Geology, Geography, and the like...

I'm a firm believer that if you want to capture a certain area correctly, you must do research.  As I've progressed in my modeling studies, I've found myself increasingly dependent on maps, charts, and other websites which don't say much about the railroads themselves, but rather thoroughly explain what the terrain looks like, the plants and animals which live in the area, how wind and water shapes the land plus, but less importantly, the geology of the land.  When I mean geology, I'm not talking about statistics, numbers, important points, and research conducted by geology professors who old PhD's. but rather simply what types of rocks are present.

How do all these things relate to the model?  Well, just as there exists prototype information about the railroads, towns and other man made masterpieces; there also exists a vast wealth of information of the land, a sort of natural prototype information is what is needed.  Why you ask, because knowing what the land looks like, what trees grow there, what rocks can be found there, even what animals inhabit the area help a modeler capture the feel and the area being modeled.  Think of it this way, you don't model North Dakota with towering mountains, but you also don't model Washington State with no trees.  This is an extreme example, but my point lies there.

So if I am to capture Colorado, specifically Clear Creek county, I will need to look at the natural features of the area.


  • Terrain in Clear Creek is generally steep mountains made of igneous rock (granite type rock) with some sedimentary in areas.  Valley floors with generally be strewn with large rock debris in all sizes, however some silt will still exist, coming from the annual spring melting.  Moving closer to the continental divide, the rocks become newer, sharper, and have less top soil. 
  •  Near the top of the canyon by Georgetown, clear creek is broken into three tributaries in addition to the creek; clear creek runs southwest before continuing straight west to the divide, the West Fork will continue straight west running parallel to Clear Creek, but to the north, Bard Creek sits in between the two in it's own small valley.
  • Major plant species to be in the area will include various bushes, but evergreen trees (a mix of fir, pine, and spruce with the occasional juniper or cedar) inhabit the steep slopes.  Joining the bushes by the water, small stands of Aspen trees exist.  since aspen roots are interconnected, stands of aspen can start near water, but will ranch up the slopes a ways.  For slopes which face the sun (generally southfacing) the terrain is less populated by trees and more by meadows with flowers in the summer months.
  • Animals aren't really that important for the landscape, but if I were to include some animals in the more wild parts of the layout, black bear cougar, Rocky Mountain Elk, and a bison or two would be my choice.  In addition, squirrel and chipmunk plus raccoon and skunk can make appearances in the towns modeled.  And of course, people are in the town too!
So what I have to model are steep slopes with flowers where there would be sun, and dense forest in the shade or where a lot of water may come through.  If near the creek, boulders with some silt will be in and around the creek, making the perfect habitat for a variety of bushes and shrubs, but Aspen will dominate that area.  Towns are usually near water, so most towns depicted will be only a few feet fro water on the model.  Mines may be all over the slop of the mountain, and so miner's cabins along with the supply stores and the mines themselves will be among the tall stands of evergreen trees and the alpine grasslands near the very top of the canyon.  The bottom of the canyon will generally be a very tight and steep climb, but the top will be more open and leisurely.

Where do I get this information?  To start with, here is a map of the region:

However there is also plenty of other useful information besides just a map:

With these two sources, nearly everything I need to know about the landscape, plants, animals and water are now known and noted on this blog.

Module Work

G scale modules are something not often discussed in the model railroading community, however such a subject is essential when working with a portable layout in such a large scale.  It is true that in smaller scales such as N or HO, one 4X8 or smaller will work perfectly as a display railroad at a train show.  However with G scale, the absolute minimum that could be used for a continuous layout would be 5X8 feet, which often won't fit in anything but a pickup truck with a standard 8' bed.  Not to mention, this sized layout for G scale is incredibly small due to G scale's size.

By studying the module standards in place for various other G scale modular railroads including the Sundance Central and the G-whiz gang, I determined that for this project, two different modules should be built:

The module on the left will be the A module or the straight module. Dimensions of 30" width with an 96" yields 20 square feet of area to work with.  in 1:20.3 scale, I can comfortably have a single mainline and up to two additional tracks to provide for sidings, spurs or for a yard.

The module to the right is the B module or the curve module.  The end plates will be 30" wide to match the straight module ends.  overall maximum dimensions for this module is about 45" wide  and 71" long.

The diagram in the upper right is a cross section showing roughly how the legs and braces will be attached.  I plan to have the legs to have a cross section that looks like angle iron, making the leg stable in both side to side as well as back and forth motion.  with the straight module, I plan to have the legs swing up, and one pair may have casters so that the module is easy to set up and move with one person.  I do have to face facts, at the present moment I'm a one man show, and I couldn't even take my dog to college, so really I've got friends, but no one who is close enough to share this hobby with.  Not saying I'm lonely, but I do have to remember no one is around to help.

The next problem is transport.  These modules will require some sort of cover.  I've seen this idea before, and I know it works to build a cart specially designed to hold modules.  in HO scale, these carts can hold up to 12 modules!  In G scale, there is another problem, each module needs at least a few inches of vertical clearance.  buildings, trees, and land forms over a certain height will have to be removed.  I plan to have one tote for structures, cars, and people with another tote for vegetation for every module.  Thus, each module will have at most 2 totes to accompany that module.

Why this standard?  To start with, this keeps the operation simple and keeps the modules from looking over crowded.  Secondly, totes take up space too.  What I've found with previous modular designs is that when in transport, the modules themselves can be neatly packed, but the totes and additional materials always seem to clutter up the back seat, trunk, trailer, or even the passenger seat!

As for the cart: I've worked out the cross wise dimensions below:

Skinned with 3/8" plywood and framed with 2x2's and 1x2's, this cart will be light, but will still require casters for movement.  Each module will have a unique frame that allows it to slide in the cart like a drawer.  Should the cart tip over or need to be laid on it's side, having modules that can't move around will be much safer.  From bottom of the cart to the top, the interior space will be about 56" tall by a hair over 30" wide.  Exterior dimensions will be 60" by 34".  With three modules being stored in the cart, each module will have a space of 17 vertical inches.  Subtract 3" for the frame and another 4" for the scenery base, each module will have 10" of clearance for permanent fixtures.  To be on the safe side, trees and hills over about 8" will still be packed away. All buildings that required substantial time or money to have on the layout will also be removed for the buildings' safety.

Another cart will be used for curved modules, and differ by first only housing two modules instead of three plus it will be shaped differently to best protect the unique shape of the modules.

I want to do a test run by building 3 straight modules and 2 curved modules which would be cheap to build and a manageable project for a summer.  Two carts are also manageable in the back of a truck, SUV or a trailer.  Main reason for the cart is so that the modules won't need an enclosed trailer, simply keeping out moisture is all that is necessary to ensure that the modules can arrive at their destination in one piece and dry.

What can I expect for scenery? Below is a conceptual track plan:

Photos of Cripple Creek


Cripple Creek Colorado is one of the few places where you can walk through history.  Strewn around are signs of the past, giant hoist towers, solid gold bins
