There are many factors to consider before we start building a model railroad layout. I know of many model railroaders who have started building without much of a plan and spent much effort and money on their layout, only to realize partway through that they just weren’t happy with their endeavors – and a lot of their efforts ended up in the trash. So… I think planning is very important.
In part 1 of this ongoing series on planning and building a model railroad layout, we looked at the all-important question of “Why do you want to build a layout in the first place?” In part 2, we’ll look at the tactical planning elements of a layout, focusing specifically on your track configuration.

Where should your layout be located?
When the passion for building a layout kicks in, I think the first question should be: “Where?” Finding a suitable space isn’t always easy. An extra bedroom? The garage? The basement? Build or buy myself a building to house my trains?
Then, the condition of the space is important. Is it big enough for my needs? Will the room or building need work before railroad construction can begin? How about the ceiling? The walls? The floor? What about the electrical supply and lighting? Heating and cooling? Do I want a train lounge for my buddies? How about toilet facilities? What will my wife think??!!
All of this may seem overwhelming but remember that this is YOUR layout. You can just disregard everything and forge ahead. Remember that model railroading is and always will be about having fun.
What track configuration should I have?
So there’s a lot to think about. But, once we get past all the preliminaries, we’re ready for the really fun part – the layout design. Steve and I thought we should run through the basic track configurations for those who might just be starting out. This may seem elementary to some, but I hope that you’ll hang in with us.
What follows is a list of nine of the more basic designs, complete with pros and cons for each.
CLICK HERE to download a handy PDF of these designs that you can print out and keep for reference.

OVAL: The most common starter design. Lots and lots of continuous running.

DOUBLE LAP OVAL: Doubles the “mileage” of the oval.

DOG BONE: Great for those who want a more accessible and straighter section in the center.

FOLDED DOG BONE: Dog-bone with center “accessible” area folded around the corner of a room.

POINT-TO-POINT: Most realistic design. You may need turning facilities at the ends depending on your motive power. No continuous running.

POINT-TO-LOOP: Adding a reversing loop at one end enables a return operation. You might need electronics to provide for the resulting mismatch of polarities at the loop.

LOOP-TO-LOOP: Same idea. This provides for continuous running with the proper electronics at the loops.

FIGURE 8: Classic design. This can be done with an at-grade crossing or as an “over and under” plan. The over and under may require some gradient considerations.

FOLDED FIGURE 8: This might enable the design to fit into a larger space.
What design is best for you, your space, and your railroad operations? Only you can decide, but take the time now to avoid ripping it out later!
Next time I’ll discuss “layout elements” that may help you settle on a particular design. Stay tuned.

I need some advice for wiring a folded figure 8 double track
Brand new to model RRing, although it’s been a dream of mine for many years. I bought my subscription to this site in hopes of finding useful information and links but it seems that everything requires more money!. I want to build in N gauge. I plan on a 2′ x 3-4′ space. I want a canyon look with mountains, farmland, waterfall, river, bridge and tunnels. I know this is an ambitious build for a newbie but I have faith in myself. I wish there was more info on inclines, curve radius, power requirements for everything, what can you “get away with”, etc. Yes I’m more interested in the creation of the miniature scenario but I also love trains and want this as realistic as possible. Advice?
Hello Lauri. It sounds like you have a tremendous vision! Let the artist inside guide you.

In the process of building a layout with seven separate loops on a two tier “L” shaped design 10×4 and 14×4
I had started on a layout, but found myself way over my head. The program you’re offering is just what I need.
In full detail please as I have not done this before. Thanks
Just beginning
I would love to join but postage to the uk costs more than I’m buying.
Not your fault I know but still.

Finally getting ready to break ground on Fn3 White Pass and Yukon garden RR using an old John Allen article
Great article! I now am retired and have time to build my fourth layout. So your concepts are helpful! I will stay tuned to this channel.
I am building a G Scale layout. My table i9s 6’6″ x 12’6″ with 24″ radius corners. Can you suggest a layout that will maximize the table and be able to run some different size or types of G scale trains. I’ve been trying to come up with a layout but i’m just not sure. Any help would be great!!!

I am just starting out planning my 0 gauge design. I like the Dog Bone and Folded Dog Bone but want to add a second set of tracks – one for freight and the other for passenger. I was also thinking of two levels alternating which set of tracks is on the lower level versus the upper level. Open to any ideas. Bob
I failed to mention that I use the old O27 tubular tracks. :)
Well, in the intervening three years, I’m sure you’ve come up with at least one solution, if not several. For others in a similar situation, adding on to O-“Gauge”, (not O-“Scale”), I would suggest you look into GarGraves track. The center rail is black and the ties are much more realistic. You can buy switches in different configurations & etcetera. Happy “High Railing”.
Hi, I am starting out with a layout in O scale that is similar to the “Double Lap Oval” that is on a 4X10 trainboard, and what I would like to ask is will it be necessary to add supply wires to the track via buss lines to maintain steady flow of power. Currently have a 50 watt transformer, locos from my younger days (circa 1954) and a new MTH SW 9 Protosound 3.0 Pittsburgh and Shawmut (30-20491-1) and was wondering if I needed any special wiring setup to run this. Thanks in advance for any help and advice.
Hello Francis,
The use of buss wires and multiple feeders is a good idea in every application. They provide an even voltage everywhere on the layout. Rail connectors can create problems with current flow over time.
Hope this helps,

I like the loop to loop configuration. I control the polarity on mine with relays, and use spring switches for the loops. I think its more visually interesting, to have the trains run both ways on the same stretch of track. And those who have tried, and failed, to use reverse loops, are memorized that I have 2 of them and they just work automatically. Add to this that I am doing this in large scale, in my backyard, while bridging a pond and meandering through a forested landscape, just adds to the wonder and charm of my semi-fictional short-line.
Looking for ideas for my HO scale 15 by 17 foot layout in a separate room of my house.any ideas would be great.
Hello Robert,
I would recommend looking into an around-the-wall layout to get the most distance out of your main line and allow wider radius curves.
Hope this helps,

Have my father’s trains, must have thousands of dollars worth. Would love to get started to put it all together.
I am very unhappy with your publication.
I am a Premium member, and most of your emails are for selling videos
at ridiculous prices for vastly discounted amounts,
wanting to goad me into buying a lengthy video, or six.
On top of that, I get daily invitations to purchase your “Gold” plan,
presumably to get more enticements to purchase videos.
This is not what I expected. I expected many helpful hints for building
a new layout, at the Premium plan level. In fact, had I known about your
so-called “Gold” plan I would not even have joined the Premium plan.
Your entire marketing campaign is a come-on.
I will not sign up for more plans.
Your publication is not worth the money spent on it.

Would like to build a ho layout on a 4×8 table with a golf course design on the table
Duane
Hope to get some good info
What is the smallest switch size(on the market) to make a compact yard mostly to show off rolling stock?
Hi Penny,
Generally, the smallest frog size commercially available has been a number 4. But, if you run modern freight or long passenger equipment, a number 4 may be too sharp, especially if you end up with S curves in your yard ladder.
Hope this helps,

Hi I’m Dene. I’ve built a few layouts in the past 30 odd years, but the latest one, I have constructed the baseboard table Wichita lowers from the roof of my garage with a 3 tonnes winch and I’d like to purchase track layout planning DVD’s, but you don’t send to New Zealand. Bugger, what can be done please !
A’ve a really nice day Dene.
Hi Dene,
You are in luck, we do currently ship to New Zealand. Hope this helps!

Do ;you have any diagrams for using 2 separate tracks? Want to design a layout w/ a passenger line and a freight line.
Hello,
Well, there first thing is to decide have much space you would like to use. And then, what scale? There are some good track planning books available on line.
Thanks,

all in all a great job and good info as always.
I’m starting a new build in ho, just figuring out what I want to do in the garage, my space is 14 X10.
About to dismantle/reconfigure my layout, but it’s always good to start with “basic training”!
Hi ,i,m building a 4×8 layout in ho.This is all the room i have.and then theirs the wife.but we will not go there.i bought a atlas figure 8 track plan.I want to do it right. The plan will give me a good start.i feel this is the way to go if you are a beginner.Or if you are like I em can,t plan my way out of a paper bag. the atlas track plan come with all you need,exept the system you want to run trains with,dc. or dcc..So this will be good for all of us. Beginners and vets. And don,t for get what ever you do have fun and run trains. Trains 62 out.
I was hoping to combine HOn3 lumber operations incorporated into a more mainline HO layout. In addition, I would like to run dual track at some points. I’ve come to the conclusion that this should be point-to-point with dual track where necessitated by physical obstacles (cliffs, bridges, etc). Has MRA addressed issues such as this? Chris
Hello Chris,
I certainly like your concept. If you send me a more detailed description of your project, I’d love to help you with some ideas.

Need advice on switching yard layouts for small/narrow spaces that would permit me to perform some reasonable train consist development albeit on a small scale.
Hello JG,
Well, there sure are a lot of examples out there. I would need a lot more particulars before I could help you with that question.
Thanks,

If you look at satellite maps you will see many rail yards. Plenty of great ideas there.
Your double lap oval is another variation of the folded 8.
I don’t know how you plan, but I start with visions in my head of various scenes. I then try to “scale” them in drawings. After all that, then I pick the basic track design that suits my wants – one you don’t have listed is the oval (or its variants) with a branch, and that is what I use. This gives one the option of continuous running and point to point operations. Then I determine which of the scenes I have sketched will fit and try to organize them into a logical plan. Lastly, I understate the amount of space available to allow for errors in the plan and make room for some inevitable changes and improvements. For the group, I, like Steve Doyle, model in scale S.
I am trying to put a second level on my n scale layout and I can’t find the trusess that you have in a pictures on building your railroads there realy for bridges but I can use them for my second story
Hi, Angelo. I would say that the Atlas N scale truss bridges would be a good place to start.
Why do the free videos only last a minute or so and only start on the subject. Eg L gurder video. Only lasts a minute and then won’t allow the next episode to view. This seems to happen often. I can’t afford to pay to watch so only view the free ones. If this is the way it goes then I will be forced to cancel sub. Gerald
Hi, Gerald. Please contact us at 1-855-208-7399; our Customer Service Team would be happy to assist you.
The above is in my mind a must for all new to the hobby and need to learn the railroad jargon. A folded dob bone. Thanks for the info. Al

Just beginning to plan and build an “O” gauge layout.
Modeling G Scale Outside
Advise on what power supply for my 30’ oval track. G scale
I’m in the completing stages of building my L girder for my 13×19’ room layout. It goes all the way around the room with a large “bubble” on each side that allows an additional circumference of 5 more feet of layout space each. I will be using 2” foam for the deck and adding more on top to create mountains and valleys. I have an idea of where I want to place the track, a double mainline and a hidden yard with many sidings and spur lines.
