What's the best number or what's the maximum number of industries that should be or could be to put on a 4 x 8-foot layout.

This pertains to HO scale modelers.  The reason I ask this is....   I think I've overwhelmed my layout by trying to place too many industries on my new section of 4 x 8 or I may have too much track on that same 4 x 8.  I thought this section would be my industrial park, but again I don't seem to have enough space for both the track and industries that the track should be able to support.   I'd show images of my layout but, after looking through Sheldon's layout, I'm too embarrassed to show my behemoth, and it's nowhere near completion.  So I'm scratching my head, (and my kids are of no help) in how to place all of what I envisioned as an industrial park with rail access.

Everyone's thoughts are welcomed, cause at this juncture, I'm hoping I haven't overspent on buildings, scenery and well, one never has enough track, cause I'm always modifying the track.

How many industries you have depends on what industries you want to use. A coal mine will take up alot more room than a small factory but will generate more traffic. The size of the buildings you want to use matters alot. Off hand i'd say you should be able to get at least 6 in that space if you're creative.

It seems counterintuitive, but you can fit more in if you don't use those 18" radius "standard" switches and opt for #4s and #5s instead. In fact, other than making loops of track for train set running, I can;t think of a good reason to use the "standards" at all.

Hey Ralph. The main thing to remember is this hobby is supposed to be fun, stress free and from your imagination. I started out slow, I didn't use a layout panner like a lot of people , I just wanted to create my version of what small town Saskatchewan looked like to me. Saskatchewan is the Canadian province I live in.

My dad was a station agent in a small town of 100 people, we lived in the train station as well. So I got a small town blueprint engraved in my brain. As an adult, I spent 10 years driving around this province going to every small town imaginable. I was a certified Fire Alarm Systems tech. So I would work in all the nursing homes and schools hospitals etc.

After work I would take 20 min or more cruising around the towns looking for old muscle cars etc, at the same time I would enjoy the heritage each town had to offer. Old buildings, grain elevators, seed mills warehouses gas stations. on and on.

So everything I can remember from those old towns, I try to incorporate into my layout. The rule of thumb for me is less is more, it is easier to add to the layout than to take away. I can't tell you how many times over the last 8 years, I have built buildings, and moved them around the layout. I learned never make anything permanent until it is.

My layout is 12 feet x 8 feet x 4 feet, and to be honest, it is still too small. lol

I knew I would have an industrial refinery area, a farmers area, grain elevators seed plant etc. a Main Street, a residential area, and a couple of farms. Just the common everyday things in a small town. I at least had that idea in my brain. Then one day I saw a large graveyard outside a small town, and had to add one of those. Some stuff is planned, and others are a happy accident.

My friend Sid who used to be a member of this site, was my model railroad mentor, he passed away years back. Before he died, he told me that whatever you add to your layout has to make sense, I am modelling between 1955 and 1975 somewhere in that era. I am trying to stay true to that era, at the same time it can be a bit difficult.

Bottom line what you decide to put on your layout is up to you, just make sure it makes sense.

Regards Sheldon.

I remember Sid. He was a great modeler.  What happened to his layoutand his stuff?

PM sent I don't want to hijack this thread.

If the industrial area can be seen from both sides, one option is to use bacground scene buildings that are only an inch or so deep mounted back-to-back. This would give the appearnce of two different industries serving sidings running more or less parallel to each other.

I think the easy quick answer to this question is, the right number of industries on any layout is the kind that allows some room for scenery of any kind around them. That will depend on the kind of industry, of course.

In a few short years, I'm going to be in a situation where all I'll be able to have will be 4 x 8 at best, it will be a big disappointment after having a 50 foot long point to point with four communities on it.  But I've been looking at 4x8 plans for a while and the best ones seem to be the ones that have a passing track on either side, acting as a point A and point B since real railroads deliver people or products from Point A to Point B.  That is, if you want to approach prototypical operation.  After studying umpteen 4x8 plans trying to envision some kind of operation on them, I've come to the conclusion that for my purposes point A needs to be basically an interchange with a main line receiving cars. The other side becomes point B, essentially the end of a branch line.  Then the best you seem to be able to get is two customers at either point.  That is, if scenery means anything to you.  You keep the oval because everyone at some point just feels like mindlessly watching a train run, I am no exception.

It's going to be a big painful downsize.  The best that the layout this size can handle is probably two engines and maybe 10 or 12 cars.

Have you considered a refinement of that basic plan, where the branchline actually branches off the oval and climbs above the mainline to a town? The area under the town could hold a small two track staging yard so you could have an eastbound and a westbound train laying over there. The visible side of the mainline would be the interchange with the branch, with cars spotted there for pickup by the mainline trains. The town area would make a good stub ended terminal, like many shortlines had, and due to its elevation over the mainline you'd get alot more precious space for industries.

Until I see an actual track plan of the Sioux town layout with dimensions, I'll never believe that layout is a 4 x 8.  The perspectives in looking at distance views on that layout are just too long. I am a retired architect with some art training too, and I believe I can speak with some authority about this.  At 8:24 is one of several overall views that cannot possibly be on a 4 x 8 surface.

I hold a very unpopular view of embracing layout concepts with a lot of empty negative space. I want to make it clear that it's just me speaking, but an overcrowded layout like that is not what I would do.  There's no telling how many industries are on that layout but man, I feel claustrophobia setting in just looking at that layout. Not meaning to diminish those who enjoy such a layout, including its builder who certainly is very happy with his layout.

That's a very interesting video (U-tube).  I counted 11, and if you count the passenger station and maintenance yard 13 industries.  There are more industries on this layout, but I only wanted the number that was serviced by the railroad.  I'm not going to critique this layout, although it's definitely detailed.

As for a loop, I am still wanting to keep a main line either around the edge of the layout or maybe make a dog-bone for the main.   In trying to use the number 4, 5, or 6 switches will be challenging if I keep a main in the layout.

The real issue is my imagination, the ideas in my head that, by all accounts, must be limited to the space that the layout can support or space available to me.  When your ideas are larger than the space you have, that's what takes the fun out and/or creates the stress in this hobby.  This is what I'm running into.  I'm not trying to recreate a real place, but I am working to create a realistic imaginary one.   

Quote"...whatever you add to your layout has to make sense."

In that regard, I'm right there, creating that realistic layout.  But my mind wants more, and space to have that "more" stops my creative desires.  I can stay true to the era that have created, it's just that in order to envision that imaginary era I dream of, I need more space.

Quote"...The rule of thumb for me is less is more."

This just boggles my mind.  Makes me think that in order to create space I should move to "N" scale. ...Not happening.  I will definitely give this a lot more thought in the coming days.

Quote...the easy quick answer to this question is, the right number of industries on any layout is the kind that allows some room for scenery of any kind around them."

I wholeheartedly agree, and that scenery needs to have parking for the employees, roads for access of trucks and cars to the industry (this is what you don't see in the U-tube video).  That's one of the main things I like about Sheldon's layout, it has that scenery and access.  I'm not too keen on using buildings as a backdrop.  Mainly because that back edge of the layout I expect to have a main line, and I actually don't have any cut in half or facade buildings.   

Quote"The best that the layout this size can handle is probably two engines and maybe 10 or 12 cars."

My existing 4 x 8 (not the new one in this discussion) can handle 5 engines, and if you add in the museum 7.  I'll have to actually count the number of cars on that section of the 4 x8 since I do have one portion of elevated track (like in the U-tube video) where additional cars could be stored. 

Quote...the branch line actually branches off the oval and climbs above the mainline to a town?"

Coming off the existing 4x8 the track does elevate toward the new section.  I'm considering putting in a Helix but it would not be a circle helix.  More of a mountainous rise going from the first 4x8 then to the new 4x8 that would maybe hold a double deck above the new 4x8 but would be a 2 x 8 ft section.  Trying to place that 2x8 ft section I would prefer not attaching it to the house walls.  This would create some extra space, but the main industry on the 4 x8 would be constrained, I believe.

Quote...keep the oval because everyone at some point just feels like mindlessly watching a train run."

Same here, that's probably why I still want a mainline on this new section of 4x8.  Like my grandma use to say "folks love to watch fish in a fish bowel go round and round." Trains are like fish in a fish bowl.

Downsizing!  I can't imagine what that would be like.  My brain is constantly trying to up-size.  There is one way not to downsize, but I call it "rightsize-sizing", and that is to move from HO to N scale.  You won't lose that virtual acreage.  I myself can't see moving to N scale due to my eyes are not what they use to be.  HO doesn't cause the eye strain.  Lastly, I envy you being able to have a 50 ft long layout, the best I can accommodate is 20 ft.

The only trouble with downsizing for me is that, in HO scale, I have well over 50 locomotives and probably five or 600 freight cars, I lost count a long time ago.  Everything was very carefully curated and chosen to represent between 1935 and 1948, several locomotives have heavy custom detailing that I went to a lot of trouble to get.  Sweeping that much stuff out of the door in one swell foop is pretty much nigh unto impossible.  Plus, I'm very attached to a lot of it since so much of it represents what I saw in my youth.

 Not only that, I'm in line to inherit a large collection from a local guy who is several years older than me wants to leave it to me.  That's probably another 20 diesel locomotives and at least 300 and more freight cars. Plus a bunch of passenger stuff that I'm not interested in. Fortunately, my friend and his business partner run a traveling LHS at Train shows and I believe we can methodically dispose of some of the stuff there, especially the diesels and the passenger equipment.

He has used Atlas Snap Switches and some very sharp flex track curves. That said, I was able to duplicate the track plan in Anyrail with 18 inch radius curves. expanding it to 4 1/2 x 9 allowed the use of Atlas 4s. This railroad could not be built with EZ track in 4x8 because of the difference in geometry between the Atlas and Bachmann switches.

Well, I've seen the plan, and I believe it, seeing is believing.  For those who like a lot of track and a lot of stuff in a small space, this guy has really done it.

Of course everyone does everything differently on their own layout, and if I had that exact track plan, I wouldn't try to crowd that city into it, I would've let the industries be a little more freestanding. But this modeler seems to really like building structures, so more power to him.

A 4 x 8 is a 4 x 8, and that's all that ever will be, but this lemon really got squeezed.

A 4X8 is a 4X8, but not all 4x8s are created equal. If your space is limited, you have to think outside the box. I prefer working on a compact layout like this, rather than around the walls. For one thing I am not a flatlander. I grew up around Appalachian railroading, and prefer winding railroads to long straigntaways. I am, by choice, working on a two deck 5x10 as we speak. I used the expanded area to scale up two smaller track plans I built and enjoyed running. I was able to use 22 and 24 inch curves instead of the 18 inch ones a 4x8 would force me to use. My big Alcos will have a place to stretch their legs, and mountain grades to climb.

To me, the thing that the guy in the video has accomplished is that he's taken the space many so called experts write off, and built a convincing belt line type railroad. These were pretty common in industrialized areas, where their purpose was to gather cars for the nig railroads they connected with. often they were owned by a group of larger railroads, and served as a neutral terminal road that kept the big guys from fighting each other in the streets over the traffic generated.

I don't know how this will reproduce in this form, but this Sanborn map is a view of some long-gone very compact street running switching trackage in my hometown, reminiscent of the 4x8 under discussion. The T&NO comes in from the left. It crosses the vertically running MP several times. The T&NO was in this location at least 20 years before the MP arrived.
