LGB or Landeck-Graubünden Bahn rounds a corner ...

[rentren]

...under construction. Weather is great! The three links (zig-zags, a glimpse of Mariazeller Bahn) grow between the first layout under the deck and two stacked stations in what used to be a fire wood stack. Will be a while yet before ÖBB 2095 or RhB Ge 2/4 negotiate the climb (aiming for 25‰).
For the pylons I use 3" sewer pipe, raw track bed is pressure treated 3/8" plywood.

Nice to see the pipe solution being used, one I have thought about for a long time but never had the chance to set it in motion. What you using for the track base?

 

[rentren]

Debated track base for long and continue to mull it over. Actual trial will be with what's known in Canada as rolled roofing. Very roughly placed on top of upper roadbed (1/2" x 4" nominally) for illustration.

Called roofing felt in U.K., lots of varieties of the stuff. Works really well if applied like a roofer would using a flame gun, but only for the ecperienced. What concerns me a bit is your use of thin ply, this can delaminate in any kind of damp even so called marine types that only work if they have a regular dose of water proof varnish. Any pin nail holes or screws used to secure track can allow water under the felt. This is true even with larger timber like decking but that will last longer, personally for most of my external wood I was lucky to be given 8X2 inch roofing joists by a retired builder and these have stood the test of time.

Thanks for the pointer! Yes, just 3 plies and some edge separation can be triggered by saw cuts. There is the convenience to lay out track pieces on a 4-by-8 sheet, draw the intended with of bed (defect motor block sans motor) with 'outrigger' chalks. But solid wood, you say, is significantly superior. Cedar would be best then. Thing is, recently prices of structural lumber have shot up by about 1/3, cedar becomes a luxury item.
Still, were I to use fence boards of 1/2-by-6 dimension and assemble trapeze shaped pieces and 'strapping' 1/2-by-4 to tie the assembly, I'd have a more weather proof roadbed. You do send me back to the drawing board, I'm nodding while pursing the lips ...
The heat gun or flame gun is used by pros to soften the felt, I presume, thereby making it more pliable? Best invite my bro-in-law, a roofer, to spend a nice vacation in the Kootenays

Not just soften it, the black glub melts and a quick press down gets it glued in place nicely. Yes BIl would be a good bet. As for the wood, cutting curves out of an 8x4 can be quite wasteful unless you do some CAD work to maximise what you can get out of it. Wood Gravel Boards make good baseboards, generally cheep and tanalised as well. I have also used 12cmx2 cm ones cut in half to make U shaped boards that have been very long lasting with a felt covering just pinned on at the sides. The side pieces give a little extra width if screwed on the side of the top. Allow an extra half inch or so of the felt either side at the bottom to allow for water to drip rather than capillary up to make the wood wet. Curves tend to be made up a bit 50 pence ish in English money with the under supports going across joints. Sharpe curves like LgB R1 a problem but would be fine on your larger radius ones with a few less joints required.

Various building supplies here in the boonies currently limited and/or sporadic. (Can't obtain pressure treaded Oriented Strand Board or OSB which I had also under consideration.) Solid wood (in what I better call my current trial phase, havn't reached the solution) I deployed as 18" long pieces with the narrow side trimmed at an angle to form a polygon when assembled rather than a true curve. I do see how having the track on the ground eliminates some problems while introducing it's own challenges.
So, to continu my day off, I just left Magdesprung (I get a kick out some of your station names like ...Maiden Leap and into whose arms and then note lots of details, e.g. rail clamps. Another item difficult to get here, I have far too little of those but my brother in Switzerland just received an order ...
At run time 08:20 we get a brief glimps of you reflected in the arbor window, no? It's a great Sunday outing! Thanks!!

Yup that is me, generally only me in the linked vids (Trying to hide)! But in my Time Lapse of an Operating session when I complete it on one of my YT vids some other faces will appear. Here is my first test time lapse, overmuch of me I fear!

Puts another item on my wish list.
