I am currently planning an HO layout transfer from my parents basement to my new house that actually has a basement. My basement does not have the square footage to rebuild the layout in its current configuration, so I was thinking of a possible double or even a triple deck design. Has anyone tried a triple deck and what would be the recommended heights and spacing? My idea was a possible double deck from floor supports and then the third deck would be suspended from the rafters. I have never tried anything like this before so I figured a forum shout out might be a good idea.

multi-deck layouts need to be designed as multi-deck layouts and actually require more space not less space. They require more space because they need length to reach the next level with a practical grade (typically < 2%). And much of that length needs to be level so that cars don't just start rolling.

A triple deck layout has a few constraints: 16" between level, leaving 12" clearance between levels is a minimum if you used two foot wide benchwork.
Starting 30" off the floor for lower level, definitely need a chair to operate. Thirty two inches up, to 64" above floor, need something to stand on to work on layout, and perhaps to operate. Needing both means you did wider aisles, eating up some of the advantages you are seeking.
Think carefully and good luck. Keep us posted.

Not only that. The height of the upper deck often narrows the "reach in distance" compared to the same trackage at a single level. And similarly the lower level of a multi deck is often so low as to make the far reaches not easily visible. And as Tony Koester has pointed out, care has to be taken from an operating standpoint not to put two "interesting/operationally intense" areas at the same place on the two levels. The widest aisle in the world is no help if two people need to stand in the exact same spot at the same time.
Speaking as a tall person I cannot say I am a big fan of the kind of double or triple deck layout that seems to get so much attention in the model magazines these days. I do see the advantages of having "passive" staging yards on a lower level because you can avoid the disadvantages of true hidden staging - I for one don't even see what's going on on that lower level!
One possible solution - the mushroom design, where the two levels face opposite directions, and generally a platform for operators is built for the taller of the two so that in practical operation the operator is at the "same level(s)" vis a vis the layout on both sides. But that can require even more acreage and a taller basement than most. And you still need a way to get from one level to another, either the slow and gradual grade or the blob-ish "helix."

Definitely need to design the layout to be multideck, not just fold over an existing layout.
Everything's a compromise - if my garage was alongside my house instead of taking up a huge chunk of what would otherwise be basement, I would easily be able to meet my goals with a single deck placed at an optimal height. But it's not like that, so a double deck is what I need. Neither deck will be at an optimal height, but both are workable - I'm going with 40 and 59 inches, which is 16" from the top of the lower deck to the bottom of the upper deck benchwork. There is no set answer to the height question though. It depends on how tall you are, and how accessible you want the layout to others who may visit or run trains.
Triple would be right out for me, although I do have enough celing height to run a level above the second deck, wince there is framework there to support the second deck's lighting anyway. For 'hidden' staging that would work, same with putting another level below the 40" lower deck - but it would be far too low to actually operate. As 'hidden' staging it would be great. But I also have a requirement to allow storage under the layout, and adding a lower staging area would interfere with that.

Although I do agree with Greg, it going to be hard to cut up your excisting layout to fit a smaller space. Redesign and building new might be the way to go.

My grandpa has a garage layout that was suspended from the ceiling like that, and it did hold up for more than ten years, but it was always quite flimsy. We have had to be careful not to lean too hard on it as it tends to wiggle and I wouldn't trust it. Just saying that idea is possible but maybe not ideal!

Thanks for the replies gents.......I knew there was a wealth of knowledge to be heard. A few details that I hadn't thought of have pretty much put the kabosh on the tri-level idea. Mainly the "reach in" detail that I could see being a real headache from constantly bumping my forehead. I can feel it now and would rather not deal with that. Although I hate the idea of a complete redesign, it might be my only shot unless I eliminate the newer addition I added a few years ago. I think another trip back to the old basement for more detailed measurements might be on the work order this weekend. Many thanks to the forum members.
Rich,
I have a triple deck layout. It is basically a double deck with a lower third deck staging area that is not intended as part of the visible layout (see the link below my signature). I wouldn’t have wanted any more than two visible decks due to the deck height issues.
In general, there are some very specific reasons for building a double deck – mainly operators looking for more run in a space. That was my motivation.
More than a decade in on my project I would say that unless you fit that specific category or have another compelling reason, I would recommend avoiding building multi deck layouts. My experience is that it is more than twice as much work to build a double deck than building two single deck layouts of the same total square footage.
There are lots of stages of construction that must happen in certain order – things like wiring, roadbed, track laying must be done and completed before you can move to the next step. I had to pull extra motivation and some help from my friends to power through certain tasks after the initial excitement had worn off.
I would design a new layout using parts of the old one where you can and keep it single deck unless you are an operations guy.
My two cents,
Guy

Triple deck... not for me, ever. I am opposed to double deckers.
Mushroom layouts look like fire traps to me. If you go that route please invest in a fire suppression system.
-Kevin
Living the dream.
I have a triple deck mushroom layout.
The nominal deck heights are 42", 62", and 82". The top level is viewed/operated from a center platform that is 30" above the floor so its relative height is 52".
There is about 17.5" separation between the rail and benchwork above.
I have a 37.5"/40" radius double helix to connect the lower and middle levels and I have an 84 ft 'nolix' between the middle and top levels.
A triple (or double) deck layout is not for everyone, but mine allows me to accomplish my modeling goals.
Fire trap? Ha.

I don't get the "fire trap" thing Kevin.
My previous double deck layout was also triple decked if you counted the hidden staging.
My visable decks were sataggered in height to help with the transitions between levels.
The staging level and lowest visable level was at 30" with a upper level above the visable 30" level at 48".
The other visable lower level was 38" with the upper level above those areas at 52"
I was not happy with it, I will never build another multi level layout.
I think the fundamental thing about multi deck layouts is your feeling and approach to scenery. If you are happy with the scenery concept of a narrow shelf, then you will likely be happy with multi decks.
Sheldon
mbinsewiI don't get the "fire trap" thing Kevin.
The mushroom layout designs I have seen usually have a long path to get to the top operating platform for the mushroom section. This usually limits all pathways of egress in case of an emergency. If a fire starts almost anywhere in the layout room, you could easily be trapped in the mushroom.
I had a fire in my house once, and it is one of those things you need to experience to believe it. Your body will not let you do anything that will get you closer to the fire.
I have fire extinguishers everywhere now. Next time I will have a weapon.
If I had a mushroom, there would be something in there to suppress a fire.
ATLANTIC CENTRAL If you are happy with the scenery concept of a narrow shelf, then you will likely be happy with multi decks.
My experience with multideck layouts has been that the scenery on the lower portion almost never gets worked on. Many end up only being operated on the upper level, and the owner is not satisfied.
Keep in mind, I do live in a retirement area, and my modelers here are advanced in age, so ability becomes a challenge.
SeeYou190I had a fire in my house once, and it is one of those things you need to experience to believe it.
I get that. We had the second floor of our house severly damaged by a fire, back when I was a kid, and along with all the brothers and sisters, lived at home.
Later in life, I spent 15 years on our local FD, going into structures on fire, also a state certified instructor, working for 2 local community colleges.
Just wanted to know why you thought what you did.
PS. You did some editing while I typed.
My father was a volunteer fire fighter, my son has been both a volunteer and paid fire fighter and is now an EMT. I passed on that hobby/occupation.
Anyplace that is too much of a "maze" can be a fire trap, no question. New homes around here are required to have sprinklers, but there is no retrofit requirement.
Even with my new single deck layout, I have no interest in floor to ceiling "isolation" backdrops that create the maze effect in the train room.
I understand the theory of creating a greater sense of distance, but would rather the room be open for a number of other reasons. Another reason to get away from multi deck designs as they tend to require the maze effect.
SeeYou190The mushroom layout designs I have seen usually have a long path to get to the top operating platform for the mushroom section. This usually limits all pathways of egress in case of an emergency.
Overly broad -- and inaccurate. There's a wide variety of mushroom designs, and none that I've seen (or drawn) "limit all pathways" of egress.
SeeYou190My experience with multideck layouts has been that the scenery on the lower portion almost never gets worked on. Many end up only being operated on the upper level, and the owner is not satisfied.
Again, not accurate as a generality. I've visited, operated on, and designed dozens of multideck layouts which have scenery on upper and lower decks.
If you don't want to build a multideck layout for yourself, perfectly fine. But many folks build, scenick, and enjoy them.

No more true for multideck than single-deck.
All the hand-wringing about multideck layouts in a fire seems overwrought. I’ve never heard of a fire starting on a layout during an op session or open house (or really, any time). But houses do catch on fire and take the layout with them.
Kitchens are the most typical place for house fires to start (~50%). Would you buy a house without a kitchen to cut down the risk of fire?

+1 It would have to be a very explosive and extremely rapidly spreading fire.
The sense of isolation is why I built the extra wall full height, instead of just a half wall. If the top was open with no scenic divider, then someone running on the branch at a location that is about 15 miles as the crow flies from the yard which is on the other side and across the aisle would be able to see that yard. That to me ruins all chance of illusion. Instead, that branch crew will be out there on that side of the wall all by themselves, working to the end which, being all the way over by the door, is going to be quite isolated from anyone else running a train. Out in the country with nothing but wildlife and an occasional farm around. Riding on that very branch even today, in a car filled with others, still feels a bit like that. One of these days I may spring for the caboose rental (flat fee, can take as many people as fit - so it doesn't matter if I spend that money and then ride by myself, take 2 friends, or 6 friends) and really get a feel for being on a lonely single track railroad with no one but the crew around.

I know, we have had this discussion before.
Like I said, this is retirement central down here. People move here and have ideas of building that dream layout, then more often than not, the lower deck gets ignored.
Then, if you develop mobility issues, the upper deck becomes off limits.

I can only talk about what I have seen. I have never seen a fully armed and operation double deck layout in someone's home.
cuyamaKitchens are the most typical place for house fires to start (~50%). Would you buy a house without a kitchen to cut down the risk of fire?
Interesting, unfortuately it is not an option. In Florida you cannot get a primary mortgage unless there is a fully functional kitchen.
My kitchen cost me $22,000.00, and I would have much rather had that 110 square feet for the layout and spent the money eating out every day for years. Unfortunately that was not an option.
The house fire I was in did start in the kitchen, but it changed my entire way of thinking.

Byron,
I asked my fire captain friend of mine about this issue years ago. He laughed and said that model railroads are not the hobby firemen worry about.
Its car guys with their cans and barrels of solvents and paints that give them pause....
trainnut1250I asked my fire captain friend of mine about this issue years ago. He laughed and said that model railroads are not the hobby firemen worry about.
My understanding is that most deaths in house fires hppen when the fire starts while you are sleeping. It is very doubtful that you would be asleep in the layout room.
Maybe over-cautious, but still a concern.

Kevin,
I dont see that many layouts that are complete regardless of design or number of decks. I would suggest that most layouts in general don't get finished and that there are big sections that aren't done even after many years. Double decks wouldn't be any different in that regard and it is likely that the bottom deck would be the last part to finish.
I have seen many double decks with scenery on both decks in my area - Jack Burgess, Dave Adams, Jim Vail (gone now) Tom Ebers and myself to name a few. On some of these layouts (including mine) the bottom deck is the last part to be scenicked.
I suspect that the price of real estate and lack of basements makes double decks more common in the West and you are more likely to see more complete layouts as a percentage. If I had the space to get a long mainline run in a single deck, I would definately have a single deck layout.
ATLANTIC CENTRAL I think the fundamental thing about multi deck layouts is your feeling and approach to scenery. If you are happy with the scenery concept of a narrow shelf, then you will likely be happy with multi decks. Sheldon
Sheldon,
Agreed that it is a generally a different concept of scenery.
There are some interesting ways to deal with that issue - one is the view from one scene across the aisle into the other scene can create more depth.
Another is there can be areas where the layout is single deck with deeper scenes. Usually there are parts of a layout - say over the 6 foot diameter helix are deeper and that create big depth. I intentionally left my yard single deck and it can be viewed from the end into a 13 foot long scene.
Another fun thing to explore scenically is having the scenery right at eye level changes the perspective and makes it possible for visitors to see detail in models that they might miss if they were looking from above.
trainnut1250I dont see that many layouts that are complete regardless of design or number of decks.
I would guess that I have visited 15-18 completed layouts. Every one was single decked.
I would guess I have visited 5-8 double deck layouts, all had the lower deck in a state of permanent stagnation/neglect/unused.
Again... elderly retirees with big dreams and oncoming mobility issues.
trainnut1250Most layouts in general don't get finished and that there are big sections that aren't done even after many years. Double decks wouldn't be any different in that regard and it is likely that the bottom deck would be the last part to finish.
Yes, exactly. The bottom deck gets finished last, but the owners around these parts physically cannot do it, so it never gets done.

I am not "In The West", I live on the West Coast of Florida. Florida has five coastlines, and we all think the other four are inhabitted by weirdos. It is a Florida thing to specify what coast you are from. Now those "Central Staters" that live in Orlando... that is another story.
Anyway, we do not have basements or attics, but believe it or not, double deck designs are not very common. Most layout are built in a 150 square foot or so spare bedroom, and getting a helix or no-lix in that space is a challenge.
The garage is where I see the most double deck layouts. The garage can be a poor choice of layout location for a number of reasons.

I took all that into account when I built my double deck layout. I had two peninsulas that only projected 6' out from what was otherwise an around the room layout in a 25 x 40 room.
The two peninsulas were lower in benchwork elevation than the decks around the room and were used as the transition between decks. There were no backdrops on the upper deck of the peninsulas. I did not use a helix. My minimum radius was 36", so the peninsulas were 7 feet wide.
So this kept the room open at eye level, and provided some areas with deep, expansive scenery.
But as construction progressed I was less and less happy with the lower deck, even with a fairly generious seperation and shallow shelf dept.

Well, I have visited easily 100 layouts, most were 85% or more "visually complete", be they double or single decked. Many fill basements of 1200 to 2400 sq ft, so I don't see the connection to the idea that these larger layouts do not get completed.
I have never lived out west, never visited any model railroads out west, never spent any measureable amount of time west of the Appalachian Mountains. So all my layout visiting experiances are based here in the Mid Atlantic, where most houses for those of middle class means have basements, or over garage bonus rooms, etc.
And where some notable modelers have built large out buildings or expanded their basements without expanding the house above to house their model railroads.
And while basements are the obvious location of many large layouts in this region, you might be surprised how many are in outbuildings, or purpose built above grade additions.
My old layout was above my 6 car detached garage/shop. My next layout will be in the 1500 sq ft basement of my new to me 1964 rancher.
Kevin, what about people who live in Okeechobee?

Maybe I should have been more specific, I was refering to layouts with floor to ceiling walls as peninsula backdrops/supports.
Yes, single deck layouts can be built that way also, but I have not seen very many.
I understand all the reasons to build the floor to ceiling backdrop wall like Randy is doing, I just don't care for it in most cases.
My new layout will have two peninsulas and use a combination of low backdrops and natural scenic features to separate one side from the other.
I like being able to look out over the whole layout. On a similar note I would never put a dispatcher in a separate room or secluded spot.
For me, some of this illusion of distance is better done in my imagination.
