Most mainline turnouts found on SP's Cascade Subdivision  used Class I railroads typically mount their switch motors on use a doubled tie arrangement to mount their switch motors on

So I scratchbuilt my Eugene yard full of code 40 turnouts, with a design that got rid of that oversized throwbar we have all become accustomed to.  Hopefully when I get far enough along, Proto:87 will still have their turnout details for N scale to complete the point bars.  Here is a proto image by Thom McAdams of a switchstand / throwbar arrangement on a single extended tie depicting a typical SP common standard:

Another image can be found at:

Note the throwbar is basically just a rod to the point bars, and is not some huge tie sized plate (that is sandwiched between two adjacent ties), moving the switch points back and forth.

Well that is all fine for branch related trackage, but then news comes along that the SP had a whole different way of doing things at their Eugene Yard.  Ron C sent some images to me that depict a completely different configuration than when I had started the project... this is an image of an old SP "V" plate switch configuration provided by my friend Mike O:

I've been cleaning up loose ends on layout trackage in preparation for a mass weathering campaign,  but now I have to deal with this revelation that recently came to light.

These were designed as a Variable Switch, where the switch crew could drive into the switch opposing the switch points from either side, and push the switch points to either side where the turnout would remain in the last traveled position.  Unfortunately this configuration used two ties for the ground throw (instead of switchstand), and now I am stumped on how best to recover from this revelation of data....  Here is a sample of my after-the-fact tie placement, but I dont like it:

One solution is to go back to a switchstand.... but not proto at this yard.    :(
Currently mulling over the lack of options...

Cascade Sub Ops Sess Changes, and Update

   No Ops on the RR since last.... June.  Wow, didn't realize it took that long to get the new business location up and running.  Last time I even had time to work on the RR was when John and Chip came over to help around xmas.  Now that our shop is open for business, I am able to resume work on many things around the house, including the RR.  As preparations were being made for our first ops sess of the year, news came that our signalling / communications engineer had been hospitalized.  We are all trying to remain optimistic on a speedy and thorough recovery.   Intent is to start ops on a regular bi-montly schedule (on the same day of month), from a revolving call list order so that I have less coordination to deal with, and crews can either sign up ahead, or wait for a harassing call during the interim.
   Issues with sound decoder stability, and a rare intermittent false overload issue (since rewiring some of the power distribution sections), were mostly resolved due to a mis-wiring issue in the staging yard, as well as the installation of a new 8 amp power supply... Time will tell, but preliminary testing appears quite optimistic.
   I have installed all the remaining sections of curtain, except for a few that still need a bit of finish trim work.  To complete the look from layout height down thru the floor, I am finally filling in the remaining cushioned floor tile sections that were 45 degree angle cuts and partial sections.  This just seals the overall black finish look, which Im having a hard time getting pics of due to the black colors lacking any detail.... it looks pretty sweet (IMHO).
edit- phone pic added

   Eagerly awaiting the release on Wheels of time Flats, Bulkead Flats, and their most recent announcement, the Evergreen PC&F Evergreen boxes (woo hoo).  The MT SW1500 should be out any time now, and looking forward to doing a tug-o-war with one of those and our modified tungsten LL SW1200 yard goat.
     Looking out the back door of our shop, is a bit of mainline action, and bagged this phone pic of the Oakland one afternoon:

Thats the shop down below in the right corner.  That shot made me do a double-take with that kids face on the container behind the power...  Regular traffic passing by with a step out the back door, is currently down to the daily Rock train (with three sets of distributed power throughout), the Oakland, Saugus Local, and boring parade of commuters.  Hopefully traffic picks up again soon.
   Back to work on the SP Oregon Division.   :)

Cascade Sub New Year's Update

Over the Holidays I have been able to make some layout progress again.
The last of the curtains are back from the seamstress (Thanks Mom!), and ready to be hung when all the dust settles from latest scenery work.
 Trying a new approach to scenery construction instead of the old plaster ways.  I dont like how my pine trees repeatedly lean over in the plaster shell if you look at them wrong, and also wanted to see how use of foam techniques would play out.  Foam will allow for stabbing those pines in without revisiting for maintenance, and sculpting of the contour more accurately than trying to camouflage a bunch of humps and ravines / crevices via multiple passes.  Most notably, there are a number of locations with long benchwork spans that I think the foam will save some grief (not user friendly areas for cardboard lattice), like for the main river crossing contours below and around Hampton bridge.  Also I have some narrow areas that need a plethora of conifers to convincingly force the viewer's perspective at both ends of Hampton.  So Chip and John motivated me to get going by offering to come up and help out, where we made some good progress on installing the scenery base foam for the Expansion section.  This was my first adventure using foam, and grateful to them for showing me their techniques on working with the stuff.  Unfortunately the expansion section is mostly all curved radius, significantly slowing our productivity.  It looks like a good number of man hours still left to get all the foam down and shaped there, plus a few sections that need it on the lower deck as well.  Thanks for gettin me off to a good start guys!  It wasnt as bad as I thought to clean up the foam remnants the next day, but still a little more work as compared to just regular sawdust (think static). 
Here is a pic that Chip bagged while we all contributed to spreading the mess out in the driveway:

I think next time I will hook up the shop vac first, then cut and shave it all in the bed of the truck for easier clean up.... (no I won't drop the tailgate at 65mph.... lol).  
Got a number of scenes off to a good start, including these areas where Chip caught a couple more images of the early progress...

fitting pieces around the lower deck of Hampton siding:

Kinda' taking a liking to what can be done with the pink stuff... but gonna have to drag these guys back up again to continue making any decent headway.   :)
Happy New Year!

Good-bye MT / Athearn, Hello WOT

 OK.... as Clark says, "Easy heart, just be still"....

Wheels of Time has announced the popular SP F-70-10 and 12 series flats that were abundant in lumber service over SP's Cascade Subdivision.  This has been a car long overlooked by the manufacturers in N scale.  Not only am I looking forward to two versions of standard flats, but also their bulkhead version (the F-70-26)!  Here is a link to check out their pdf page with the WOT SP Flats.
I will be retiring all my foob stand-ins that have been on the layout... some for decades, in exchange for the correct SP flat types.  Hope there are some buyers for that junk on ebay, as I got a large fleet to change out.
Here is some more info on the standard flats from Lee Gautreaux's website:
http://www.railgoat.railfan.net/spcars/byclass/flat/f070-10.htm
Anyone with additional info on the F-70-26, forward it this way, as info seems to be a bit scarce on the bulkheads...
Time will tell, but they are talking more road names, as well as lumber loads to fit.  Hope they meet or exceed Hay Bros in the latter, as they have set the bar pretty high for off the shelf lumber loads...
Not much else has taken place on the layout due to growing the new business, but we've been tinkering around with new PSX-4 power district boards, as Ray pushes me to keep from forsaking the layout all together (thanks Ray!).  Been dreaming about the next time we can squeeze in another ops session, and also need a push or more volunteers so we can progress further on scenery to cover up more plywood....

SP Cascade Subdivision Update

Last few operating sessions here on the railroad, we had the track section between Hampton and Summit drop Line-ups, which the dispatcher had set for through trains.  It wasnt until Ray was sitting in front of the computer during the last session watching the layout, when he noticed what was causing it to happen.  The switch at East Oakridge momentarily dropped out of correspondence for a moment, which is all it takes to knock down the signals on both sides.  We have been using the Tortoise internal contacts for relaying switch positions to the IO cards in the CTC sections.  It appears that the reliability for the contacts is good for power routing, but lower power applications seem to be a bit more fussy as the contacts wear out over time.  Over the years we have had a couple other machines that had the same issue, but we simply replaced them (some of these are almost 20 yrs old).  Instead of just replacing the machine this time, we set out to try a pair of limit switches externally mounted to the case.  These switches are less than a buck a piece at All electronics, and were quick to mount with ACC.  Here is a pic of the installation:

 After wiring and testing, we noted the paddles had too much spring tension for the motor to completely move over to its normal stop positions.  Suspecting the old motor might be getting tired, we opted to reduce the value of the in-line resistor on the Tortoise motor feed to boost the voltage up a bit more (instead of repositioning the limit switches).  This sped up the "slow-motion" rate of the throw-bar a bit, but gave the motor enough torque to regain its normal operation.  If this procedure ever needs to be done again, I will try mounting the limit switches a bit farther away, but anyone using more than 5-6 V power feed to the motor should have no problem as is.  The near completed project (wow, I would never allow bare wires and that sloppy work on my layout... lol):

CTC Dispatcher Panel

The addition of the peninsula expansion project changed the old panels that handle the signaling.  Ray has contributed countless hours in reconfiguring the underlying parts that make up the hidden workings of the layout in its new configuration (thanks Ray!). Updated screenshots of his latest panels have been added to the CTC Signaling Project Archive Page here (scroll to bottom of that page to view)..

Layout Signal Progress

Been working on the H2 Target Signal Project now that the CTC system has proved its stability working with the latest expansion project.  Progress on the signal construction has been added to the CTC Signaling Project Archive page found here (scroll up from bottom of page and find update 03 / 2014).
