I am looking to build a small portable HO layout to take to shows. And while the train/track part will be vintage(more on that in a moment), I would like the base part to be as lightweight as possbile so I can manage it mostly by myself. The only think I can think of is a hollow core door with fold up legs mounted on the bottom. I am planning to use old school true scale self gauging road bed(already have some on hand) for the outer loop(18" radius curves). This will be the outer loop around the edge of the door. I am then thinking a 2" thick pink foam raised center area where I will put my logging camp and mill. A steep connecting track will be cut into the foam to connect the lower loop to the logging area. The incline and upper area will be built with older Atlas snap and flex track. Motive power is all older brass. 2 PFM 3 truck Climaxes for the logging part. An MB Austin SP 2-6-0, PFM ATSF 2-8-0 and IMP ATSF 2-8-2 for the branchline that loops the logging area. I am planing to use all older/vintage kits for the buildings such as Suydam and others from the late 1950’s and 1960’s. I find that whole era of model railroading fasinating and enjoy hunting for and enjoying the models of that era. Open to suggestions and ideas if I am missing something or you have a better idea. I have a full size pickup truck, so a normal height interior hollow core door will lay flat, on end will have to keep the scenery lower so it can slide under my tool box. Mike the Aspie
Sounds promising. I’d recommend doing some rough calcs before starting. Here’s a chart for door weights:
http://www.incpark.com/mohawk/pdfs/general/sizenweights.pdf
If you use a 1 3/4 x 3/6 x 6/8 door, it comes out at about 37 pounds. Going down to a 1 3/8 thick door saves you 2 pounds, but you get a wimpier platform.
Mounting the fold-up legs might be a problem, as most of a hollow core door is, well, hollow. Not good for mounting. And you should add the weight of the legs to the overall weight.
You’re going to have to manhandle this thing. As a Free-mo guy, I get to manhandle modules. Something that big is gonna be a pain. But there’s a real benefit in having it be one piece.

I have seen guys mount the legs by putting 1x2 boards across the bottom to bridge the open middle area and provide support and means to screw the legs down with drywall screws. Also thinking that a couple of nice brass grab handles along the edges will help with the “manhandling” needed to get it moved. I can fit 8 foot in my train room, but its really tight and hard to get thru the hall door. Buildings will be mostly removable with either quick connects or other means for lighting. Mostly just clear xmas bulbs mounted to the foam upper level. Wont be that many anyways. Probably a Suydam sawmill at one end, and a small town at the other end. Maybe an engine house/servicing area near the mill. Looking at door prices. I have enough truescale roadbed to do a loop around a standard height interior door. Other option is to cut the door into 2 seperate sections, make interior support for the cut area on each side. I have seen that done as well with a one man portably set up at shows. With grab handles, he did manage to haul them in and out all by himself. That would keep the weight down. He just set his sections on a show provided table. No legs on his set up.
Install some metal handles on the back. So it will be easy to carry with one or two hands.
I thought of this idea but it was too late to install.
How small is small?
Portability is not only a question of weight, but also size.
A hollow core door, though not really heavy, still has quite a weight. The utmost in lightweight benchwork is a sandwich consisting of 1/8" hardboard, 4" foam, and another 1/8" hardboard. This consztruction is surprisingly sturdy and weighs close to nothing!
Here’s something we did to a grooup of the club modules that happen to all be the same width. Since they bolt together end to end with carriage bolts and wing nuts, we made 2 panels of plywood, with a strip of 1x3 or something across the bottom. Holes are drilled to match the holes ont he 4 module sectioons. The extra piece of wood on the bottom gives room to mount 2 casters on each plate. For transport, the modules are bolted tot he plates and, via a rope run through one of the end plates, pulled to where they need to be. A handle on each end plate allows the whole thing to be picked up easily by 2 people - the modules are too long for one person to possibly pick them up.
The legs detach fully and are carried seperately. However, for a 2 module setup, the legs could be made fold up and the whole thing fit together the same way.
The majority of the other modules, they fit in large racks we made with 2x4 frames and large industrial casters - these get carried in enclosed trails towed behing members’ pickup trucks. Some have attached foldable legs, others have removeable legs that fit in pockets underneath the module. The legs fit in trays in the bottom of each rolling rack along with other miscellaneous equipment. Just have to put that stuff in before loading the bottom module.

Standard door sizes
https://www.remodelingexpense.com/dimensions/standard-interior-door-sizes/
Widest “standard “door shown 36”. Not wide enough for 18” radius. Have found doors 42" wide on-line
doors ar actually quite heavy. Lighter construction is possible.
One idea

A fellow from a club that displays module layouts at shows (lots of travel and set-up, tear down) posted a message and a photo on one of my subject threads,… with a description of their building process, but I can’t find it at the moment.
That sounds like a winner,…and easy to construct
I wish my train room was more conductive to a portable set up. Its a whopping 8 foot by 9 foot. So even the standard 4x8 layout is land locked at one end with only the one long side accessable to work on the layout. I have tossed around an around the room set up with one portion removable for shows, but there are two doors, both in the same corner, that open into the room. Solving this problem, let alone building it constantly overwhelms me. I so need someone to come in and build the benchwork and get me up and running. Benchwork and track plans are my struggles with trying to build a layout and being autistic. Give me a brass model to rework and fine tune anyday. But building and solving bench work and track plans that actually fit the space I have is beyond me. I do like that table bench work pictured above. But with my small room, a full blown table, unless really narrow, isnt gonna work. Around the wall works better, but that is gonna take some help from others to construct
Waffle-style benchwork is stiff and rugged, relatively lightweight, and may be easier to wire than sandwiched foam.
If it is 3-6 x 6-8 (same as the 1 3/4 hollow core door mentioned earlier), it will weigh 38 pounds. About the same as the hollow core door. If you substitute 1/4" ply for the 3/4" ply end plates, the weight would go down to 35 pounds.
4" thick foam with 1/8" ply on both sides will weigh 23.8 pounds
Above calculations based on closed cell foam weighing 1.7 pounds per cubic foot, 1/4" plywood weighing .69 pounds per square foot, 3/4" plywood weighing 1.9 pounds per square foot.
This is for the basic “module”. Without legs, other hardware, scenery, track and electrical.
Ed
For a roughly hollow core door sized layout, I have used more like 2" depth rather than 3½". If not a module, no need for the heavy end plates, as you point out.
Personally, I’d rather not try to wire through a plywood-foam-plywood sandwich, but everyone makes their own choices.
Edit: By the way, although it’s a bit expensive, I’d like to try waffle-style benchwork made of Gatorboard for my next small switching layout. It seems to be relatively light and still pretty stiff. Greg Johnson has used it to build sections of his layout with good results.
I get 28.5 pounds by thinning overall thickness of ply-waffle and using 1/4" endplates.
But it’s only 1/4 as strong. Or worse. But all it needs to be is strong ENOUGH. It may be that the “standard” ply-waffle design is overbuilt.
For clarity: Free-mo requires 3/4" end plates so that modules can be clamped together with C-clamps. If you’re not doing Free-mo, no need.
I suppose I should mention that Mike could build Free-mo module(s), and then come and play with the other kids (include his modules in a Free-mo setup).
Ed
That’s my experience – at least for a small standalone layout. One needs the beefiness for modules because of the strains of shifting a long chain of clamped-together modules (among other things).
Probably going to just do away with the portablity part and look for help to finish the shelf type benchwork in my train room. My one engine needs a 36" min radius to run, so flex track will probably be used on one part of the layout. The lines to the woods logging camp will be tighter as the will be worked by a smaller Mallet(2-6-6-2T) or the 3 truck Climax. The monster mallet(2-8-8-2) will be mostly staged on the main and run a short distance to a hidden staging area to simulate the run to the Longview, WA mill. As the motive power has come together in the last few hours, so does the plans on how the layout will evolve to suit them. Thanks for the help guys, lots of good ideas I can use in many ways

Just want to say that I find your concept of using only early models from HO’s formative years is really intriguing. I would never have thought of trying something like that, but would be very interested to see it done. So, am wishing you well and hoping you’ll have photos to share some day.
Thanks, I have found a nice little 4x6 layout that has scenery and such locally for sale. Waiting to hear back from the seller to see if it still available. It would fit nicely along one of the walls and have access on 2 sides vs 1 side on my current set up I have. While not a logging layout per see, it would fit my small SP engines really well and allow me to stock pile the logging stuff for a future set up. Now if I could just find the C10 2-8-0 that MB Austin imported around the same time frame as the M21 Mogul I have now. Mike the Aspie
If the 4x6 falls through, you might consider a table top modular concept similar to T-trak.

This can be adapted to HO scale.
Use steel studs, luan plywood and 2"styrofoam.
