck.  Any ideas where else to look?

Sure would help to see what kind You are referring to.

Also did You look at Plastruct offerrings? Here's a PDF link to their catalog if You need it:

Also Central Valley Model Works make Laced Boxgirder kits in different sizes if You need those:

Good Luck! Big Smile

EDIT: If this is the station.....You will more than likely have to scratch/bash all the trusses and the ornate gussets.....judging from the blueprints which You will find about mid-way in the link. I do a lot of scratch/bash buildings and bridges and have not found any ready made parts like are needed:

The OP could check out Grandt Line stuff.  They have a lot of architectual stuff.

Might be able to find something close for all of the decorative work on those canopyies.

I'd guess that the straight trusses could be built without too much difficulty using Evergreen styrene angles.  
The arched-roof trusses would probably be easier done using plain dimensional strip styrene, for at least the curved top chord.  The rest of the components could be suitably-sized strip material or, if the trusses will be subject to close scrutiny, structural styrene shapes, as appropriate.

I'd do a full-size scale drawing of each style of truss, then pin the drawings to a sheet of 1/4" balsa.  If the drawings were covered with waxed paper, the trusses could be then built right on the protected drawing, using pins to hold the components in place. With styrene construction, you need only touch a brush loaded with solvent-type cement to each area where there's a joint, and it doesn't take too long before the joints are solid.  
Once one truss is complete, remove only enough of the pins to allow the truss to be lifted free, then repeat the process until you've made all that are needed.

This stockyard, and several similar, but smaller ones, was built in the manner described, then the various sides were assembled on-site...

Likewise, the roof trusses of this coal dealer's shed...

....were put together using the same method...

They're very basic, so use only plain strip material and are visible only when the big hand lifts the roof and flips it over for the camera or an interested visitor.
