Goodbye theater, hello layout.

Excellent answer, thank you. I will most likely use both methods and try to stick to dimensional where it’s easier and flex for more “flexibility” in the trickier parts.

John is right about both points.  I used a minimum at flex on this layout after butchering several pieces trying to get around a jog in the room where I built my Ceiling Central Railroad.  I do have curved sections left over, mainly because we originally designed the layout for 042 on plans A, B, and C, then changed to 054 on Plan D.  I also bought some very nice used 064 from someone thinking they were 054.  I don't know if it was my mistake or the long forgotten other guy's mistake, but I have a lot to inventory and offer for sale.  If I had used flex throughout, I would be able to use the left over for another 11-foot long display shelf instead of having to buy more straight for the shelf. 

Once you bend some, it gets easier.  Obviously, the tight curves that Tom was talking about in a different thread are a whole different deal, those must be fun to bend!  The tightest curve I'm bending is around O80 and up, not too bad with new track that the ties slide well on.  I'll probably have some Ross O72 left over, I bought 75 pieces when I was planning on mostly O72 curves.  When I decided to go bigger, I just used a lot of flex track for the larger curves.

We used all dimensional tubular and Gargraves track in our new layout on about 95 percent. Some of those pieces were bought off of forum members who chimed in elsewhere in this thread. Glad they switched to flex...I got a good deal on sectional because of it!

The other 5 percent we used flex. I think we used 4 pieces of flex in all.

Something to consider, if you truly want your track "straight", buy straight track. Although the flex starts out as straight, the moment you bend it at all is the moment you might as well forget about it ever being truly "straight" again. You can do it, but not very easy.

But the flex pieces were handy when having to do little "jogs" in odd dimensions. I didn't make any into true radius pieces though.

Amen to that.  In fact, I think it is next to impossible to get them straight again. 

I’m very open to buying leftover pieces of track from forum members. I have about 20 foot of MTH set up right now with an O-72 curve in the middle for testing  and I’m not very happy with it. If you have track to sell, send me a message.

David, I'd reconsider used track.  Since I only had minimal exposure to Gargraves Flex before this layout, I bought some pieces early on just to see how flex would be to work with, and get some practice.  Old track ties get brittle and hard to slide, making it more difficult to easily form proper curves.  That also have a tendency to kink or twist much easier than new track.  It's workable, but since the track isn't that expensive for factory fresh, I recommend going that way.  The new track is much easier to slide the ties and make smooth curves.

I agree, but you can come pretty close.  I have a 3-track yard hidden behind my grade, I'm thinking of using the older track that I practiced on for those tracks.  I managed to bend them pretty straight, certainly more than sufficient for a yard.  I'll see how my track supply is running as I get nearer the end, if I'm running short, I may use them for those yard tracks.

Just wanted to say that I like your track plan. The folded dog-bone as they call it is my favorite type of track plan. I like that you can pretend the train goes somewhere (leaves a scene) and then comes back from the direction in which it left. I understand if you don't want to do any switching (hey it's your railroad) but I highly agree with the suggestion to add some passing sidings. For me a circle, even a giant circle of track will get boring after a while. If it hasn't been already suggested you could add staging tracks for full trains so you can easily switch trains. There is no right or wrong way to do this hobby. All opinion. Good luck and have fun.

Good point on the used track. Thanks.

im thinking of adding a wye dead center in the top that will go nowhere for now but will basically point to the center of the room. That way I can turn trains and it leaves me open for a peninsula yard if I want in the future.

David,

If you are dead set on using older GG track, whether it is used or NOS, buy a big can of WD-40. Spray the wood/metal contact points, and let the sections sit a bit. I let mine sit overnight b/c I had other things to do. The stiff joints really soften to a point where the ties will easily move. Be sure to wipe the rails down before moving on. It works.

Still pretty undecided on the right side (per pic) of the layout but the left side is pretty solid. Sold the two arcade machines this morning so that made it easy to go buy some wood with the “free” money from them. Built some bench work and quickly realized how different it is to see this in person as opposed to a screen. Amazed at how much real estate even an O-72 curve takes up. Let alone that that will be my minimum. Also amazed at how hard it is and how much time it takes to find somewhat straight wood at the big box stores. What was straight when we bought it was twisted up when we got home. Not a huge deal but took longer during building to make things straight. You also quickly learn how not straight and square your house is!

I built it all in modules so it can easily be taken apart if I change my mind before anything is made permanent. I’m more of a visual person I guess so I had to build something to see the vision as I was  getting frustrated with paper and screens. Biggest decision now is do I shorten the left side as it’s shown in the pic or go the full 25 or so feet which means hole in the lower wall as the space is only 6 feet wide. Hate to give up that space when all it means is possibly drywall repair for the kids when I’m dead.

my very supportive wife used the parts I wasn’t currently working on to set up and do some paint by numbers. Was a pretty good day overall.

It's looking good, David.  Yes the best I could fit in my room was 054 curves!  O gauge takes up a lot of room!

Was originally planning on 2% grade max. Is 3% that much worse? I only ask because the supplier I’ve chosen doesn’t offer the 2% kit. Only 3. I can get the 2 from someone else but they are the same people who sold me the O-72 curves and it took them forever to ship. The chosen supplier shipped my Gargraves track the same day and also answered the phone and were quite helpful. Those are important points to me.

My grades are roughly 2.7% grade and are no problem for any of my engines pulling relatively short trains since the layout is in an 11x11 room.  I don't see any problem with 3% grades if you are running modern engines.  Postwar without magnatraction would be another story.

I have used 2% up to 4% on my layout, work just fine.

I'm at 2.5% grades, and I don't anticipate any issues.  We have a long 2.5% grade on the club layout, and I had two Legacy U-Boats pulling 115 cars around that layout and they managed the 2.5% grade, so my little 23 x 12 layout shouldn't have any problems.

I chuckled at the wood comments.  I took the shortcut around the crooked wood by using the Mianne benchwork for the underpinnings of the layout.  For the top, I used Baltic Birch 1/2" sheets, they're 11 ply and as flat as a pancake.  They resist warping much better than big box store plywood as well.  I had to go to a real lumber yard about 30 miles away to get my birch.  That's topped with 1/2" Homasote for some sound deadening, and the track is laid on 1/4" foam roadbed.

There was one important feature i wanted that the 2% grade would not allow, and that was a reversing switch. Thankfully a 3% grade allows me that as well as the option to not cut a hole in the lower wall if I do not want to. I can only currently fit one reversing switch in which means you have to go all the way around to reverse again but it was a very important feature to me. Now to work on either passing sidings which I love the idea of or a yard somewhere.

I'm not sure why a grade is necessary for a reversing switch.  I have all the reversing on my plan on the main level with no grades.  How does the grade percentage enter into reversing?

The two double-slip switches and #201 and #100 allow crossing between sides of the loop as well as access to the yard and the inner O72 loop.

On another section, these switches allow movement between inner loops and change direction on the main loop.

The grade is needed for the over under on the left side. So the only place I could have a reversing switch on flat ground was where I have it in the pic. With a 2% grade the incline started too far back (towards upper right) to make it happen as I wouldn’t want a switch on a hill.

OK, starting to make more sense, you had me going there for a minute.   Why couldn't you slide that whole reversing part down a bit?  The two crossovers don't have to be next to each other to get the job done.
