Section 12 - Tunnel 1 - Part 2

In the last blog (Section 12 - Tunnel 1 - Part 1) I identified the layout design elements of the Tunnel 1 Section and laid out the roadway lines. 

In this blog I am identifying the scenery construction concept and laying out the landforms.

Scenery Design Considerations

Background.

Sky, Clouds. There is 1 backdrop 22 inches in height. It will be a simple backdrops- a clear blue sky suggesting a sunny day. 

Landforms  

Ridge. The terrain at the North Portal will be consistent with the Polson Canyon ridge line. There is a more moderate slope along the east face of the ridge. 

Here is the generic photograph of the southern part of Polson Canyon as it approaches the the North Portal of Tunnel 1.  

On this section, I continued the construction of the Polson Canyon ridge line with the 2 inch styrofoam. The ridge should be at least 3x the height of the train to provide a reason for the curvature of the main line thru the river valley. Using 2 inch styrofoam insulation, this would make the rock faces at least 7 inches high with the maximum height of 11 inches for the ridge at the rear of the section.  Additional height of the ridge can be painted on the backdrop.  See 5.5.6 Mountains and 5.5.5 Rock Faces for construction details.

Saddle

The tunnel is sited through an enlarged saddle with basalt rock walls on both sides. The possibility of rock spalling due to steam engine smoke stack exhaust requires timber tunnel lining. No additional engineering is required within the tunnel area. 

Tunnel Portal The terrain at South Portal will be a basalt cliff face with a concrete portal. I will use 3/4 inch styrofoam and hydrocal plaster to model the rock shelves and will use matte medium and modge podge for the waterfalls and creek. See xxxxxxx for construction details.

Embankment. An embankment with a dry creek bed comes down the moderate hillside to the eastern river riverbank. Again, I have selectively compressed the AREA standard 60 degree angle to 45 degrees from the edge of the roadbed to the river bottom. This allows a greater river bank edge along the fascia. See 5.5.3 Embankments for construction details.

Waterways

Creek.

Several streams and dry creekbeds will drain from the ridge line toward the river meandering along the the fascia.

Once the basic land form as completed, it will be covered with Sculptamold on the flats and hydrocal plaster on the slopes. Flat areas will have some degree of undulation will be covered with sculptamold. 

Ground Cover

1. Far ground cover on hills and ridges will be modeled with teased and dyed felt. See for construction details.

Near ground cover along the right of way will be a variety of dead, summer and early fall grass colors.

Vegetation

The hill and ridge land forms will maintain a denser growth of second growth conifers, dead trees, stumps and bushes, indications of previous logging activities 

The embankments will have a heavy growth of shrubs and bushes, with growth along at the river's edge. See 5.7.1 Shrubs

Section 12 - Tunnel 1 - Part 1

Its time to layout the Section 12 - Tunnel 1 section. The layout design given and druthers of this section is identified in Station 12 - Tunnel 1.

 Design Elements

Tunnel 1 is the lower reach of the Polson Canyon river valley. The right of way tunnels through the ridge line paralleling the Satsop River and approaches the Olympic Peninsula Logging Company sawmill.

This Section consist of one section and consists of  layout design elements (from geographic north to south):

1. A single track main line from Polson Canyon to Sawmill.
2. A single track tunnel. 
   
3. An abandoned OPLC logging line crossing the WWSL main line.
   
4. A turnout off the WWSL main line to the OPLC main line and industry complex.
5. A 90 foot turntable owned by the OPLC in support of the Sawmill operations.

Section Construction

This section is a turnback curve portion of the WWSL layout. It is approximately 5 foot wide by 42 inches in depth (restriction due to lolly post).  It follows standard section construction, except it has three 1x3 girders The two ends of the section are cut out to permit attachment of the module electrical connectors and section interface bolts. See the WWSL section construction reference page for the construction technique.

ROW Design Considerations 

The most critical design considerations on this section is curvature of the main line. The turnback curve section width is 60 inches. Technical specification is a minimum 4 inches between track and the edge of the fascia. This restricts the turnback curve to 48 inches (24 inch radius).

Because this section ties into both the Section 11 - Sawmill and the Section 13 - Polson Canyon, some layout of those sections will need to be done at the same time, primarily the main line locator at the southern-most Polson Canyon curve (6 inches from the fascia ) and the WWSL and OPLC main lines at Sawmill  (4.5 inches from the fascia).

2. Curved track within a tunnel is generally rare, but not unheard of, in the prototype. It is more common in railroad modeling layout design. The location of the tunnel and the restrictive view minimizes the suggestion of a curve within the tunnel. 

I have located the main line at the tunnel entrance 7 inches from the fascia. This allows me to model some portion of the ridge on the outermost side of the tunnel complex. It also allows for removal of part of the fascia to access the tunnel for cleaning and (god forbid!) re-railing errant rolling stock. I'm thinking clear plastic/lexane so that visitors can see the prototype engineering and construction technique used in building the tunnel. This allows 10 inches clearance at the Tunnel 1 - Polson Canyon and Tunnel 1 - Sawmill connections for turnout placement.

Laying out Right of Way

I am not going to go into great detail about putting down the roadbed lines. See the Right of Way Reference Page  for the details if you haven't had the fun to do it before. 

Essentially you're going to follow this process: 

1. Lay out the main line curves. It is a simple 24 inch turnback curve.
   
2. Lay out the tunnel template.
3. Lay out the north and south tunnel portals. 
4. Layout the northern switch to the OPLC main line and sawmill complex. 
5. Layout the turntable approach track from the sawmill yard and spurs.
6. Generally locate the turntable location. 

Laying out the Turnout

A turnout is required to connect the WWSL main line with the OPLC main line, arrival/departure track, yard lead track and and industrial spurs.

Laying the track.  Tunnel 1 Roadway is WWSL Medium Profile Roadway. See 4.2.11.2  Modeling Technique for Medium Profile Roadway for details. See 4.2.3 Laying Straight Track and 4.2.4 Laying Curve Track for construction details.

Laying out the Structures 

Tunnel 1. There are three parts to a tunnel, the tunnel portal, the tunnel bore, and the tunnel lining. See 4.1.10 Tunnels for basic tunnel engineering information.

North Portal

North Portal

The North Portal will be a re-creation of the Homestake Pass MT, west portal, NP Tunnel #5. It has a timber portal and a rock slide shed I will represent the latter with a timber tunnel lining and a timber rock shed that extends from the portal. 

 

See 4.1.10.1a Tunnel N1 North Portal for construction details. 

 

See 4.1.10.1b Tunnel N1 Rock Shed for construction details.

 

Tunnel Bore

The tunnel differs slightly from the traditional tunnel in that it has an additional height due to the electrified zone. The drainage profile will differ as well. The fascia will be removable to allow viewing of the interior. See 4.1.10.1b Tunnel N1 Tunnel Liner for construction details.

Southern Portal  

South Portal

The south tunnel entrance will be a re-creation of the April 2002 Mainline Modeler cover photo.  

The rock wall will be constructed with vertical 1 and 2 inch styrofoam insulation with a rock casting overlay.

I will represent the latter with a concrete portal. See See 4.1.10.1a Tunnel N1 South Portal for construction details.

MOW. There will be a section tool house and tunnel inspection car pull off.

Turntable

TBD

 In the next blog (Section 12 - Tunnel 1 - Part 2) I will discuss the Landform Design Considerations.

 

Section 13 - Polson Canyon - Part 2

In the last blog (Section 13 - Polson Canyon Section - Part 1) I identified the layout design elements of the Polson Canyon Section and laid out the roadway lines.

In this blog I am identifying the Scenic Design Considerations. Polson Canyon is a river valley. The right of way parallels a ridge line on the east side and the Satsop River on the west side. 

North Canyon

Center Canyon

South Canyon

As a refresher, here are the scenic elements:

1. A spur off of the ridge line with a sparse growth of second growth conifers, dead trees, stumps and bushes. An abandoned OPLC right of way at the left (north) end of the module - formerly OPLC Camp 7.
2. A ravine steeply rising to the background with series of rock shelves making a waterfall scene.
   
3. An abandoned spur - formerly OPLC Camp 5, curving along the ravine.
   
4. A curved river valley with moderately steep hillsides and rock faces. with a sparse growth of second growth conifers, dead trees, stumps and bushes. 
5. An embankment with several streams and draws coming down the steep hillside and embankment to the river.
6. A heavy growth of shrubs and bushes at the river's edge. 
7. A river's edge along the fascia.

Scenery Design Considerations

Background.

Sky, Clouds. The backdrop available for the Polson Canyon section is 22 inches in height. To the north, it will be a continuation of the rain clouds on the Satsop River section. The remainder of the Polson River section will be a simple backdrop - a clear blue sky suggesting a sunny day. 

Landforms  

Hillside

The north end of Polson Canyon will be a hillside that has been partially excavated to permit the Camp 7 spur off of the ridge line with a sparse growth of second growth conifers, dead trees, stumps and bushes. See 5.4.6 Closer Hills for construction details. 

Ravine

The ravine steeply rising to the background with series of rock shelves making a waterfall scene. It needs to tie into the closer hill land form to the north, and the steep hillside and rock faces of the Polson Canyon, while providing an acceptable right of way to the abandoned spur to Camp 5.

I internet searched a number of ravines/creeks, but what really interested me is a ravine scene created by Woodland Scenic and was on the back cover of a modeling magazine. Land form wise it supports all the elements in the previous paragraph when selectively compressed. 

Ridge

Polson Canyon's predominant land form is a curved river valley with moderately steep hillsides and rock faces. 

The ridge should be at least 3x the height of the train to provide a reason for the curvature of the main line thru the river valley. Using 2 inch styrofoam insulation, this would make the rock faces at least 7 inches high with the maximum height of 11 inches for the ridge at the rear of the section.  Additional height of the ridge can be painted on the backdrop.  See 5.5.6 Mountains and 5.5.5 Rock Faces for construction details.

Rock Faces. Here is the generic rock face along the main line as it approaches

Embankment. An embankment with several streams and draws coming down the steep hillside and embankment to the eastern river riverbank. For my purposes, I have selectively compressed the AREA standard 60 degree angle to 45 degrees from the edge of the roadbed to the river bottom. This allows a greater river bank edge along the fascia. See 5.5.3 Embankments for construction details.

Waterways

Creek. I will use 3/4 inch styrofoam and hydrocal plaster to model the rock shelves and will use matte medium and modge podge for the waterfalls and creek. See 5.8.3.1 Creeks for construction details. 

Several streams and dry creekbeds will drain from the ridge line toward the river meandering along the the fascia. 

The Satsop River, initially modeled on the Satsop River section, continues it southward run toward the Chehelis River at Montesano. It runs parallel to the main line in Polson Canyon along the fascia. The river will be approximately centered on the module and will disappear to the left and right front as the result of the curvature of the main line. As in the Satsop River Section, the river bottom is to be gravel with larger rock strewn among the waterway and the bank. The river depth will be shallow or, in some locations, merely wet dirt.  See 5.8.4.2 Rivers for construction details.

Once the basic land form as completed, it will be covered with Sculptamold on the flats and hydrocal plaster on the slopes. Flat areas will have some degree of undulation will be covered with sculptamold. 

Ground Cover

1. Far ground cover on hills and ridges will be modeled with teased and dyed felt. See for construction details.

Near ground cover along the right of way will be a variety of dead, summer and early fall grass colors.

Vegetation

The hill and ridge land forms will maintain a sparse growth of second growth conifers, dead trees, stumps and bushes, indications of previous logging activities 

The embankments will have a heavy growth of shrubs and bushes, with growth along at the river's edge. See 5.7.1 Shrubs

Section 13 - Polson Canyon - Part 1

Its time to layout the Polson Canyon section. The layout design given and druthers of this section is identified in Station 13 Polson Canyon.

North Canyon

Center Canyon

South Canyon

Layout Design Elements

The Polson Canyon section adjoins the Satsop River section to the north and the Tunnel 1 section to the south. 

Polson Canyon is a curved river valley with moderately steep hillsides and rock faces, with a sparse growth of second growth conifers, dead trees, stumps and bushes. The right of way parallels a ridge line on the east side and the Satsop River on the west side (fascia) through a series of cosmetic 32 degree (26 inch) curves.

The Polson Canyon section consist of two separate sections (16 foot long total) and consists of two geographic areas: North, and South Canyon (from geographic north to south):

1. A spur off of the ridgeline with a sparse growth of second growth conivers, dead trees, stumps and bushes. An abandoned OPLC right of way at the left (north) end of the module - formerly OPLC Camp 7.
2. A ravine steeply rising to the background with series of rock shelves making a waterfall scene.
3. Two 4 bent timber frame trestles with wood abutments.
4. One 10 panel plate girder bridge
5. An abandoned spur - formerly OPLC Camp 5, curving along the ravine.
   
6. A curved river valley with moderately steep hillsides and rock faces. with a sparse growth of second growth conifers, dead trees, stumps and bushes. 
7. One through plate girder bridge.
8. One beam bridge.  
9. An embankment with several streams and draws coming down the steep hillside and embankment to the river.
10. A heavy growth of shrubs and bushes at the river's edge. 
11. A river's edge along the fascia.

Section Construction

See the WWSL section construction reference page for the construction technique. 

As this section has a river module I have modified the construction technique. Instead of using the two 1x3 girders on the bottom of the section, I need a solid bottom on the module for the riverbed. The 1x3 girders are replaced by a 2 foot by 8 foot piece of plywood 3/4 inches thick. The two ends of the section are cut out to permit attachment of the module electrical connectors and section interface bolts. 

The remainder of the section is built per standard WWSL construction standards.

ROW Design Considerations 

The most critical design considerations on this section is the curvature of the main line track. These curves are 32 degree (26 inch) cosmetic curves. The width of the roadway in the river canyon must be approximately 8 inches in order to have 8 inches of hillside and 8 inches of river scenic elements. The number of curves must fit three less than 180 degree curves (with easements and tangents) within the 16 foot sections.

1. Camp 7 abandoned right of way.  See 4.2.11.13  Modeling Technique for Removed Roadbed for Camp 7.

3. I pulled up a construction diagram of a timber trestle built by the Union Pacific.  That diagram has each bent a distance of 15 feet apart. In HO scale that's a bit less than 2 inches per bent. Five bents and a wood abutment is about 10 inches. See 4.1.9.4 Polson Canyon Bridge N4 for construction details.

4. The steel plate girder bridge is an Atlas bridge with 11 panels. Total length of those two trestle and one steel plate girder bridge will be about 29 inches. See 4.1.9.4 Polson Canyon Bridge N4 for construction details.

5. Camp 5 abandoned right of way. See 4.2.11.12  Modeling Technique for Dismantled Roadbed for Camp 5.

7/8. There will be two additional bridges in Polson Canyon. Based on the shallow nature of the stream and draw, one bridge will be a 50 foot through plate girder design. See 4.1.9.3 Polson Canyon Bridge N3) and the other bridge will be a 20 foot beam design (See 4.1.9.2 Polson Canyon Bridge N2).

Putting down the roadbed lines 

I am not going to go into great detail about putting down the roadbed lines. See the Right of Way Reference Page  for the details if you haven't had the fun to do it before. Several things to note for this section:

1. I need to layout the curve from the Satsop River section first.
2. I need to layout the curve from the Tunnel 1 section second.
3. I work the curves from each end to the center of the Polson Canyon sections. See the curve template development section below for how to do it.
   
4. I can adjust the locations of the curves with track tangents in the center of the two inner (concave) curves  and/or the center of the two outer (convex) curves.
5. The Polson Canyon bridges are centered on the curve tangents. Bridges N2 and N3 are on tangents with no additional calculations needed other than abutment placing. Bridge N4's plate girder bridge length must be determined in advanced so as to properly place the point of curvature for the northern-most curve. 
6. Locate the abutments and piers (to include heights).
   

Cosmetic reverse curves

Looking at the photo above, a model railroader would probably call the track layout an S-curve. Calling this section of roadway an S-curve isn't really prototypically accurate. The railroads see this as a series of curves and engineers them appropriately. 

In model railroad layout design there are actually five functional curve types and one cosmetic curve type. This photo actually is called a series of cosmetic reverse curves. See 0.4.5 Curves for additional details.

The WWSL sometimes uses easements on its main line right of way. I am modeling a Cosmetic Reverse Curve for the NMRA Master Model Railroad Certification Program. You may choose to eliminate the easement in each reverse curve to simplify right of way construction. In this section there are 23 elements in the roadway construction:

1. easement  - simple curve  - easement  - Bridge N4 (tangent)  
2. easement  - simple curve - easement - North tangent   -
3. easement  - simple curve  - easement - Bridge N3  (tangent)
4. easement  - simple curve - easement - Rock wall   (tangent)
5. easement  - simple curve - easement - Bridge N2   (tangent)
6. easement  - simple curve x2  - Tunnel 1 (the left half of a turnback curve)

See 4.2.4.4 Laying out a Cosmetic Reverse Curve for additional information.

Laying the track.  Tunnel 1 Roadway is WWSL Medium Profile Roadway. See 4.2.11.2  Modeling Technique for Medium Profile Roadway for details. See 4.2.3 Straight Track and 4.2.4 Curves for construction details.

Laying out the Structures 

There are no major structures on this section. The Camp 7 right of way has an auxillary water tower located along the main line.

In the next blog (Section 13 - Polson Canyon - Part 2) I will discuss the Scenery Design Considerations.

 

Section 14 - Satsop River Bridge - Part 2

In the last blog (Section 14 - Satsop River Bridge - Part 1) I identified the layout design elements of the Satsop River Bridge Module and laid out the roadway lines. 

In this blog I am identifying the scenery construction concept and laying out the landforms.

As a refresher, here are the scenery elements:

1. A darkened cloudy sky suggesting inclement weather is approaching. 
2. A mid distant tree line and visible riverbank.
3. A shallow river with significant sand and gravel on the river bottom and sides.
4. A sloped bank on the north side of the river.
5. An embankment on the south side of the river.
   

Scenery Design Considerations

Background. The backdrop available for the Satsop River Bridge Section is 22 inches in height. With the bridge height at approximately 4 inches, and the roadway centered at 12 inches on the module, a 45 degree angle would suggest that the background trees painted on the backdrop could be 8 to 12 inches in height. This would then allow 10 inches of cloud/sky. Rainclouds would cover about 5 inches of this cloud sky space.

Once the bridges were build and temporarily placed I can shape the river and the river banks, adding foam as necessary to reach the bridge abutments. 

Mid-ground.

The river will be approximately centered on the module and will disappear to the right rear. The base of the river will be the 3/4" plywood base. The river bank will be a slow rise to the left and a fill embankment to the right, and a background land mass. 

Background land mass.  My initial plan was to use only extruded polystyrene insulation but realized that should I have to move the section, the mid-distant land mass would break loose. I have chosen instead to use a 1/8 " luan panel to anchor the landmass. The panel is sized to the height of the riverbank on both sides (approximately 4 inches) and about 6 foot long.. It is anchored to the benchwork with L shaped anchors. The riverbank will be 1/2 inch thick polystyrene . This is a good height for the edge of the distant river bank, and an additional two and half inches in height three inches deep from the backdrop will give sufficient base for a line of trees and shrubs adding depth to the backdrop painted trees, and several inches of depth to plant the trees without them falling over. See 5.5.7 Three Dimensional Backgrounds for construction details.

North river bank. The north river bank (left) is a natural occurring slope. I found a picture of the timber trestle bridge being used by the Mount Rainier Scenic Railroad. The slope is essentially flat for quite a distance. I will selectively compress the distance and create a greater slope. The 2 inch polystyrene is cut at about a 20 degree angle to model the slope with the base reflecting the effects of erosion caused by the occasional high river in spring. Building the trestle in advance is indicated in order to locate and cut in.the north abutment, and locate and place the trestle piles. 

South river bank.  The south river bank (right) is a man-made embankment. The AREA standard for an embankment is a 60 degree angle from the edge of the roadbed to the river bottom. I'm cheating a little bit by cutting the foam terrain on the backside of the embankment to a sharper slope while the visible side is AREA standard. See 4.1.1.2 Embankments for construction details. Using to total length of the bridge complex, I will locate the south abutment and cut it in. Pieces of polystyrene and expanding foam will complete the basic land form.

Foreground

This section's foreground is the Satsop River. The river bottom is to be gravel strewn. I have two gravel sources: 1) an unknown brand of gray kitty litter, and  2) a bag of Quikcrete general purpose paver mix. I am not sure yet what product will be ultimately used, probably both - the kitty litter for the water covered gravel bottom, the paver mix for the dry rock shoreline.

The critical piece of river construction will be the location of the bridge piers. A wood footprint of each pier type will be constructed and temporarily screwed into the section base from below. 

The water product is also undetermined. I have not poured a river yet, and am not sure whether epoxy, decoupage resin, or a Woodland Scenics product will be right for the river. It all depends on how the gravel bottom looks (dark and wet enough to pass as gravel).  The river's edge is a continuation of that product at double to triple thickness (depending on the distance from the river's edge. 

Because this is a wide shallow waterway, I am using stream construction techniques. See Streams for construction details.

Section 14 - Satsop River Bridge - Part 1

Its time to layout the Satsop River section. The layout design given and druthers of this section is indentified in Station 14 Satsop River.

Layout Design Elements

The Satsop River section adjoins the Basalt Sand and Gravel section to the north and the Polson Canyon section to the south. This section has of eight layout design elements: (from backdrop to fascia):

1. A darkened cloudy sky suggesting inclement weather is approaching. 
2. A mid distant tree line and visible riverbank.
3. A shallow river with significant sand and gravel on the river bottom and sides.
4. A 5 bent wood trestle and a wood abutment. 
5. Two 16 panel plate girder bridges
6. Two 10 panel plate girder bridges
7. 4 unique piers 
8. A concrete abutment for one of the 16 panel bridges.

Section Construction

See the WWSL section construction reference page for the construction technique. 

As this section is a river scene I have modified the construction technique. Instead of using the two 1x3 girders on the bottom of the section, I need a solid bottom on the section for the riverbed. The 1x3 girders are replaced by a 2 foot by 8 foot piece of plywood 3/4 inches thick. The two ends of the section are cut out to permit attachment of the section electrical connectors and section interface bolts. 

 The remainder of the section is built per WWSL construction standards.

ROW Design Considerations 

The most critical design considerations on this section is the length of the bridge. With only 96 inches of linear space to model two curved legs, two river banks and and 5 bridges, something has to be compressed. 

First I looked at the two curved legs. At Basalt, the 26 inch radius curve needs to connect to a tangent track located 10 inches from the front fascia. That means that 16 inches of space is needed on this section for the north wye design element. At Polson Canyon, the 26 inch radius curve needs to connect to a tangent track located 16 inches from the front fascia. This means that 10 inches of space is needed on this section for the south main line and the abandoned spur track. A total of approximately 26 inches is needed for the curved main line components. That leaves us with 70 inches of tangent mainline track for the five bridges. See Satsop River Bridge N5 for the baseline construction details.

4. I pulled up a construction diagram of a timber trestle built by the Southern Pacific.  That diagram has each bent a distance of 15 feet apart. In HO scale that's a bit less than 2 inches per bent. Five bents and a wood abutment is about 10 inches. See Satsop River Bridge N5 (Timber Pile Trestle) and Satsop River Bridge N5 (Wood Bulkhead) for construction details.

5. I am planning to kitbatch the plate girder bridges. I have eight Atlas Thru Plate Girder Bridges, six of them have 10 identically spaced steel plates, the other two have 10 steel plates of different widths. I chose to use two of the 10 panel bridges to represent the 16 panel bridges. This is a 38% selective  compression of the bridge scene. All I need to do is shorten the height of the two bridges by approximately 1/3rd. Total length of those two bridges will be 18 inches.

6. Using the selective compression percentage above, I will need to add (rounded up) 4 panels to each of the two 10 panel bridges to represent the 20 (modeled 14) paneled panel plate girder bridges. Total length of those two bridges will be 25 inches. 

See Satsop River Bridge N5 (Deck Plate Girder Bridge) for construction details.

7. There are 4 interesting piers to be constructed. Three are wood pile bents, one is a steel pile bent. They will have to be kitbatched.See Satsop River Bridge N5 (Steel Pier) and Satsop River Bridge N5 (Pile Piers 2-4)  for construction details.

8. The concrete abutment will have to be designed to reflect the dimensions of the embankment constructed. See Satsop River Bridge N5 (Concrete Abutment) for construction details.

Adding all those bridge lengths gets me to about 53 (18+25+10) inches, with a leeway of about 17 inches for 'off the bridge tangent track' leading into the curves at each end.

Laying out Right of Way

I am not going to go into great detail about putting down the roadbed lines. See the Right of Way Reference Page  for the details if you haven't had the fun to do it before. 

Essentially you're going to follow this process: 

1. Lay out the main line. I centered it at the 12 inch line.
   
2. Lay out the transition template line.
   
3. Lay out the main line curves. 
   
4. Lay out the bridge template, the length of the bridge and adjust as necessary.
5. Lay out the south embankment leading to the bridges. 
6. Locate the abutments and piers (to include heights).
7. Layout the sloped river bank on the north side of the river.
   

Because this section ties into both the Section 15 - Basalt and the Section 13 - Polson Canyon, some layout of those sections will need to be done at the same time, primarily the main line locator at Basalt (10 inches from the fascia) and the northernmost Polson Canyon curve (16 inches from the fascia ).  .

Laying the track.  The 1st (North) Division is WWSL Medium Profile Roadway. See 4.2.11.2  Modeling Technique for Medium Profile Roadway for details. 

See 4.2.3 Laying Straight Track and 4.2.4 Laying Curve Track for construction details.

Laying out the Structures 

There are no major structures on this section. There is a section maintainers tool shed, bridge tie pile and a rail car shed for a bridge inspection car.

In the next blog (Section 14 - Satsop River Bridge Module - Part 2) I will discuss the Scenery Design Considerations.
