after much consideration and encouragement from otto, cajon pass is not fully dead. I have found a way to make it work better in the basement but ill have to view the eastbound traffic coming up the pass from the opposite side if I go this route. otto also suggested modeling the east slope but im not sure if I like that as much. it WOULD make operations easier due to the fact that most helpers were on the front of trains vs the rear or even mid on the west slope. ive been looking through my books for inspiration but I keep being drug back to the west side as its what ive always been intrigued by. we will see what I come up with.

I have on the other hand bought some square tubing to make a floating summit that will span 10 or so feet from wall to wall. imagine the benchwork being the hypotenuse of a right triangle yet the benchwork is only an inch thick, is 2ft wide and spans a 10' span with no other support besides at the 2 walls. is should make room for a nice helix underneath that otto hates lol. hopefully ill get to making this piece sunday and try to get it test hung.

The new location of summit on my cajon pass has been set. The benchwork is a 1"x16 gauge steel tubing all welded construction. The weird raised section on the back is actually a spine brace that helps hold the section out floating in the middle square. This may sound weird but i actually designed this in and twisted the frame work out of level when fabricating this so that it would level out once hung. Its like the semi trailers that look bowed up empty but flat when loaded.
Im extremely pleased with how solid it is only mounting to the walls with no needed support from the floor or ceiling in the middle.
Now it's time to start moving the existing benchwork back around for the new design.

Upper level is summit and east to staging or maybe victorville.
Lower level is cajon or sullivans curve to alray/ entrance to tunnel 2. From tunnel 2, it will be a 16" climb up a dreaded but exposed helix to summit.
I'll be able to view Sullivan's curve from the spot most everyone takes pictures from which is a big plus.

Ill share a rough plan later today.

 I'm impressed with your welding skills, Adam.  :P :P I really like the way that welded frame looks hanging there. Can't wait to see it with track laid on it.

Thanks rodney!
Im thinking of going with metal benchwork all the way around! $0.84 a foot and it's lighter than what it would be made out of wood and of course it's stronger not too mention it won't sag over time.

The reconstruction is taking place. The old summit has been dismantled and the lower and upper levels are progressing from left to right. The new summit is ready for track and the helix has started!
Ill be using 28" radius kato unitrack on the helix. The rail will be replaced with flex track so i have fewer joints and hopefully smoother operation. The unitrack sections will be easily removable for maintenance.
The grade in the helix is 1.5%. Hopefully i can finish the helix before i head out of town for work again.
