After giving my layout a lot of thought, (in my job I have ample time to over-think anything) I have decided that the best thing to do will be toma. I have also decided that I will model in N scale using ntrak standards. I have therefore thrown out the idea of using the plan I was considering and instead just letting the layout grow. One of the biggest problems I was having was narrowing down what to model. I decided that with ntrak modules I can simply  build a module of whatever I have the fancy to model at the time. Next time I'm home it's off to the lumber store to get the materials for my first module.

Sounds great...

Sounds like a good plan, I am doing the same in free mo HO. The one suggestion I would make would be to try and pick a time, place, and era so your modules are cohesive and you avoid buying anything that strikes your fancy. Say a 50 mile stretch of track that includes a variety of what you like. For example, I have two modules in progress, one is a mid-western town centered around a depot and elevator, the second is a single to double track module next to a pond. Both are specific aspects of the prototype that I really wanted on the layout but are separated by several miles. By keeping my modules in the same geographic area, they are more cohesive together, especially for ops.

TOMA

I'm also trying the TOMA concept, except in HO. My layout will be total freelance, modeling somewhere in Arizona 1954 - 1969 running the SP and Santa Fe. I have the track down on my first module and I'm hoping to get the wiring finished soon.  It'd be nice to see my NW2 running around on it!

Cohesive modules

I'm not so much worried about cohesive modules as I am interesting scenic elements sanchomurphy. Each module will be it's little section of the world. I'm not as much of an ops guys as a builder I think. That may change in time but when that time comes I'll just rebuild modules to meet that need. I'll have some permanent modules such as a yard and a roundhouse as I like those elements and they are useful to any module. That's great Steve, I really had a hard time choosing between HO and N. I have done both in the past and was leaning to going back to HO due to product availability, but landed back on N simply because it is easier to get better looking curves and fit more into a small module area.

What is TOMA?

You all talk of TOMA...aside of Top of the mind Awareness, I find nothing.

TOMA = The One Module Approach

TOMA = The One Module Approach

Basically, the idea is to do a home layout as a single module section at a time, building the module to completion before getting too involved in the rest of the layout.

You add a 1x12 with some staging tracks on each end and run some trains back and forth through the finished module.

This way it becomes weeks or months instead of years to a finished, operational layout.

One module not enough to suit you? Then great, build another, move out the staging tracks, and now run trains on TWO finished layout sections.

TOMA is intended to get you experiencing the full scope of the hobby much faster (design to ops) and allows managing layout scope in small bite-sized chunks instead of embarking on a basement filling monster and the huge investment in time and money that requires.

We all like to buy locomotives and rolling stock as we go instead of pay for it all up front. Yes, it's less efficient that way, but it's a lot more fun - and a hobby is first about FUN.

Why not do a layout that way too - build it to completion as you go? That's TOMA.

P.S. TrainMasters TV is doing a new series on building a TOMA project layout - read about it here. We're titling the series: Start small. THINK BIG.

Hi Hikermike,

If you use the MRH search facility at the top right of the the screen, these 2 links should help to explain things

N trak a TOMA?

Since N trak has been a module concept that you build to completion since the 1980's is it really a TOMA or it just an N trak module?

A bit splitting hairs

but N trak can be a form of TOMA, just like any other modular standard, depending on your approach.  Some just build two or three or four N traks to join up with others, or their club, not to have a layout, but if you build a layout out of N trak, isn't that a TOMA?

The whole point of this is that the building process will be documented and presented in 2017 on TMTV and MRH, so that's where you'll find it soon enough.

We used Model Railroad Benchwork's modular benchwork kits to build our benchwork for this project railroad. To do this series we defined our modeler who was building this layout in advance and one assumption we made is he's living in an apartment complex and doesn't have access to a shop. The only saw he has is a saber saw. So the premade modular benchwork is perfect for our hypothetical modeler on this project.

Model Railroad Benchwork is an MRH Marketplace advertiser, so to learn more, visit this link.

When each monthly episode airs, you will be able to "rent it" for a week and watch it for $1.49 each. If you can't afford that, you're in the wrong hobby (wink) ... there will be 10 episodes in all, or 14.90 total. Once it's done, it will also go up on the MRH Store for sale to own, which will be next fall.

I'll also be talking more about some TOMA experiments I've been doing starting in the January 2017 issue of MRH.

N-Track vs. TOMA

The One Module Approach (TOMA) can certainly be built with standard interfaces such as required by N-Track but needn't since it is your layout and not necessary to connect with any other modules.

If you feel the urge to interconnect with others in HO or N then consider looking at FREMO or similar groups in other scales. This allows free-form "modules" that have a standard interface at the ends but no requirement as to size or shape. It also encourages a single track mainline with passing sidings as FREMO was developed to allow operations for those who may not have enough space for a large layout. In fact, some of the setups can get quite huge when groups from several regions get together. There was one set up in Portland that had me thinking of building just one to bring to other shows and try a new scale (like I need more hobbies!).

The TOMA as suggested by the publisher, Joe, is intended to get people out of the chair and to build something. This can be a single track or many to gain experience and confidence with bench work, roadbed, track laying, building switches (if that appeals to you), scenery, bridges and buildings, and control systems. One module can take as long as you want or, if you feel the urge to run trains, the staging area suggested at either end (or one connected around the room for example) will allow some operations. 

At any point a new module can be added as part of a "grand plan" or to explore new ideas. Some have suggested that once the track is down, move on. Others may want to completely finish the 4', 6', 7', or whatever before trying another. Again, these needn't be complicated and, imho, the first should be kept simple. One track, a station, or a bridge or industry could get you involved for some time. Once you find what appeals to you then the next may be better and the first becomes a "chainsaw" that will eventually be removed or replaced.

The systems available for building bench work as in the TMTV video make some of the work for those with little room or confidence an avenue to build a section with less fuss and muss. Systems also exist for roadbed or "homo-bed" style that are ready to lay and designed for track and switches to go right down. This is a hobby that can allow you to explore many avenues. Some may take you down the rabbit hole into Wonderland. Electronics has done that for me and re-kindled my interest in trains in whole new ways. Enjoy!

    Hey Joe, I have a question regarding this approach to a building a layout.
   
    The main inquiry that I have is, can the TOMA method be used to build a medium/small room-sized layout that has been planned out prior to starting construction? You see, the layout that I am planning is built around a 5'x 9' core (itself being an inherited pre-built 4'x 8' table with a 1'x 5' and 1'x 9' extensions on either side. That will be my starting point. It's basically a modified Cactus Valley RR trackplan with a loop, grades, and some spurs and sidings for some operation.
    The rest of the layout is going to built in sections when I get the urge to expand (similar to TOMA?) so that if I have to move the layout to a different location, all the sections are already separate from each other.
   
    Otherwise, I had intended to build the railroad in stages (i.e. first benchwork, then track, then wiring, ad infinitum), though building it one piece at a time is an interesting way to go about it.
 
By the way, here is my Cactus Valley mod in case you wanted to comment on it.

I'm not Joe, but Jon, I think the answer is yes. From what I've seen, the TOMA approach lends itself to linear layouts, but there's no reason why a continuous layout couldn't be built one piece at a time.
 
Keep in mind though that TOMA is one of several similar concepts that involve expanding a layout over time.  Building an initial central layout then building outwards is not a new concept and has its own advantages over building modules one or two at a time. For instance, a lot of people prefer running their trains on a circuit. TOMA will get a person there eventually, but if only building one or two sections at a time then running in a loop becomes the final achievement, not the first.

TOMA can take many different configurations.
 
The original idea with TOMA was a way to get armchair modelers past the fear of starting a layout by keeping the scope small ... and to make it easy to do a chainsaw project (a project you can learn on and throw out when you're ready to move up to something more challenging). Originally it was called the "One module challenge" and looked like this:
 
TOMA-01.jpg
 
The idea is build something easy, then make it operational by adding temp staging on each end. Then run some trains! If you would like more layout, then build a second module section and expand the layout, and so on.
 
But all along the way, the scope remains manageable, and if you ever change your mind as to your layout, then you can replace a module with something else. Generally, prefer the max module size to be no more than 6 feet long and 2 feet wide. Anything larger gets difficult to maneuver through halls or around corners inside a house.
 
There's nothing that says you have to connect the two module sections together directly. Here's some other scenarios that give you some quick temp running space between towns -- we call this TOMA with a twist:
 
TOMA-02.jpg
 
There's nothing that says you can't add some temp continuous running connections and add double-ended staging for even more flexibility:
 
TOMA-03.jpg
 
There's also nothing that says these temp connections can't be simple module sections that are scenicked. You can even scenic the staging if you wish. One note, the corner module sections are deliberately made smaller (no more than 4 feet) because we've found 6-foot corner modules become very awkward to maneuver through halls and around corners inside a house.
 
TOMA-with-a-twist-2b.png
 
You can also connect two module sections like this below to get continuous running (although you do give up staging):
 
TOMA-05.jpg
 
We also feel TOMA can take a cue from the good ol' 4x8 but use module sections to allow easy further expansion later:
 
TOMA-06.jpg
 
A slightly larger footprint makes for a bit more module real estate like so:
 
TOMA-07.jpg
 
So there you have it. Hopefully you can take the basic TOMA concept and just let your imagination run with it.

    Joe, thank you for the kind explanation of the concept of TOMA. I really like all the possibilities for configuration.
 
    To be honest, the urge to have a functional layout has grown to be quite strong recently, with the primary inhibiting factor being lack of permanent space, and so, I have elected to build a 4'x 8' without any grades (all the faster to build with, my friend), with a loop, and also some spurs and sidings for switching should I get tired of seeing the train chase its tail. 
    The trackplan will be either the Alkali Central or the Soo Line Red Wing Division, both from Model Railroader. I like these because, in addition to a loop and some switching, they both utilize a scenic divider that makes them appear to be larger than they really are.
   The layout would have casters on one end so as to be stood on that end and rolled into a storage room.
   
    That being said, I had envisioned extending my little layout by using modules which, coincidentally, closely (I think) matched the TOMA concept, to allow for some longer linear runs across the floor, something which intrigued me since I connected some lengths of flextrack, added power, and ran trains back and forth down that stretch a few months ago. In that scenario, the 4'x 8' would serve for the most part to provide continuous running.
     
    Overall, TOMA is a unique concept and is one worth thinking about.
 
    I will close this post out with a joke, if you don't mind.
    Here it is:
