Station 12 - Tunnel 1

Location.

WWSL 1st Subdivision
Tunnel 1 is located on WWSL's 1st Subdivision Mile Post xx.

History. The idea of a logging railroad having tunnels seems remote but there have been good reasons for loggers to build tunnels. The Olympic Peninsula had three operational logging tunnels.

  • Clemons Logging Company had a tunnel in the vicinity of Melbourne. It was built in 1922-23. [1]
  • The Port Angeles and Western (originally Olympic Spruce Railroad #1) had two tunnels - the Daley-Rankin bore and the 46 foot McFee bore built in 1917-1918. They were operational for 36 years.  [2]

Design. Tunnel 1 has two functions. First (South Portal) it is the end point of the Station 11 (OPLC) module and contains a 90 foot turntable in support of the Sawmill operations. Second (North Portal) it is the start point for the Station (13) Polson Canyon Module.

Roadway.  

  • WWSL main line will be WWSL relaxed standard. 
  • WWSL tunnel will be WWSL main line standard and will have a rerailing fixture at both entrances. 

Scenery.

South Portal

The south tunnel entrance will be a re-creation of the April 2002 Mainline Modeler cover photo.The backdrop will be medium blue sky. The far scenery will be the basalt rock formation shown on the cover. The mid and near scenery will be level ground.

The tunnel itself will be a wood paneled tunnel lining upgraded in 1953 with a concrete portal and gunnite lining. The fascia will be removable to allow viewing of the interior.

 

 

North Portal

The North Portal will be a re-creation of the Homestake Pass MT, west portal, NP Tunnel #5. [3]

 The backdrop will be medium blue sky. The far scenery will be a basalt rock formation. The mid scenery will be a mountainous terrain dropping to track level. The near terrain will be a cut to river level.

 

 

Catenary / Signal. 

  • (C)  The main line will be wired. The turntable and the approach track will not be wired.


Rolling Stock.

Maintenance of way operations will require a hopper car with an icicle removal frame. If there is room, a tunnel maintenance inspection car could be added.

Modular vs Sectional Design

Modeling Information

There are two types of layouts, movable and immovable. Having been in the military for 14 years and moved some 8 times in those 14 years, I opted for a movable type of layout. I've moved it three times in the next 20 years as a civilian. 

There are two types of movable layouts: modular and sectional.

Modular Type A. By definition,  a module is a section of benchwork and roadbed that is built to  common standard determined by the organization establishing the standard. Modules fit together with standard track connections at the ends, but builders can construct any kind of scene on a given module. - as long as one module fits against another module railwise. Modelers are generally confined to fixed-length modules of 4, 6, or 8 feet long.

Ntrak is one of the modeling organizations that has created a commond standard and other modeling groups have developed standards of their own. Those layouts you see at train shows and flea markets are modular type A layouts.

Modular Type B. Another group that does modular but differently is Fre-mo. Free-mo was developed with the idea that allows the modeler’s creativity to shine through their modules.  The Free-mo standard focuses mainly on the module endplates. The Free-mo mainline is centered on a two foot end so modules can be inverted 180 degrees and still mate up to the adjacent module without modification to wiring or track. This allows modeling of prototype trackplans and operations in a modular environment. The length and track configuration of a Free-mo module or module set is up to the modeler as long as the module endplate standard is followed. .

Sectional. Sectional design assumes that the layout is going to be moved at some point. Unlike modules, the sectional layout does not follow any standard track pattern because the pieces need to fit together only one way. The scenery can maintain continuity from section to section following the theme of your railroad.

Benchwork is the same, the only difference is the connection points are designed with a move in mind. Assuming you don’t have to take your show on the road very often, you don’t even have to leave breaks in the track and scenery at section joints. When it’s time to move, simply cut the rails and slice through the terrain. As long as you have some extra track and scenery materials on hand, you’ll be able to “heal” the scars at the section joints

Dominos. David Barrow devised a sectional construction system using standardized rectangular layout segments (think table layout that disassembles). He likes to lay out track plans by fitting these sections together end to end and forming 90-degree corners, so the comparison to the game of dominoes was obvious. He’s  described his domino method in both Model Railroader and Model Railroad Planning articles. The illustration shows the basic form of domino layout sections.

The WWSL

WWSL ver. 2.0 was several concepts wrapped up in one. I wanted modular construction that would be easy to move . I was taken with the idea presented by David Barrows about 'domino's. His choices for his layout was:

  • Segmental benchwork construction.
  • Minimalist design aesthetics rather than a realistic scenicked railroad.
  • Wide aisles.
  • Finished open room with carpeted floor.
  • Off-the-shelf unpainted code 100 flextrack and no. 6 turnouts oeperatied by manual ground throws to minimize wiring and complexity.

This made alot of sense to me - after all all my layouts to date had essentially been minimalist designs rather than realistic scenicked railroads. Heck, I hadn't even painted the plywood green!

This minimalist idea was followed by Tony Koesters Layout Design Elements That allowed me the opportunity to develop a model railroad focused on operations with an ability to change the layout based on my change of operational preferences. I always enjoyed switching, and car movement, mainline operations as shown in the model railroading magazines of the time less so. I did enjoy the freedom to build a multi-track coal mine with empty and load yards, and then months later change those LDEs to reflect a grain elevator and its similar but also unique requirements. Wetting down the white glue'd down flex track and reconfiguring the industial spurs was a way of continuing the hobby as I enjoyed it. 

The WWSL vers. 2.0 domino. While David Barrow's dominos used plywood as its subroadbed/roadbed, I knew at some point I would decide to do a WWSL vers 2.0 which would entail scenery, etc.  Mounting a plywood base directly on the bench work gives you ZERO opportunity to work in any downward verticle scenery. I saw styrofoam and the 2" x 2s as a way of allowing the vers 2.0 the option of having some features such as roadbed slopes, small streams, culverts, bridges, etc. 

The requirements of the military move didn't support the idea of L-girder benchwork, so my modules were constructed so that when it came time to move all i needed to do was disassemble them into the core 2 foot x 8 foot sections and then surround them with 1/4 inch plywood to avoid the enevitable move damage.

The section was essentially a two inch piece of styrofoam glued to a 1/8th inch of masonite with wood  glue. A twenty four inch 2" x 2" piece of lumber was screwed and glued into the masonite panel and was then screwed onto an L-girder made up of a 1"x 2" and 1" x 4" lumber. 2" x 2" legs were bolted to the L-girder ala Lynn Wescott.

In this case, the styrofoam, the masonite, the 2" x 2"s and the 1"x3" gives approximately 4 inches of downward dropping scenery potential. 

The WWSL vers.3.0

The WWSL vers. 2.0 was single decked for a number of years. I found that the second level was difficult if not impossible to install with the L-girder in place. When I started the benchwork for WWSL vers 3.0 I removed the Lgirders and installed a horizontal 1"x3" in its place - to add vertical stiffening to the section. This is what the vers 3 module looks like. 

I'm recycling 16 WWSL 2.0 sections to the new version. I've found those sections much easier to built, carry and install on the layout.

Station 11 - Olympic Peninsula Lumber Company

 Location.

WWSL 1st Subdivision

OPLC (SM) is the fourth station on WWSL's 1st Subdivision. located at Mile Post xx.

History. See Olympic Peninsula Logging Company.
https://modelingthewwsl.blogspot.com/p/112-olympic-peninsula-lumber-company.html

Operations. 

This module is the location of the Olympic Peninsula Logging Company's sawmill operations. That operation consists of: a 5 acre millpond, a sawmill, a chipping mill, 4 dry kilns, a planing mill, and a locomotive servicing area and turntable.

See Mill Operations. http://modelingthewwsl.blogspot.com/p/oplc_12.html, for additional information.

The OPLC operates its own railroad 5 days per week and moves 30 carloads a day. from two reload locations to the sawmill millpond. The even numbered reloads are accessed thru Camp 1's southern main line, the odd numbered reloads are accessed by trackage rights on the WWSL main line north of OPLC. A yard switcher operates at the sawmill location. 

See Railroad Operations, http://modelingthewwsl.blogspot.com/p/oplc-railroad-operations.html, for additional information.


Design Considerations.
I wanted this module to show a 1950's logging and sawmill activity. Specifically I wanted to show:
  • Log train transferring logs from cutting locations to the millpond.
  • Production activities from millpond to sawmill to drying sheds,  kiln and planning mill.
  • Loading activities of rough and finished lumber.
  • Chipping operations.

The OPLC railroad operations consists of a one track arrival/departure yard, a one track yard lead that services a two track millpond, a one track sawmill, a one track chipping mill, a one track timber dock and rough lumber loading track, a one track planing mill. There is a locomotive servicing area and turntable.The OPLC has a main line running parallel to the WWSL main line from OPLC to Camp 1.

Track Diagram
 
 

OPLC is spread out over three modules. The millpond, sawmill and chipping mill are located on module 1, dry kiln, rough lumber loading, the planning mill and finished lumber loading is on module 2 and the turntable operation is on module 3.

Roadway.
  • OPLC Main Line is relaxed standard..
  • OPLC Yard is relaxed standard.
  • WWSL Main Line relaxed standard.

Catenary/Signaling. WWSL main line will be wired. OPLC main line will not be wired. 

Scenery.
  • Backdrop will be low hills with 2nd growth trees .
  • Dry kilns will be backdrop flat.
  • Middle ground will be industrial dirt.
  • Near areas will be flat dirt ground with miscellaneous vegetation.
