64’ Through Plate Girder Bridge in N Scale
Supplied Kit Components:
• 2 sheets of laser cut and engraved stabilized Resin Impregnated Board (RIB) for crisp, high resolution detail
• 2 sheets of laser cut mat board • Detailed instructions
Suggested Tools and Supplies:
• X-Acto type knife with fresh blades (#11 style is best) • Tweezers • Fine sandpaper (400+ Grit) • Masking tape or clear adhesive tape • Probond, Elmers white glue or Scotch Quick-Dry Adhesive (I like the Scotch adhesive as it dries with
little residue and has a great fine applicator tip) • CA glue for immediate bond of small hard to place parts • Acrylic or enamel paint
We hope you enjoy making this kit as much as we did providing it to you. If you have any questions, please contact us at [email protected].
The following instructions and photos will provide the basics for assembling this detailed kit. We have tried to make the steps as straight forward as possible, but please note that you might want to change the order of assembly to suite your own technique and modifications that you might make along the way. As usual it is best to familiarize yourself with all the parts and instructions before you start on this craftsman level kit.

This kit comes with 2 sheets of laser cut 0.018” thick RIB,
and 2 sheets of .060 mat board.
You will need to supply your own rails.
1
Start by cutting out the pieces of the kit with a new X-
Acto blade.
Sandwich the mat board beam and frame panel between
the two matching RIB panels. Note the alignment of the
slots in the end of the cross beams.
2
I like to run a bead of glue along the glue faces and
then after sticking the parts together, clean out the
groove of any exposed glue to alow the gussets to be
installed in a later step.
3
Place a heavy weight over the assembly and let the
glue set up to assure a straight base for your bridge.

Sandwich the 5 layers together for each girder as
shown in these 4 pictures.
Once you assemble the girders, sand the top, bottom and
ends to square up any mis-alignment that may have
occurred during the gluing operation. I also suggest filling
any larger glue lines, etc before sanding and painting.
The girder formers should fit nicely into the end slots
of the beam and frame assembly.
5 Cut the gussets from the sprue and glue them
together.
I find stabbing the tiny parts with a #11 X-Acto blade and
then dipping the part in glue is a easy way to layer these
tiny little parts!
6
This is a good time to paint all the assemblies.

Glue one of the girders to the bottom frame assembly. It
should fit into the slots in the cross frame ends. Glue the
other girder in place and square up the girders.
7
The 10 gussets are glued in place equally spaced on each
cross frame. The 4 smaller end gussets fit up against the
radiused end flanges.
8
Each gusset sits in the slot of each cross frame.
Glue the diagonal bracing panel to the bottom of the
bridge assembly
9
Paint the rail tie assembly a dirty brown and then a dark
grey/black wash to simulate the creosoted ties. Run a
bead of glue down the length of the tie joiners and glue in
place over the center beams of the bridge.
10
Glue the safety beams flush to the top, outside edge
of the ties.

Next, glue the rails to the center of the tie joiners. For a
proper width, use a piece of track for the proper gauge,
as shown.
11
Alternately you can use a piece of track, with the ties
torn out, along the length of the bridge to help with
laying the bridge into your layout and keeping the
rails the proper gauge.
12
Glue the 4 feet (two pieces doubled up each foot) to
the ends of the bridge.
A little aging with alcohol india ink wash and weathering
powders.
13
A little graffiti and some rust makes ‘er look real!
