SALMON CREEK TO PRYOR TERRAIN

Moving down from Montieth Rock (https://espeecascades.blogspot.com/2018/09/montieth-rock-and-tunnel-21.html), I filled in terrain the rest of the way to Oakridge, including the mainline crossing of Salmon Creek.  I use the "Pryor" name for this area, as that is un-modeled siding located between Oakridge and McCredie Springs.  Ironically, I originally planned to begin my terrain forming efforts here.  Instead, this major stretch of landscape became one of my last.  The tunnels and trestles of this past year simply "commanded" my attention.  

This relatively simple stretch of terrain went swiftly.  I installed the pink foam slabs and then covered the surface with Sculptamold in about a week of work.  Most of this terrain was my basic sloping hillside, formed by slabs of Styrofoam at my desired angle.  That angle is steeper than most natural ground.  Consider that artistic license to compress the scene within the available depth.


Pink Styrofoam panels installed for the terrain leading down to Salmon Creek in the distance to the left.

I filled in terrain around the mainline bridge crossing Salmon Creek. The foreground terrain awaits bridge construction for the Pope and Talbot lumber mill spur.  Filling in around the mainline bridge allowed the terrain to fill in against the back drop continuously through this area.  I used vertical slabs of Styrofoam for the creek area terrain, as that more easily allowed me to form my desired terrain.


Terrain forming for the mainline bridge crossing Salmon Creek.

I created a small hill on the RR-East side of the creek and then got carried away with terrain forming against the backdrop.  I carried that hill too far into the Oakridge scene. Overnight, I wrestled with this and concluded a change was in order.  I needed to open up the RR-West end of Oakridge more to fit the real scene and, critically, to provide space for Oakridge's Beech Street and the signals at that end of Oakridge.  Quick work with a putty knife and a carving knife removed the offending terrain.  I then formed a new end to the hillside and cleaned up the backdrop.  I patched the basic backdrop paint after the Sculptamold was applied.

Excess hillside against backdrop has been removed and the hill reformed.  A ramp for Beech Street has been formed to ensure I do not forget about this feature!

With terrain formed, I applied Sculptamold.  Most of this used my tan earth color, though some areas, especially around Salmon Creek, received a gray paint filler.  I exhausted my supply of Sculptamold with about six square feet of hillside left to cover.  I had placed an order for more last week, right after the Montieth rock exercise. This order arrived the next day after my major Sculptamold effort.  I immediately returned to complete the scene and take pictures before my regular Tuesday night railroad operating group met.  I also was able to cover additional terrain I had formed in the Salmon Creek area.

Finally, it was time to run a train through the freshly completed scene.

I have just a couple of major patches of terrain yet to go.  The missing areas require some other activity before I work on them.  One of those is Cascade Summit, immediately above the just-completed scene from Salmon Creek to Montieth Rock and McCredie Springs.  Evident from the photos here, the open areas for the rear part of the summit scene overhead provide open light paths right now.  Lighting for the "land down under" is one of those "other activities" that must precede terrain work for Cascade Summit.  Meanwhile, my crews can enjoy their trains rolling through more completed terrain.

MONTIETH ROCK AND TUNNEL 21

My scenery efforts have moved around to my "land down under"--the area between Oakridge and McCredie Springs underneath the upper layer and Cascade Summit.  Specifically, I have covered at long last Tunnel 21, just before McCredie Springs.  I also tackled my significant sculpting exercise--Montieth Rock (also known as "Rooster Rock" but not to be confused with a similar formation in the Columbia River Gorge).  The rock formation over the RR-East end of Tunnel 21 also needed sculpting, as both formations basically are volcanic basalt plugs. Inspiration photos can be found in books, as both rock formations dramatically frame the railroad action below them.  Once again, Joel Ashcroft's excellent SP Cascades website can be consulted:
http://spcascades.railfan.net/  Specifically, the photo section for Pryor to McCredie Springs has a view of the RR-East face of Tunnel 21 and a couple of views of Montieth ("Rooster") Rock:

I began terrain construction in this area by establishing a foundation. A scrap piece of hardboard was supported by scrap pieces of plywood to provide a level platform for Styrofoam for the terrain.  For Montieth Rock, I cut slabs of three-inch thick Styrofoam, roughly sixteen inches square. These just fit between the roadbed and the wall.  I created a stack of five primary slabs and then cut two more smaller pieces that would form the top "crown" of the rock formation.  Referring to photos, I drew outer rough outlines for each slab. Given the undercut at lower heights of the rock formation, this often meant keeping track of the extreme width needed for each slab.  I cut to these lines using my bandsaw.


Rough outline for Montieth Rock formation.

Studying photos, I began carving the rough form to shape, slab by slab. My photo study revealed an outcropping on the RR-West side (the side showing in the photo above).  I needed to keep that extension while cutting back the main part of the rock.  I also discovered a second spire behind the main crown.  This showed in photos from the steam era, available from the Oakridge Museum.  I found I worked best by carving the foam in several iterations over the course of several days, refining the cuts as I went.  Lacking photos of the RR-East (geographic west) face of the rock, I used my own judgement based on similar basalt plug formations.  I kept it simple.  Most photos of Montieth Rock are shot from the area of Tunnel 21 as that is both the most accessible to enterprising photographers and provides both track level and elevated perspectives.


Montieth Rock sculpted and shaped--ready for its Sculptamold covering.

Turning to the nearby Tunnel 21, it too has a shear rock face on the RR-East side.  I built up this terrain using slabs of Styrofoam oriented whatever way made the most sense to me.  Along the tunnel portals, these were one-inch thick pieces arranged vertically.  Above the tunnel and its liner, I used more of the three-inch thick slabs.  Above this, was a bit more using both a vertical one-inch piece and a wedge cut from a three-inch slab.


RR-East portal of Tunnel 21 with the rock face above it roughed in. Note the many wires behind and above the Styrofoam formation.  The hardboard channel to their left will form a conduit for additional wires for the signal system.

An important consideration for the corner rounded by Tunnel 21 is its use for routing various wires to Cascade Summit overhead.  This currently includes both the DCC power and a 12 volt DC supply for switch machines.  I anticipate adding a dedicated booster for Cascade Summit, so I needed to add cables for the NCE cab bus, a grounding wire, and a power cord.  I also added a paired wire set for planned LED lighting under the upper deck.  Finally, I provided a separate "conduit" (slab-sided channel) for the cabling needed for the planned CTC and signal system. 

As I built up the terrain forms around the room corner and above Tunnel 21, I realized I should cover those wires and the slab conduit a bit. I cut a fairing from a styrene "For Sale" sign (a good source for a sheet of plastic).  I installed this around the wires and slab conduit using adhesive caulk and flat-headed brads.  We shall see how this survives over time.  Meanwhile, I will need to add a bit of spackle over the brads and then paint the fairing.

The RR-West side of Tunnel 21 needed a gentler slope, though it also had what will become rock faces.  This side of the tunnel extends to terrain behind McCredie Springs.  I used my standard terrain technique for locations like this where I first place a back panel against the wall/backdrop and a front base with slope.  I then filled in most of the space between these two panels with appropriate length pieces cut from four-inch wide slabs of one-inch thick Styrofoam.  The hillside slopes down to the room corner, behind the rock bunker I will locate here.  The lowest portions of the hill were filled in by Styrofoam strips, cut and sloped as needed.


RR-West end of Tunnel 21.  The hillside and rock above the tunnel blend to a hillside behind McCredie Springs, off to the right.


Gaps between Styrofoam slabs have been filled with spray foam insulation. All of the foam has been carved and shaped and is ready for a Sculptamold covering.

Finally, it was time to cover all of the shaped foam work with Sculptamold. My initial plan was to do this in two stages--the primary rock areas and then the hillsides.  In the end, I used that sequence, but spent a long afternoon doing all of the Sculptamold.  I mixed fairly stiff batches of Sculptamold for the rock work.  The vertical faces and even an undercut on Montieth Rock needed that stiff mixture to adhere to the Styrofoam base.  I usually add my gray base paint to the Sculptamold mix for rock work.  Pictures showed the rock faces to be darker and a bit warmer than my base gray, so i added burnt and raw umber to the gray paint and Sculptamold mix.  I probably needed an even darker paint base, but I at least have the rock faces showing a bit differently than the surrounding terrain. The hillsides gradually blend from my gray base toward my tan base away from the rock formations.

Working in this "land down under," I recognize I need to deal with the lighting for this area soon.  I plan to install LED lighting.  I have been waiting for this technology to mature, which it largely has, but the need for it is very evident today!  Meanwhile, I have fleshed out another signature geological feature for my railroad.

BELOW CRUZATTE

My terrain forming efforts finally turned to filling in the gap alongside Cruzatte.  Below Cruzatte are my Tunnel 20 and the RR-East end of Wicopee.  With my narrow shelf construction around the walls, the terrain slope must be steep.  While I might have spread the distance between the lower line, including Wicopee, I chose to keep the layout space narrow for easier access to Cruzatte and to provide for wider operator aisles.  I hope to conceal some of this with trees, but for now, the base terrain emphasizes the height difference between the two lines.

Terrain construction followed my now-familiar pattern of establishing top and bottom bases for sloping Styrofoam slabs.  I tried to provide a few bump-outs and outcroppings to break up the otherwise flat slabs.  I also was able to angle a few of the slabs and indent them to break up the surfaces.


Terrain base between Cruzatte above and RR-East Wicopee below.  

Several special requirements were catered to during the construction. First, I finally needed to build up abutments and then fill around Cascade Creek.  Cascade Creek is spanned by a pair of deck girder bridges toward the RR-East end of Cruzatte.  A waterfall is on the uphill side of the railroad.  I needed both the uphill waterfall and another one on the downhill side. The lower waterfall needed to "flow" into a creek that I chose to route along the tracks to join Noisy Creek. All of this eventually becomes Salt Creek on my railroad.  Consider this the compromise necessary with selective compression of the real geography to fit into a basement layout space.


Cascade Creek formed with waterfalls on both sides of the tracks.

Another terrain issue was providing access hatches.  One of these was the second hatch covering the footpad for access to the deep part of the Shady Creek scene.  I used three-inch thick Strofoam to help form the opposing terrain forms for this hatch.  I then formed long terrain slabs from Tunnel 8 above down to the base near the lower track below, attaching them with caulk to both of the three-inch terrain formers. Finally, I used a saw to cut the top shell slabs, using the slight gap between the formers to guide the saw.


Cutting the upper end of the hatch covering the footpad for Shady Creek access.  Tunnel 8 at the RR-West end of Cruzatte is above.  The lower track connects McCredie Springs to Wicopee.

I also needed to provide hatches for access to future signal locations. Four signal assemblies will be installed at Cruzatte--two at each end.  Most of these hatches were simple affairs of two 4-inch wide Styrofoam slabs glued together with a reinforcing slab and propped between the lower base and the plywood subroadbed for Cruzatte.  One of the hatches needed to be wider to account for a support arm for the Cruzatte roadbed.  The exact signal location may fall on either side of this support, so I used a 16-inch wide Styrofoam slab for this hatch.  Each hatch has some sort of extra formation to break up the otherwise flat slab.


RR-East Cruzatte signal access hatches removed.

After filling gaps and adding to the slab formation with spray insulating foam, I carved and shaped the terrain slabs.  Finally, I added the Sculptamold.  It took two separate three-hour sessions to cover the very large area of this new terrain work.  I used a stiff Sculptamold mixture to counter the steep slopes and the even steeper undersides of the many outcroppings.  Fortunately, such stiff mixtures set up a bit quicker--overnight versus a couple of days with wet mixes.

Filling in the terrain below Cruzatte completes most of the terrain formation along forty feet of my basement wall.  One easily imagines being in the mountains.  There is a lot less bare plywood showing!

SCENERY HATCHES FOR TUNNELS 9 AND 10

As I built the terrain shell for Noisy Creek Trestle (https://espeecascades.blogspot.com/2018/06/noisy-creek-trestle-and-tunnel-9-terrain.html) I realized I needed to retain a pair of footpads straddling the trestle area for access to the far back corner.  The need for those footpads was dramatically shown by one of the photos in that prior blog post, showing me up on the layout slathering Sculptamold onto the terrain shell. Those footpads needed removable terrain hatches.

I began the hatch terrain project by creating a duplicate set of baseplates to serve as footpads when the hatches are removed.  I then covered the scenery hatch base plates with slabs of Styrofoam to serve as bases for further Styrofoam construction.   Back profile panels were erected to match up to the existing terrain around Tunnel 9 and the RR-West portal and shed system of Tunnel 10. Side profile panels were added and a front profile plate for the Tunnel 9 hatch was created.  The scenery at the base of the Tunnel 10 hatch forms the creek and is at the same height as the base plate.

Terrain profile panels in place for both access hatches. Tunnel 9 is on the left.  Tunnel 10's RR-West rock shed is on the right.

With the edge profiles defined, I filled in the remaining terrain slopes with slabs of Styrofoam.  Some of the slabs were built up with two or three sections of my standard one-inch foam material to provide more depth for carving.  I then used spray foam to fill cracks and gaps in the shell.  Once all of this set, I shaped the terrain using knives and my Surform scraper.


Terrain shells for Tunnel 9 and 10 access hatches with spray foam applied.

Moving toward finishing the terrain shells, I needed to test the hatch removal.  Tunnel 10's hatch removed fairly easily, but the Tunnel 9 hatch proved very difficult to remove.  After much banging and exertion on my part, I found the front corner of the Tunnel 9 hatch extended a bit too much.  It both caught the fixed terrain profile in front of it and caught the roadbed at Wicopee when trying to lift it straight up.  Trimming work with my oscillating saw (a new tool acquisition this year) freed the hatch and allowed me to remove it.  I trimmed it further with my circular saw. The hatch base plate does not need to fit snuggly into the hole.  Only the terrain should be "snug."  


Tunnel 9 hatch with front left corner trimmed using the oscillating saw. This will remain a tight fit, but the hatch is now removable.

The final step in this project--for now--was to apply the Sculptamold covering to the Sytrofoam shell.  I used wax paper at the edges of the shells to retain an edge separate from the fixed scenery.  With these two terrain hatches built up, the terrain around Noisy Creek Trestle is a bit more complete.

THE RAILROAD AT YEAR SIX

Each year around the August 1, anniversary of the official start of construction in 2012, I do a photo survey of my railroad.  This helps me and you readers see what progress I have made in the preceding year.  Last year's post can be found at:
You can link back to prior years via a similar link at the top of each of the annual surveys.

This past year saw me make major visual progress on the railroad. Bridges, trestles (viaducts), tunnels and terrain have sprouted over much of the mountain grade portion of the railroad.  Prior years saw the primary construction, fleshing out of the initial core (finished just in time for the August, 2015, NMRA National Convention), refinements prompted by regular operations, and a beginning on structures for industries served by my railroad.  

This year's photo survey will follow the CZLAT (Crown Zellerbach to Los Angeles Trailers) RR-Westbound from Eugene to Crescent Lake.  This is one of the trailer and auto rack trains added to my regular operations in the past couple of years.  Those long cars challenge clearances and roadbed vertical kinks introduced during construction.  By late 1984, the CZLAT had developed from a mostly boxcar train to one with TOFC (Trailer On Flat Car) equipment as wells as the box cars of paper products (think "TP").  

This photo survey will include more photos than usual, befitting the major visual changes introduced this past year.  The captions will highlight those changes.


The CZLAT, running as SP X8283W, prepares to leave the Eugene Arrival-Departure Yard.  A full house in Eugene put the CZLAT on AD-Track 7 instead of the preferred use of tracks 1-5 for Portland-originating traffic. This past year we reversed the normal operating direction in the reverse loop tacks that make up the Arrival-Departure Yard.  This makes it easier for the Santa Clara Tower Operator and road crews to identify the motive power on RR-Westbound trains.


X8283W rolls past the Eugene Depot.  Many of the structures here were 2017 additions, seen in last year's survey. GP9s have taken over yard switching duties as I wrestle with electrical contact and other running issues on my fleet of SW1500s.


SP 8283 crosses the Willamette River between Eugene and Springfield.  


The CZLAT continues RR-Westbound through Springfield.  Springfield is a major industrial complement to Eugene. It looks like I should spend some time filling in structures and an initial scenery treatment here.


SP X8283W rolls around the Marcola area on the railroad.  I built that grain elevator more than four decades ago and it has followed me around the country.  It still serves well.


SP 8283 rolls onto the bridge over the North Fork of the Willamette River at Westfir.  The old Western Lumber sawmill complex continues to provide lots of carloads to the SP on this railroad!  This past year, I built up and finished the major sawmill structures.  I finally sorted out how to represent the log pond as an entrapment of part of the river.  This cleared the way to add the basic terrain shell to the area.


The CZLAT pokes out of Tunnel 22 at the RR-East end of Oakridge.  As a priority train with TOFC cars entrained, the CZLAT takes the mainline through town. Lower priority freight trains without the long cars are routed into the yard at Oakridge to have helpers place mid-train.  The CZLAT will get its helpers on the front of the train.  Tunnel 22 through "THE" Oak Ridge was bored during the Harriman era.  The Oakridge Turn power is in the foreground, waiting for its crew to come back after their eight-hour rest and return to Eugene by way of Westfir.  


A pair of SD39s are today's helper power for the CZLAT.  The SP bought SD39s for helper duty in the Tehachapi Mountains of Southern California and similar duty on other nearby grades. With their long end porches and full light packages, they are very appealing to me, so here they are, transplanted to Oregon!  

As alluded to above, SP operating rules required helpers to be placed on the front of trains containing long equipment such as the 89-feet long TOFC cars in the CZLAT.  My SP Dispatcher friend notes it was easier and faster to put point helpers on the train while occupying the mainline rather than entering the Oakridge Yard. Trains without the long cars do go into the yard to have mid-train helpers entrained.  That is a longer process which includes more time to make the air brake connections and perform an air test.  Today's CZLAT, though, gets the priority treatment of a point helper.


With the air test complete, the CZLAT begins the major climb toward the top of the Cascades as it crosses Salmon Creek, just out of Oakridge.


The CZLAT climbs up into McCredie Springs, one of the first major sidings above Oakridge.  Tunnel 21 is high on my list of future terrain forming efforts.


Climbing out of McCredie Springs, the CZLAT crosses the bridge over Eagle Creek.  I just finished this scenery effort at the end of July.


Here is a wider view of the Eagle Creek area, with Shady Creek Trestle looming above it.  That steep canyon needed to drain somewhere, hence the bridge over Eagle Creek.


Our point helper set emerges from Tunnel 20 as it climbs toward Wicopee. A train waits on the mainline above at Cruzatte.


Climbing out of Wicopee, our train crosses Salt Creek Trestle.  This is the longest trestle (viaduct) on the line. Highway 58, the Willamette Pass Highway, passes underneath.


Another view of our train crossing over Highway 58 using Salt Creek Trestle.


Our train skirts along the rock face between Tunnels 10 and 12. Tunnel 10 has open gallery rock sheds at both ends.


Noisy Creek Trestle spans between the rock shed portals for Tunnels 9 and 10.


The CZLAT meets an RVEUY which is holding the main at Cruzatte for the meet.  Wicopee siding can be seen below.  Though fore-shortened in my model, the tracks really do stack closely in this stretch of the Cascade climb.


Our train emerges from Tunnel 8 to cross Shady Creek Trestle and then plunge immediately into Tunnel 7.


Tunnel 5 has a long open-gallery rock shed at its RR-West end.


The climb is about over as our train crosses Trapper Creek after emerging from Tunnel 3 at the summit.


With the Cascades conquered, the helper is removed from the CZLAT at Cascade Summit.  The helper is joining another helper set on the Beattie Spur--actually a short siding. The helpers will await the pleasure of the Dispatcher for their return to Oakridge.  Depending on traffic and any urgency for helpers at Oakridge, the Dispatcher may send the helpers back down the hill light (alone) or may put them on the point of a RR-Eastbound to help a train downgrade with their dynamic brakes.


Journey's end on my railroad, the SP8283West rolls to a stop in upper staging at Crescent Lake.  Historically, Crescent Lake was the Division boundary between the Shasta and Portland Divisions of the Southern Pacific.  It had a modest yard and a depot with Train Order Operators for both Divisions.  This makes a logical end for my railroad.
