I needed to rebuild some off my track layout on my Z-modules to
accommodate some longer and heavier train setups. In this
reconfiguration I saw that I could build a fairly large Wooden Trestle
Bridge on my side track. So here is the story off the building off
this Trestle. The total length of the bridge is about 500mm(19,7in) and the
max. height is about 90mm(3.5in). The height of the deck bridge in the
middle is only about 23mm.(0.9in)
I like
to work with real wood sins this give a real natural look and wooden
grain. I used a variety off Northeastern Wood products that I first
died
with Light Brown "Beis" (Paint).
Here I
have cut down the sidings of the module to ad more hight to the trestle.
I cut up peaces off electronic print card
for homemaking. This I filed down the middle off the copper to insulate
them so I could use it as Track ties.
Then I cut out some of the ties on a Peco
flexi track section and soldered the “new” ties in place before taking
all the original ties away.
I cut up a lot off new wooden ties and
glued them on to a new base for the bridge deck.
The total length off the bridge is about 50cm.
Here you can se the end connection off the
bride to the rest off the layout. I’m making it so that I can later take
it off and do future repairs and the bridge, and It makes it easier to
build the rest off the landscape around the bridge.
This is
the beginning of building the deck bridge that is going over the “Needle
Eye” river.
I used a small drill tap to make holes for
all the “nails” that I was gone apply to the bridge. This turned out to
be quit a time consuming job, it was a lot off ties connections to make.
Must have been at least a 1000 of them. But I think that the end results
will be good with a lot off details. For “nails” a used the wire from
some resistors that I filed down after cutting them off.
For the “tension” rods I also used the wire
from some resistors
For the trusses I made a “jig” in Corel
Draw and printed it out on paper.
Used
double sided tape to hold the timber in place while working. The
trestles are made the “correct” way that it would be built in real life.
(I think?) The trestles are built in a typical “Rio Grande Southern
Style” With some small customizations by me.
This is the first test installation to se
where the trusses could be placed before gluing the on to the bridge
deck.
After the trusses had dried I added the
brazes and stiffener to between the them and the bridge is ending its
construction completion. Now I have to detail it and whether it some
more before it final completion.
I also have to make the foundations
for the trusses before I continue with the rest of the riverbed and so
on.
As you can se here I had to cut out some
more of the sidings to so that I can ad some depth the the riverbed
under the deck bridge. I learn as go along with the building off all my
layouts.
