Choosing Model Railroad Track Configurations

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.

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.

    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

    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

    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.

    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.

    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.

    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.

    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.

    About to dismantle/reconfigure my layout, but it’s always good to start with “basic training”!

    I’m starting a new build in ho, just figuring out what I want to do in the garage, my space is 14 X10.
