NP Trackage

Here's a diagram of the new NP Laurel MT / CB&Q Scottsbluff NE interchange and staging (which generally refer to as the NP trackage):

The grayish lines are a 12" grid. I've included some dimensions for this area of the layout to give a sense of size.

Minimum radius on the NP trackage is the same as it was on the NJ layout - 36 inches. The rest of the layout will be 30 inches on mainlines, with some industry trackage possibly a bit tighter.

At the top of the diagram, where the 3'-0" dimension is, is the doorway that leads into the layout. The dotted lines are the edges of the benchwork. I've adopted a 3'-0" minimum aisleway width for the entire layout.

The Laurel interchange yard is actually somewhat larger than the original I built in the NJ version of the layout - there are now three yard tracks rather than two, and the tracks are longer than they were. The engine servicing area will also sport a larger roundhouse than I had room for before.

As you can see in the diagram, there is room for some industry tracks near the engine terminal area inside the turnback curve, and possibly in the area behind the tracks at the opposite end of the yard. Time will tell whether or not I utilize these areas. I may increase the size of the engine servicing facilities (adding a second track to the turntable, for example, and a rip track).

Towards the bottom of the diagram you can see where the tracks penetrate the wall into another room at the bottom. This room will hold the Seattle and Minneapolis stanging yards, which have been combined into one six-track yard with a through track in the center. One side will be used for Minneapolis (or eastbound) and the other for Seattle (westbound).

Sometime in the next couple of weeks I'll post the basic arrangement for the Wyoming mianline and the Cody branch.

A Status Update...

Layout planning is continuing. A workable general arrangement of benchwork and major layout features has been developed, and only (only!) detailed planning is left to be done.

This version of the layout will be simpler than the New Jersey version that was under construction, for a couple of reasons:
  • First, I want something I have a chance of completing to a major extent (all trackage, basic scenery, and detailed scenery in some places) within a decade or so. I want to have most of the main tracks operational and be able to start ops sessions within a couple of years.
  • Second, while I have about the same square footage available as before, the configuration is different, and I have also to make allowances for access to areas around the layout that are not train related (storage closets, spare bedrooms, media room, etc.).
  • Finally, and maybe most importantly, I don't just want to undertake a project of such megalithic proportions again - at least right now.
Yeah, I know purely text posts aren't as interesting as photos. As soon as I have the track planning a bit farther along, I'll post some of the in-work diagrams.

The Phoenix Begins To Rise!


Work has just begun on the newest incarnation of the CB&Q in Wyoming! Just barely - the first section of benchwork has just been started. But the important thing is that it has started!

Track planning is probably about 20% complete and is ongoing, but one part of the layout has been firmed up enough to begin construction.

Photos and the in-progress track plan will be posted soon, so check back!
