DURANGO THROUGH PLATE GIRDER BRIDGE KIT
Modeler provides their own track materials.
To purchase: Send an email to be added to the list.
A group of kits is being readied for earlier inquiries. Production on more kits will start
this week for later inquiries and new requests.
One section of the Animas River bridges in Durango CO is a through plate girder bridge. It is a main-line
size span about 80' long that carries the tracks right into the 452a through truss. The Durango and
Silverton runs their trains daily over this bridge.
I wanted to offer a simple to build kit that is fully detailed and is useful for many modelers. This typical
through girder will hold standard-gauge equipment as well as the large narrow gauge locos that use it
regularly. It will assemble with ACC (super glue) adhesive.
The 3D files were made into printed master parts. I made the RTV molds and cast parts for the model.
The model has styrene I-beams for stringers and 3D printed clevises for the brass brace rods.
|Durango Through Plate
A through plate girder bridge is such common
prototype! It is a valuable bridge for 1:48 modelers, from
the D&RGW prototype followers to any On3, On30 or O
standard modeler wanting a scale, prototypical bridge.
WHEN?: I have some sets of parts being readied for
earlier previous inquiries. Then I have to renew the RTV
molds and make a bunch more parts for later inquiries and new
OK, SO REALLY WHEN?: Mailing boxes are coming this week. I
have been contacting folks per the date of initial inquiry (some
back to 2015!). When I am out of this batch I will contact all
other more recent inquiries. I am also getting a new master floor
beam 3D printed and to make the new molds.
ARE YOU INTERESTED?: Send me an email and I will save it to
my Durango Girder Bridge folder. No deposits taken or needed!
Thanks for your interest in this new bridge model project.

This rendering of the CAD files was
created for the master parts.
This end view shows how the bridge
looks with detailed track.
The side view demonstrates the correct proportions of this typical
girder bridge. The model is 15-5/8" long and 4-3/8" wide.
Looking down into the bridge reveals the
sway brace rods, rod clevises and the detail
of the floor beam connections. There are
numerous layers of plates piled up on the
prototype. They are all here in 1:48.
This photo is of my completed model with 3' gauge track I made. It went together nicely as shown.
The floor beams are one-piece castings. They glue on to indexed location on the girders. The
girders are two parts with the top and bottom plates running across the joint for strength. The
stringers are Evergreen Styrene I-beams, and there are brass rods for the lower sway rods with 3D
printed clevises. It makes for an accurate model of a through girder bridge. It has that look of being
correct. I made sure the rivets are in logical locations on both sides of connections.
I like rivets, especially when they are in
the correct locations.
|Here is the bridge in black undercoat before I went
crazy with the weathering on silver overcoat..
Above are the real parts on the casting bench- two mold halves, a floor beam still
in the mold and a finished floor beam with the big sprue chunks removed. The floor
beam castings will come with the sprues on the ends to protect the gusset plates.
These little fellas are 3D printed clevises for the brace
rods on the bottom. They are included in the kit.
The unpainted completed bridge shows the parts- black
are the castings, white are the styrene I-beams and brass
are the brace rods. The small clevises are visible too.
The bottom of the bridge has nice detail including the
