Station 4 - Chehelis River

Location.

2nd Division

History. The original location of an existing Schafer Brothers Logging Company spur line ran from Brady to a two track log dump on the Chehelis River.

The alternate history is that when the WWSL acquired soon to be abandoned trackage south of the Chehelis River from the Saganaw Timber Company to entice the American Pulp and Paper Company to build a mill. The WWSL upgraded the spur line to main line status, built a bridge spanning the Smith Canal, and then built a multi-span bridge across the Chehelis River at its shortest width.

Design. 

Chehelis River is a vignette based on three photos of a bridge.

While reading up on bridges I came across a timber bridge that used retired rails for its stringers. It would work well for the bridge over Smith Canal. 

The single track main track continues on an embankment (the ground along the Chehelis River is flood plain / wetlands /slough)



 


 

 

It then crosses the Chehelis River on a bridge made up of two deck girder bridges and a concrete girder bridge …. and then enters Tunnel S1.


 





 

 


Track Diagram

 Roadway

  •  The WWSL mainline is well maintained main line.

Scenery. The module is a 43 inch x 5 foot outside curve at the end of the center peninsula. The scenery will consist of:

  •  An embankment at the end of the Demaine yard than ends at the edge of Smith Canal.
  • A waterway that begins as a narrow stream (canal) and ends as a small river. 
  • A embankment (levee) that is the roadway for the main line between Demaine Yard and the Chehelis River Bridge.
  • A tunnel that is bored thru a ridgeline that acts as a scenic view block. 
In addition, I'd like to include a second track on the embankment not powered by the layout to act as the programming track for the DCC system. (The DCC system is located directly under this module).

 Catenary/ Signaling

Catenary/Signaling. Second Subdivision is non-electrified. 

Assuming trackage rights on the real MILW/UP branch line, it would make sense that there would be an automated system. There was an automated crossing at Preachers Slough for interchange with the Saganaw Timber Company. Using that system, I will install dwarf signals just before the Chehelis River bridge and they will be operated by the Dispatcher.

Structures.

  • 1- 65 foot wood and rail stringer bridge with one wood and one stone abutment.
  • 2 - xx foot deck plate girder bridges with a concrete abutment and two concrete piers
  • 1 - 30 foot concrete beam bridge with a concrete abutment.
  • 1 concrete tunnel portal with wings
