I am trying to create a 3D CAD drawing of the old Dushore Trestle.
 
I have collected many photos, but no drawings (best one so far attached).
 
Any help welcome, and if and when I finish this project it will be free to anyone who wants it.
 
Thanks!

I have finished my first draft of the Dushore trestle. I downloaded XYZ data and compared it to old topo maps to obtain the terrain around the trestle in order to place the base supports, work around the Little Loyalsock Creek and Mill Road. A rendered png view of the 3D trestle model is attached.
 
Things that I know are wrong, the base supports, looks like from the photos they were concrete, also I know I over simplified the cross supports, just can see through the pictures into the interior of the trestle. Also the abutments at the creek are pure guesses.
 
Wish I could walk over and check out to see if the bases near the creek are still in place, just cant since I injured my back putting me into a wheelchair.
 
The overall length of the trestle is roughly 580 ft bank to bank. That would be some 80 in HO scale. The trestle was 50 ft (some 7 in HO scale) at its deepest. Going to work on a more manageable shortened version for my layout next.
 
Again, anyone who sees an error please let me know, I just want to get it right!

jgh3, that's a nice rendering!
 
Just a couple of random thoughts--
 
1.  In your photo, some of those footings look like they are made of concrete blocks, or perhaps even dressed stone, rather than poured concrete.  Is this a possibility?
 
2.  Do any traces of the right of way remain?  If you know the precise location of this trestle, you might see a fair amount of detail on Google Maps  ( http://maps.google.com ).  You may even be able to get a rather accurate frame of reference for the scale, the precise locations of the footings, etc.  Even if all you can see is straight down, it would at least tell you whether the footings still exist-- and if there are nearby streets, the "Street View" from those locations (which can be panned up and down as well as side to side) may give you further information.
 
 
I wish you well,
 
Norm

Norm,
 
Thank you!
 
Although I used Google Maps and Google Earth (has older satellite and topo maps that can be viewed) I did not think to use the Street View. Unfortunately no joy. They erased most traces except on the North Bank (see photo) where the foundations can be seen.  
 
I know that they used dressed stone, and concrete, You are probably right in that they lay preformed concrete block on top of the dressed stone as I think can be seen in the blow-up of the wreck photo also attached. in next reply.
 
John

Norm,
 
The closeup of the foundations appear to be stone and concrete. Just no way the edge could be that uniform with stone.

Norm final photo, a 2005 Sat photo was taken in the winter it appears, great no foliage.
 
The old Station is still there, building to the far left. The track passed square to the large building in the photo, but as you can see most remnants have been removed.
 
Oh well it makes it interesting. Use to do reverse engineering for the USMC before I retired from the USN as a Naval Architect.
