Well, I’ve been focusing so hard on Past Matt/Future Matt on youtube that I kind of abandoned my blog for the past year. Back on track now, with no pun intended! (And apologies for having such inertia..)
I updated my post on programming realistic lighting effects to include NCE decoders! https://kootenaymodelrailway.wordpress.com/2012/11/29/programming-lighting-effects-on-tcs-and-digitrax-123-decoders/
This comes in light of the fact that I finished Cuprum Junction in Grand Forks – The interchange with the GN line to Republic and the hi-line. In fact, I have laid all the track on the Boundary Subdivision! Save staging, that is – The swing gate that sneaks beneath the duckunder is a bit daunting, but the first thing I’ll lay if I start doing track again.
Wait, what do I mean if?
Well, I’ve spent the last half a year laying track and putting in electronics, and with the amount of the stuff I’ve done in that regard I am SO ready to do something else! On the other hand, I’ve done a TON. Instead of the track only being in the area of the pulp mill, it goes up a 2.6% grade out of the top of the helix, through the short Shields siding, through a short tunnel, across the tall link and pin Farr Creek bridge, into the 1km long Bulldog tunnel (1500′ modeled) before soaring over the duckunder at Farron Summit, where there’s a 2000’ish siding, wye, lumber spur, and various MoW tracks. From Farron, it tips over down a 2.6% grade, winding its way around a small pond on McRae creek before entering Paulson canyon, with its towering cliffs, tight curves, tunnel and snowshed, often avalanche ravaged on the wet side of the Monashee mountains. Further downgrade the coniferous trees thin out as the line soars high above Christina Lake on the dry hillsides around Fife, a very short siding with a lumber spur and limestone tipple. The bottom is reached at the Kettle River bridge at Cascade, the longest bridge on the layout at over 500′ long! On the west side is the Grand Forks Sawmills and Cuprum interchange, all tucked neatly together in a little package. Another crossing of the Kettle River using a truss bridge reaches Grand Forks proper – I may do a history post later – and the wye, 3 track yard, and long passing siding with many varied industries. Great spot to turn around as you reach the end of the layout!
You’ll want to see some photos, of course.
The first section of new track from the past year, Shields siding:
This siding prototypically was above Shields Creek, with a medium length siding for loading lumber. Today, the Shields Forestry Service Road crosses the abandoned railgrade here, where a picnic table and outhouse sit across from the hidden foundation of the old station. On my model, the siding twists in a tight S curve over a high fill – A scenic feature I’m excited for.
After wrapping around through a tunnel, the line crosses the second of the 3 major bridges on the line – Farr Creek
Though this may not be constructed for an eternity due to its unique nature, the scenery presents some constructive difficulties. The front of the benchwork could not be very high, even though it was dropped down for the valley, due to the height of the hills on the lower deck. What you see is the best compromise.
Next is the Bulldog Tunnel:
This is not going to be an obvious helix, with the track disappearing into a near-prototypical hill on both sides of the ridge, with a backdrop to top the scenic divide. Originally, the line completed in 1900 used a series of switchbacks (5 on one side, 7 on the other) to get over this ridge, but the 1km long Bulldog Tunnel was completed 2 years later. With a slight curve at the west end, this was unsettling to bike through – No light at the end of this incredibly long bore!
We get into the almost-scenicked are at Porcupine Creek
Porcupine Creek was originally one of the CP’s famous wooden trestles, until it was filled in like so many others. Trestles are cheap to construct, hard to maintain, and make super good kindling. This is the most major side valley in the Dog Creek valley, which we follow to the summit.
At the summit, the wye leg winds prototypically toward a side valley before unprototypically slinking behind some hills with its long tail. You can see that I’m experimenting with a bristol board/hot glue lattice in this area.
Past the summit is a bunch of windy track that will eventually be snowsheds, tunnels, canyons, and loads of interesting stuff. The landscape changes from a high mountain pass to lush forest to near desert, an incredible variation that was found in only 19 railway miles of the prototype! Near the bottom is the Fife limestone tipple, a 2 car lumber loading spur, and runaround track. The level tipple track makes a huge visual impact highlighting how steep the grade is, much as in real life!
At the end of a solid 2.65% grade we find the big Kettle River bridge:
At over 500′ long, this is/will be the longest – But not the highest – bridge on the layout. The backdrop behind hides the Great Northern Railway’s Carson spur staging track, enough to hide a small train.
Next is the biggest industry this side of the pass, Grand Forks Sawmills. I designed this to be an interesting track plan by itself, and was fairly faithful to the prototype.
On the near (north) side, there’s the lumber loading sheds, the far side has the chip pile, there’s a runaround and potential loading track that may be used for switching, a potato warehouse from a mile down the line, and smack in the middle of everything is the GN Carson Spur! Today, this is the only operational part of the Boundary sub west of Castlegar. The Grand Forks Railway sporadically serves the sawmill, interchanging with the Kettle Falls International, which bought the old BNSF/ex-BN/exx GN line up from Republic, Washington.
Zip across the smaller Kettle River bridge and you find yourself in Grand Forks itself.
A nice little yard, perfect for handling sawmill and interchange traffic. As you can see, the track zips through the backdrop. This will eventually lead to the upper/west staging, but I’ll need to build a swing bridge and I am DONE LAYING TRACK.
The east end has seen some work, too, though not much.
Nelson yard is home to some 60 billion – or perhaps just 52 – turnouts, not counting the Kootenay Forestry Products sawmill and Procter yard/barge slip to the east. I couldn’t stomach or justify laying that at the moment, so I laid all the west end turnouts, 13 in all, to get the first 5 tracks in to be used temporarily as staging tracks. Just 40 more and I could have the whole yard, except I don’t care! Hahahahahahahahahahahaha! I think I have turnout-brain.
So, you say, this guy has a lot of turnouts, how does he control them? Well, the cheapest solution would be solenoids, but those would snap my points right off. I instead use 9g servos controlled by Tam Valley octopuses. I’m working on a youtube video to show all of this, and I won’t duplicate that here. Have a link to part 1 and part 2 as they are up, though!
Temporary control panels are in, and I’ve retrofitted servos onto all the mainline switches in the Castlegar/Kraft area. Those DPDT slide switches I used earlier just don’t last.
Lots and lots and lots of wires, oh yes! I never do things the easy way.
That was a TON of work condensed into a long blog post, I hope I can update more regularly now without the weight of this hanging over my head!
In addition, I’ve been trying to get some more operational sense into my layout. You’ll have noticed the yellow post-its hanging out on the side of the roadbed. The show both passenger and freight speed limits, as well as the mileage. These hopefully work in conjunction with the timetable that I created…
I hope that makes any sort of sense to someone with experience with TT&TO operations.
Well, that’s my hundred dozen words for the day! If you made it through, high five!
