"Realistic" modeling
Posted by tstage on Wednesday, August 18, 2004 4:40 PM
Be honest. When you're modeling a RR, you're probably tempted to squeeze in every bit of track and operation that you can in your alloted space. (It's NEVER big enough, right?)

Have most of you been able to strike a proper balance between "realism" (how a railroad would look in real life) and making the space or operation "interesting" and enjoyable to operate?

The reason for asking is that a number of layouts that I've seen - EVEN some VERY beautiful and elaborate ones - are sometimes so crammed with "stuff" that they no longer seem very real to me. (How often do you really see 3, 4, or 5 tiers of trains on a mountain side going in that many directions?)

I know, I know. The modeler is attempting to "create" his or her own world and that the confines of space dictate what you can and can not do. You are creating an "effect" rather than "true accuracy". "Realism" realistically has to be displayed more as a "compressed cross-section" of what you would find on a given railroad line.

Okay, given all that: Where do you draw the line? How do you decide what is too much and what is not enough? (Obviously, those of us with smaller layouts would be more likely to fall into this predictament.)

Does anyone else feel the same way? I'm interested in your input.

When I was designing my current layout, I was counseled by David Barrow at the 2000 NMRA convention of the concept that less is more. I am very happy that I listened to him. I have a mainline continuous run (approximately 165 feet wherein the train never passes through the same scene twice. I have had more fun with this layout that some of my previous "spaghetti bowls" which has a lot mnore track per square foot.

Your point is one of the reasons I went from HO to N. Also, I've torn out some track and not laid all I had planned for the same reason. Even so, The Maritime Trunk goes from 0 to 8 1/2 inches elevation by means of a shelf around a room. It just aint natural. It does this moreover in about 64 real feet of mainline run. That's roughly 2 scale miles in N. Unreal as all getout. We just have to live with it and have fun.[:O][(-D]

Ever ride over the Gotthard Pass in Switzerland? Descending the south ramp from the Gotthard tunnel, you can actually see 3 or 4 places where you will be shortly. I tried to find a picture of it on the 'net, but to no avail. It's kinda weird seing a train below you seemingly going in the same direction and having it pass by a few minutes later going the other direction. Try this web page and start scrolling down (about 3/4 of the way). The text is in German. You'll also see the church at Wassen on this page (about halfway down)

On the north slope (southbound direction), the train will pass below Wassen and you can see the church above. Then you go through a spiral tunnel and when you come out, you're heading the other way. If you move to the left side of the car, you can see the church again. Then you go through another spiral tunnel and exit going the original direction, this time passing not far from the church.

Wow! [8)] I'm impressed! The "3, 4, or 5 tiers of trains on a mountain side" would definitely both fit and seem appropriate in this kind of depiction. Not surprsing (and very believable) if you were modeling a Europe RR line.

Outside of Europe though, it would still be the exception rather than the rule. Can you think of anywhere in the US one might find a similar set of lines?

Amazingly enough, there is, although not to the same degree as in Switzerland. The UP (former D&RGW line) eastbound from Provo to Soldier summit will make 3 passes in front of you. It can be seen from US 6. Can't find a modern photo, but here's one from an old postcard. http://ghostdepot.com/rg/images/utah/soliders%20summit%20ascent%203%20train%20osspc.jpg. The passenger train on the lowest level would have just come out from under the overpass where US 6 now crosses the line.

I tend to agree... less is definitely better. That said, there are certain spots where real life imitates models. Especially in Pennsylvania. Check out this shot taken by Dave Kerr.

Being able to use dense track and tight curves is one of the appeals of city modeling, for me--and trolley modeling lets me use even tighter curves and denser track. Personally I try to use plans that only run a train once through each scene, as well as point-to-point plans.

A lot depends on one's area of emphasis. Someone who likes to sit and watch trains run and doesn't care for switching might be more interested in a layout based on several long, unadorned swaths of single track with scenery in the background, while a die-hard operator will doubtless concentrate more on track and less on big open vistas.

One thing to keep in mind is that, having limited space, model railroaders tend to choose the most interesting parts of a real railroad to model--yards, engine service terminals, industries, passenger stations, interchanges and other areas "where the action is"--while excluding the "uninteresting" stretches of straight track that don't offer a lot of interesting modeling opportunities but still eat up a lot of model railroad real estate. Unless your pike is in a *really* long hallway, it can be very difficult to model that horizon-to-horizon strip of lonely mainline in one's living space.

One of the pluses of the growing popularity of bookshelf/around-the-room layouts and multi-level layouts is the increased amount of "edge" these types of plans provide. Unlike the 4x8 sheet of plywood, a shelf layout generally only has one length of mainline running through it--maybe two if it's a "dog-bone" loop.

In terms of realism, I try to use prototype right-of-way plans to get an idea of how the prototype was laid out. Typically, due to space limitations, I have to use *less* track and switches than the prototype did, because I don't have the room!

I agree that most tracks run through remote areas with little to no population. What most people tend to model are populated areas (to varying degrees) perhaps because it allows for diverse modeling. Most layouts I’ve seen use most of their layout space to create towns and cities while compressing the distance between them. Space (lack thereof) seems to be the common limiting factor. Modeling aspirations also play a key role. Some people like operations, others like super detailing, while some go for continuous running (and so on - or a mix of all).

One of the reasons I like N-scale is because of the scenery to track ratio potential. I think that part of capturing the realism of railroads is modeling the long stretches of track that runs through remote unpopulated areas. My current layout is set in a fading rural valley with a handful of old worn structures. It’s not crammed with sidings and spurs – well at least some active and some abandoned spurs. My future “dream” layout will feature long stretches of track running through scenic remote areas. I like seeing long trains run through these areas while enjoying modeling natural scenery. I’m seriously considering hiding my all staging areas so I don’t have to take up layout space modeling a large yard (is that a sacrilege???).

You betcha! I would rather have less track on a layout then a layout crammed with track..[}:)] Even on my favorite type of layout -industrial switching-I keep track realistic and believeable...I do not use the switching puzzle type where it more unrealistic looking nor do I use the time saver which I call a time waster.[}:)][:0] My switching layouts must look like the prototype in design.
Now the few times I had the space for a layout then I always base mine on a branch line or a urban industrial branch..You see that eliminates the possibility of over tracking a layout..

I made myself stick pretty closely to my original Idea, one side of the layout room would be pretty busy, Ship docks, tank farm, engine facility, fishing industry, and more served by the RR.

The other side features only a mine and a sawmill. Between the 2 sides will be "natural" scenery, trees plants etc. I hope the concept of contrast is effective when it's done. The room is 10 x 12, layout is around the walls.

Given the space, I would set up one scenic area with no switching for railfanning and then pack in a lot in the rest of the layout. I have found that after a while, just watching the trains run around on the tracks gets to be the same ole thing.

I've operated on several large home layouts, and have always liked mainline runs with nothing but the main and scenery. Two layouts I've operated on have several sections of track that extend for 1-3 scale miles (in HO, 60 feet per mile) with no switches.

I've always wanted to build a large home layout, and am currently doing so. In terms of large layouts, it's sort of small, "only" being a 12x25 three level layout. I decided on a three level layout design because I wanted as much distance between towns as possible. Each level has two towns on it with passing sidings for 15 car trains. My towns are "only" 25-40 feet apart, but I'm trying to replicate the feel of moving from one major urban area, to it's suburbs, into the country, through small towns, and into a second urban area.

And yes, I'm basing my entire layout on a single prototype area. However, that doesn't mean that I'm slavishly following the trackwork. I regularly mirror image trackwork due to benchwork constraints, have mushed two towns five miles apart into one single town, and have moved a canning factory 30 miles west, just so one of my towns wouldn't be a boring "passing siding and an elevator" (I've already got two of those!) The theme, basic trackwork, scenery and operating sceme are wholly based on the prototype however.

To me, a complex layout has nothing to do with it's overall size, nor with how many miles of track it has on it. A 20 scale mile long layout with nothing but a two track main and ten switches is a whole lot simpler than a 10X14 spaghetti bowl with 103 switches. Guess which one I prefer?

Well I am going to try the ultimate for a change. I just bought a house with a 30' x 60' basement. After closing I am planning to model the PRR main from just south of North Philadelphia station to Shore tower a distance of close to 1.8 miles. I have track drawings from Amtrak and plan to use #14 and 16 turnouts and duplicate the real trackage to the best of my ability. I also plan to make the buildings full size. Its not going to be a 90 day project but it is going to be six tracks wide for most of the layout just like the PRR in that area. I'm already making up crossovers on a bench to save time when I can get to work. Do you have any idea how long one of those is at #14? try 3' but are they ever cool looking.

Sometimes, though, those switching-puzzle layouts are sometimes fairly good representation of dense-track areas where switching between a lot of small industries takes place. I have seen Timesaver-type layouts with industries for most if not all spurs, even if one is a lowly team track or an interchange...

Check this out--a Timesaver would get lost in the maze of track that used to cover the western end of R Street, or Front Street, in Sacramento...and that's only the southwestern corner of downtown! The yards visible here were not division points or classification yards, but rather places to shuffle cars between the myriad of small industries located within a few blocks...the tracks shown also represent three different railroads.

I subscribe to the less is more idea, although I admit that the towns along my 80' main are closer to gether that I would like and I have less countryside that I wish I had. I have avoided the temptation of making the same train pass through a scene twice or to have a decked layout for this reason.

I'm planning to have the two left hand tracks of this timesaver inside a locomotive or car maintenance building. "Time waster" BRAIKIE says, "only if you use it a lot" say I. [:D]


Incidentally, the "ghost tracks" marked in brown between the rear double track (upper level main) and the lower level main are some of the trackage I did not lay that I mentioned on my first post on this topic. The brown track marks in the foreground are the original position for the timesaver spur that now will be with its twin in the maintenance building.

As a modular railroader this discussion offers interesting questions. We have a lot of running space and do shows. The problem? Well, not enough switching and pure operations to suit my taste. Can't wait to build a through passenger terminal and some sidings on existing modules where countryside now exists. For a consolation prize, I do the setup in the staging yards with a good switcher and have lots of hostler fun. When I get bored, I run a passenger train or through freight on the main and let them rip. Balance is almost there, when we finish a few future projects.

I'm in general agreement with the posts here. I try to separate into cities and rural, however "urban sprawl" on my layout is pretty bad in places. It's hard to resist putting in that double track.

For me, the fun is the buildings. I think the old brick buildings are beautiful. The relatively inexpensive DPM et al kits help me create a fairly realistic setting. Using the taller buildings helps make the trains look more realistic.

I will have an opportunity to run some trains. I am putting in two smaller towns which will require traveling 3/4 of the way around the room to reach. Add a cutoff and I can make myself dizzy watching them go around in circles if I want to but my fun is slow speed switching operations.

It's always a conundrum when you get started on a layout. I've got a 24x24' garage layout here in California (the Oldsmobile has been banished to the driveway) and you'd think that I'd have room for it all, long mainline and plenty of yard space. Noooo, because I got carried away about sending the main-line over the Sierra Nevada, and not deciding to use helixes to gain elevation. So now I've got one corner that has tracks stacked like crazy (it looks like Spokane WA, in the days when all four big Northwestern transcontinentals merged in one little narrow valley outside of town), and I'm in the midst of trying to figure out what little scenery tricks I can do to at least make them look semi-realistic. As for that enormous yard--oh, well--
this is HO scale, by the way, if I'd converted to N, I'd be home free. But that doesn't mean I'm going to rip it all out and start over, I'm just going to get creative about camoflauge (is that spelled right?). As to tracks winding down various levels, we've got a couple of instances here on the West Coast--Cuesta Grade out of San Luis Obispo on the old SP Coast Line, and Siskiyou Summit in Oregon on the old SP line there. Mountain hugging isn't just done in Switzerland or Colorado.

I was able to maintain a fairly realistic ratio between track and scenery on my 5' x 12' N-scale layout by building only one town on one end of the layout and a mountain resort on the other end. The 85' of mainline originates in hidden staging with a return loop (a large city out of sight) and runs mostly around the edges of the table with inside loops to the resort and town. My thirst for operations is quenched by locating consists of passenger cars on a siding, turning steam locomotives in the small engine facility and moving other locomotives into position for servicing.

If you want, take a look at my web page. Especially in my case, a picture is worth a thousand words[:)]

The spagetti bowl is definitely a turn off. I operate on a layout once in a while that every train passes through each scene twice - kind of like a huge figure 8 folder over on itself. Even this gets old quick. My eventual layout will incorporate one train through each scene. This will help give the illusion that the train is going somewhere.

What a wonderful and diverse set of posts.

I try to understand first what the modeler's theme, priorities, values, level of skill or knowledge, resources and patience are as I view a layout. There seems to be as many different layouts as there are people! If I get a little annoyed, envious or 'green-eyed,' well then that's my problem and not the model's. Model railroading can present a great opportunity for people to share knowledge and stories.

Some folks are limited to space, get bored easily after achieving their goals, while others are simply trying to have some fun. I just try to meet 'em where they're at and not get too critical.

In terms of the real world, there are some pretty congested places out there that do/did look like 'speghetti bowl' layouts I've seen; Hagerstown MD in the 40's, Philadelphia PA in the 30's (and today), the area under the Westinghouse bridge near Pittsburgh PA, Harpers' Ferry WVa, Cumberland MD in the 40s & 50s, Altoona PA until the 70's and so forth. And I'm only scratching the surface as I'm sure there are dozens of other places throughout the good-ole US of A.

How 'literal' you can be when you're limited to a 4x8 space with stock track, stock #4 or #6 switches is the real challenge and 'Art' in this world of building a model railroad. And that's just the layout; how about the engines, consist makeup, structures, geology and so forth.

I try to go for some of the attributes of the road I'm modeling and use those characteristics to make the layout look and operate in a more realistic fashion; i.e. sidings that are functional to shipping and receiving, making the scene different by running trains in a reverse direction, making up and 'breaking-up' trains, setting out or picking up cars, coal drags, fast freights, local and express passenger trains, etc. Sending a train around a bend or into a tunnel and showing up elsewhere on a layout all adds variety, drama as well as whimsey and credence to a layout's theme and story.

Too realistic or not; 'Beauty is (still) in the eye of the beholder.'

On the other hand, 'Fun is Fun!' [:)]

Never big enough is so true.

Proper balance...I'll let you know if I get there! What I have noticed in the past couple years is that layouts I've seen DO have too much squeezed in to look real. What I'm (trying) to say is that they look "typical" of a model railroad, but not "actual" as one would see on the prototype, IMO.

For many years I never even really noticed this, as you see a layout with track and spurs seemingly everywhere to increase the "play value" of the layout, and that's just how you build a layout. I never even gave it a thought until fairly recently, but lately the saying "less is more" has been nagging at me as I plan my layout to the point where I am seriously considering having fewer, but longer spurs. And fewer but larger structures.

Finding that right balance will be the tricky part...
