Well guys after seeing Crandells pics of Kinsol Trestle I have decided to model it. Heres the ‘little’ beauty below.
The thing is 614’ long, 145’ above the river, on a curve and on the whole purdy darned BIG and impressive.
From these two measurements I can pretty much get the bent spacing, dimensions, river span & so on, but if anyone knows where I could get some more accurate info I would appreciate it.
I’ve done the google and yahoo searches but all that comes up is tourist info and such, the pic above is pretty much the best I can find after 1 week of searching this Wicked Weird Web [:(]
Any help or directional guidance much appreciated.
Thanks Red, I had worked out to 42, based on the size and dimensions I had calculated from the bridge span, this confirms my guesstimated calculations so far are not to wide of reality.
Well Crandell my friend, it looks like you are going to be my resident Kinsol expert !! sorry. I suppose its only fitting as it was your pictures that got me started on this project in the first place [:)].
In the crude diagram below can you confirm that :-
a) the tresstle runs straight for about 1/3 and then curves roughly through 60-70 degrees. This looks evident from the first pic in this thread, it appears virtually straight till it crosses the span and then curves up the steep bank, or is this an illusion? ( I hope not because it will fit perfectly where I have it planned if it is as I suspect.)
b) from the photos I’ve found it appears that the river is 2/3 along the trestle with the shorter bank being about 45degrees and the longer one not as steep with the curve being predominently on the steep side…
In the photo below it looks like there are only concrete supports on one side (picture left) of the span, is this correct? I am also assuming this is on the steep side, the other side (picture right) appears to ‘sit’ on the rock.
Many thanks for your help Crandell.
Take care & be safe.
Karl.
Karl, my recollection, reinforced by the photo taken from the top-end, at track level, tells me that if there is any straight portion, it might be two or three bent gaps long, but no more. It is pretty much a sweeping curve with a radius approaching 300m.
The gorge profile is fairly symmetrical in a macro way. I could not honestly tell you what the far side was like because this monster goes on for ever, way off into the Douglas Firs. As for the concrete pylons, I wish I had thought to take note of the side on which I was standing when I took my shot of the lower double Howe Truss at the centre span. (did you get that one of mine?) My mind says they should have been the same, but it appears not to be so.
yes thanks Crandell I got it, it doesnt really matter which side I suppose, just looks like it was only on one side and not both, I guess thats the important point I needed to know. Thanks for the help, I’m guessing these are the pics you are refering to.
Also here is a pano of the river a little up/down stream, is it the same under the trestle. (just hold the left mouse button down on the picture and move it around to zoom the camera angle around, pretty cool)
Thanks, that river question was the last one, I’ll leave you alone now [:D], I ordered the supplies from the LHS yesterday, they’ll hopefully be here by Friday so I’m just gonna build it with the info I have.
Incidentally, I have uploaded most of the Kinsol pics I found to my railimages account, page 9. Heres a direct link if you want to check them out.
You know what? I was wrong. It is a single Howe Truss. Sorry. It is just a very large one, but the structure and the vertical steel bolts make it a Howe, for sure.
Also, that fantastic pano view suggests to me that the near side of the trestle is the steepest, by some margin, and the far side much gentler. Go back and see for yourself.
No need to leave me alone. I will gladly help in any way I can, including a return trip to fact find.
Thanks Crandell that is exactly how it looked to me also, hence the question, I appreciate the confirmation. I guess I’ll look up the diff between single and double Howes at some point but for now I can just model what I see, regardless of it’s name.
Dont be making offers I may take you up on [:D] I could write a list of the questions I could send you out there to answer, such as ; how EXACTLY does the framing transition from the six leg bents over the Howe section to the regular 5 leg bents climbing the hill side, etc, etc…
One thing I will ask though is did you take a pic of the tourist info sign on the approach to the trestle, if you look on my railimages site you will see that it contains 2 pictures of the trestle back when it was in service, they would be great detail photos but I cant see them well enough on the pic I found online. If not, dont worry I’ll just guestimate the cross bracing pattern and other details.
Maybe one day soon I’ll get up there to see it for myself and then I could really get engrossed.
As a matter of fact, I did take a picture or two at that notice board. I’ll post them to you off-line. Not sure if the proximity or resolution of the digital images will be helpful, but they’re as good as yours.
