Station 14 - Satsop River

Location. Satsop River Bridge is located on WWSL's 1st Subdivision Mile Post xx.

WWSL 1st Subdivision

Approaching the Satsop River from the south (actual compass heading is west) the single track WWSL mainline runs along a long fill to cross over the river on a 300 ft long bridge made up of four plate girder sections on the east side of the river, and a timber trestle section on the west side. The west end of the bridge leads to the top of a bluff overlooking the west shore.

History.

Originally OPLC main line to Camp 9. The first bridge was a timber trestle that burned in 1929. The second bridge was a two span Howe wood truss bridge that was replaced in 1939 because it was inadequate to the loads.

Vignette. The Satsop River is a vignette. It is a recreation of the Tacoma Eastern bridge at Morton Washington.

Design. The track plan consists of a fill approach on the each bank, four deck plate girder bridges over the river, then a wood trestle reaching the west bank of the river. At both ends of the track plan are the decommissioned wye tracks that once supported logging operations at OPLC Camps 7 and 9.

Track Diagram

Roadway.  Both approach tracks (north and south) will have the remnants (old ties and ballast) of wye turnouts that once serviced OPLC Camps 7 and 9. 

The following bridges, piers and abutments will be required:

• 1 Concrete Abutment
  
• 1 x 90 foot Steel Deck Girder Bridge
• 2 x 65 foot Steel Deck Girder Bridges
• 1 x 90 foot Steel Deck Girder Bridge
• 1 x' 60 Wood Timber Trestle 
• 1 Wood Abutment
• 4 Misc Construction Piers

Scenery. Per photograph.

Section Construction is Completed !

As discussed previously, 16 of my right of way sections were recycled from my previous layout WWSL ver. 2.0. I had to construct  12 new right of way sections. Those sections were:

Division 1

• Schafer Prairie (Helix)
• Camp 1 Section (2)
• Headquarters Section  (1)
• Sawmill Section (2)
• Tunnel 1 Section (1)
• Polson Canyon Section (2)
  
• Satsop River Section (1)
• Basalt Section (2)
• Coal Grove Section (1)
• Reload Section (1)
  

Division Point 

• Brady Section  less the traversing tables (transfer table) (2)
• Montesano Section  (1)
• Demaine Yard Section (2)
  

Division 2

• Chehelis River Section (1)
• Preachers Slough Section (2) 
• North River Section (1)
• Wickwood Section (4)
  

All sections have been upgraded to WWSL ver.3.0 (See Section / Module Design ).

 

 

 

 

 

 

Station 13 - Polson Canyon

Location. Polson Canyon is located on WWSL's 1st Subdivision Mile Post xx.

WWSL 1st Subdivision

Vignette. Polson Canyon is a vignette. It is a recreation of the Milwaukee Road's

Design. I wanted to create a winding main line along the Middle Satsop River similar to the Milwaukee Roads main line thru xxxxx and yyyy, with the Olympic Peninsula terrain rather than the rugged terrain shown in the pictures below. 

The south entrance to the canyon is a wooden tunnel portal with rock shed, similar to the Northern Pacific's West Portal Tunnel #5, Homestake Pass, MT.

The main line is a series of 32 degree curves paralleling the Middle Fork of the Satsop River.
The north entrance to the canyon as it approaches the Satsop River Bridge has two abandoned spurs, originally built to service OPLC Camps 5 and 7.

Track Diagram.

 

Roadway.  Main line is WWSL main line relaxed standard.

• Bridge 1 is a 50 ' thru plate girder bridge
• Bridge 2 is a 65' thru plate girder bridge.
• Bridge 3 is a 60' timber trestle on either side of a 50' deck girder bridge.

The roadbed to Camp 5 is OPLC abandoned. The roadbed to Camp 7 is OPLC ties and dirt roadbed.

Scenery.

• Far scenery is high hillside with secondary forest growth.
• Mid scenery is near vertical basalt cliffs and dirt embankments as appropriate.
• Near scenery is river embankment with post-cutting scrub growth.

Catenary/Signaling. The main line is under wire.

Structures. 

• The south entrance to Polson Canyon will have a wooden tunnel portal with rock shed, similar to the Northern Pacific's West Portal Tunnel #5, Homestake Pass, MT.
• If possible, a slide fence will be along the verticle basalt cliff.
• The north entrance to Polson Canyon may have a MOW scene, TBD.
