Default My First Outdoor Layout

I have started to build my sub Roadbed, and loosely attach track to check the ladders for fit.
The ladders are made of 3/4 X 1.5 PVC trim, PVC cement glued and screwed every 6 inches.
The layout is loosely defined as an L shaped loop
Attached are a couple of pictures, all input and comments welcomed,

Thanks for looking,
Aflyer

Looks good, it is suggested to have a 1' section of straight track between reverse curves. Looks like that could happen where the curve comes out from under tree.

Thanks John,
That is the challenge of free lancing with no software designed track plan. Once I get the straight section down the wall and that 8' diameter circle under the tree I am hoping a nice sweeping curve comes together to join the two.
I also want to add a siding to the semi-straight section that parallels the sidewalk.

Your curve looks really tight. It will limit what you can run.

Mike,
Thanks for the reply.
I completely agree, it is 5 LGB 5' curve sections with an 8' section coming out of the turn.
Too expensive to tear up the sidewalk, LOL.
I plan to run mostly a Consolidated and wood sides era freight cars.

Now I see why you needed the plywood to hold the curve while the glue set.

However, I'm not sure glue is a good idea, and I think your spacers are too wide. The glue issue is purely for future maintenance. A 1x1 pressure-treated wood strip, cut into 1" squares, lets you screw the pvc strip to the wood, and you can unscrew it to make modifications later.
And the pvc strip should be under the rails. Yours seem quite wide apart and supporting the ends of the ties, not the rails. The weight is carried on the rails, and that's what you should be supporting. (The strip doesn't have to centered under the rail, but some part of it should be supporting the rail, not the tie.) Hence the 1" piece of wood as a spacer - with 3/4" of pvc strip either side it will be under the rails.

Pete,
Thank you for your comments, I do appreciate your input.
The plywood jig was something I learned from reading on this forum as well as gluing and screwing the PVC together. I do see your point about the downfalls of gluing it together, and I see as you noted that the ties are supported and not the rails. .

I made the roadbed the size I did intentionally to allow 1/4" space outside of each tie,
I was planning to fill the openings in the sub roadbed and ballast right to the edges of the PVC.

With 48' of roadbed done, I am hard pressed to rip it apart and narrow it, but will give it some thought.
Thanks again,
Aflyer

Don't take it apart. It will work fine. My comments were for your phase 2 track - and there will be a phase 2, I bet.

Pete,
Ha Ha, maybe the siding(s) can be the first phase 2, LOL.
Thank you,

I like how you are placing your track up in the air on plastic. I put mine on actual stone ballast and the weeds were a pain in the butt. Actually gave up on my layout for a few years, getting back into it soon.

If I were to add any suggestions it would be to add a passing siding on the inside of my main line. Couple of switch really add a lot to a layout. A nice train station would look good on this siding.
