Introduction to the wide variety of layouts possible
From LdsigWiki
You have a model railroad and you want to tell a friend about it. What do you say? How do you describe it?
You probably start with scale. That tells what size the trains
are. You might mention a railroad name, a geographic location,
or an era. This gives a little more information about what you
might see on the layout, but it doesn't describe the layout
itself.
The layout type or style is analagous to a home style. A realtor
mentions a ranch, tudor, bungalow, colonial, Queen Anne or
California contemporary, and we have a better idea of what the
house looks like. We don't have any idea about the furniture
inside, but we have an idea of the house itself.
The type and style of a model railroad layout can refer to the
general track arrangement and operating pattern of the layout and
the form and construction of the layout benchwork. Some layout
types seem to go with particular layout styles and vice versa,
and a layout can have a combination of styles. As eyes glaze
over, I can only say that everything will become as clear as mud.
Let's start with layout types. Some are described by the
layout's general operation. For instance, a switching layout
concentrates on industrial spurs and terminal trackage where
trains are broken down and the individual cars are delivered to
industries for loading and unloading or interchanged with another
railroad. Mainline running of trains between cities is not
modeled to any great extent or is simulated by staging.
A trolley layout would consist of electric railcars running
through downtown streets and into the suburbs with frequent
service and short trains.
A branchline layout might model a lightly travelled line as it
leaves the mainline and ends at some small town or industry.
Only one short train may be running at any time. The mainline
connection might be simulated in the manner of a switching
layout.
Other layout types are described by the track plan. A point to
point layout consists of two towns or terminals and the trackage
between them. Trackage at either end point might be simulated
with staging. A branchline layout could be a point to point
layout.
A variation of a point to point layout is a point to loop. The
second end point is replaced with a reversing loop. A train
returning to its starting point after traveling the length of the
railroad is presumed to be a different train. Another variation
is to increase the size of the end loop to the maximum possible
and reduce the connecting mainline to a minimum creating an out
and back layout. In this, the loop is the mainline. Replacing
both end points with reversing loops creates a loop to loop
layout. A town between the two loops could be the focal point of
the layout. In any of these configurations, the end reversing
loops might contain staging tracks.
Then there are track plans that are basically circles or ovals of
track that are bent, twisted, squashed and smooshed into
different shapes. Give one end of an oval a twist and you have a
figure eight. Fold in half and you have a twice-around. Or go
around three times. Followed to an extreme, with tracks running
everywhere, you get the spaghetti-bowl layout.
Go back to the oval. Squish the middle together and you have a
dogbone. Bend the dogbone in the middle and you have a folded
dogbone. Bend the ends of the dogbone in a "C" shape and you
have the waterwings. The dogbone can be bent into any number of
shapes.
Or should I say, any "letter" of shapes? The waterwings is a
"C". You can also shape it into E, F, G, H, I, J, K, L, M, N, O,
P, S, T, U, V, W, X, Y, and Z. Doubtless, it could be shaped to
represent the other letters, also. A point-to-point layout could
be bent into these shapes just as easily.
But now we are talking about the overall shape of the benchwork.
This could be considered as the layout's style. One that most
people start with is an island. That oval of track on a sheet of
plywood is an island layout. You can set it in the middle of the
room and view it from all sides.
As it grows to be a larger island, you might add an access hatch
in the middle so you can crawl under the layout and pop up to do
maintenance on areas you can't reach from the outside. This
opens up some new viewing angles that you like, so you enlarge
the access hole and then move the controls in to make an
operating pit. The layout is now a doughnut.
After a while, your knees get tired from crawling in each time
you want to run trains. You give yourself direct access to the
operating pit. You now have a walk-in layout.
But only the visitors can wander around and get all the good
views. You're stuck on your stool at the control panel. You put
your throttle on the end of a long cord and move the controls to
a number of smaller panels near the things they control.
Eureka!! The walk-around layout.
The layout is still in the middle of the room, with an aisle all
around. You discover you walk farther than the train travels, so
you switch things around. Give the aisle space to the layout and
the layout space to the operators. You've created an around the
walls layout.
If we allow the layout to extend across the doorway, we create an
access problem similar to that of the doughnut. You have to get
into the room somehow. Bending all the way over at the waist to
get under the layout, this type of access is called a duck-under.
Over time, it is called far worse names. These names depend on
the length and overhead clearance of the obstruction and the
height, age and physical grace of the individual forced to
utilize such access. But if we raise the layout in the area
blocking access to chest height or better, it becomes a
nod-under. If we raise it high enough, it becomes a walk-under.
Or we can cheat, and create a lift out section of benchwork to
gain access. This, too, will come to be called other names
depending on the elegance of the construction, the ease with
which it is used, and the consequences of failing to replace it
properly. Or we can avoid the situation entirely by combining
features of the walk-in layout with the around the wall layout.
We still have a lot of floor space in the middle of the room. Not being into square dancing, you give some space back to the layout. A small bump soon extends across the room, leaving only aisle space between it and the rest of the layout on the far side. It's a peninsula. (DANGER! Peninsulas can grow and multiply to occupy all available space.)
At some point, we run out of floor space, though we still desire
more layout space. Your spouse glares at you as you measure the
dining room. Retreating to the layout room, you realize the
solution has been there all along, above the layout. A SECOND
LEVEL!
Welcome to the double deck layout. This utilizes the air space
above the first level. As you walk around the layout, you will
have two scenes in front of you, one above the other. You use
the same aisle space, but the layout itself has double in size.
If double decking is still not enough, you don't have to stop at
two levels. Go for three. Or more.
A variation of a double deck layout is the mushroom layout. This
places two levels such that they are visible from different sides
of the benchwork, eliminating the visual confusion of two scenes
in view at once.
Our around the walls layout can be contained in a more family
friendly version known as a bookshelf layout. As the name
implies, the depth is about that of a shelf. A bookshelf layout
can continue around the room just like the around the walls
layout and can become a multi-level layout, also.
Then there are special considerations that come into play in
layout design. If you might have to move, there are ways to take
your layout along. A sectional layout can be built such that it
can be broken down, moved and reassembled in the same
configuration. How often you expect to move the layout will
affect the construction details of how the sections join
together.
A modular layout is built in segments with standardized track
locations and wiring at the ends of each segment. These can be
combined in different arrangements. Modules built to the same
standards can be combined into larger layouts by clubs locally or
even on a national level, dwarfing even the largest home layout.
Intimidated by all of this? Then take the opposite approach and
build a tiny layout. Some are able to fit in a brief case.
Others resemble a tiered wedding cake in their size. These can
be little jewels by being able to concentrate on such a small
area.
Remember that a layout is not limited to just one style. There is
much overlap in the previous descriptions. There is no
inherently right or wrong style. Create and innovate. Combine
elements that suit your purpose. Use what will help you get the
layout you want.
