Don’t watch this if you are bothered by heights. If you do watch it, listen for the trestle creaking about 35 seconds into the video. I shot this on 9/30 on the C&TSRR.

Here is another clip crossing the same trestle – but heading east toward Osier.
Looks like fun!

Thats Cascade Trestle. To show you how high up you really are:
it’s a little over a mile west of Osier. Thats D&RGW 315 up on top.
YIKES! That is a long way down. I could do without the creaking.
That must have been a nice rail trip.

I was kinda wondering where exactly that was. It’s been a looooong while since I’ve been out there…
Very nicely done. Love the RR drama out West. Gonna have to visit some time.

Very spectacular .
The upright supports remind me of Radio Masts ; I don’t recall seeing the taper down to the base used elsewhere except on Radio Masts where the whole thing rests on a large steel ball bearing , hence the taper . This allows a bit of flexibility in windy conditions .
Was there a special reason for this design ? It does allow quite a bit of movement in earthquakes , but I can’t think of any other reason.
I would really like to cross that on the same train . Great .

Because when a design has been proven, and the engineers can’t think of a better one, you go with the proven design. 
Its been done that way since Cheops’ time. 
Look Steve , I was around when Pontius was a pilot , so I know that .
What I meant was why there ?
Mike
'Cause they couldn’t think of a reason why not?
'Cause it was their Senior Project?
'Cause the Boss said so?
'Cause it was the cheapest?
That last was probably closest to the truth.
Actually , it’s unusual enough to have been some odd project that was dropped by the military and sold cheeeeep .
And probably all of the reasons you give above .
Mike ; not a builder of bridges
If I was riding a train over that trestle I would have aged about a year when I heard that creak!
