The Rocky Mountain Pacific is Bruce's Fn3 garden layout. Fn3 uses 45 mm (typical garden railroad) gauge track and a 1:20.3 scale ratio to model accurately 3 foot narrow gauge railroads.
The name is registered with the NMRA. It came from the idea of southwestern Colorado narrow-gauge railroads that were always short of cash and long on ideas. Everybody seemed to be planning on running to the coast or Mexico, when really they didn't have enough cash to get over the next hill!
The reporting marks for the Rocky Mountain Pacific are RMP. That can also stand for Real Money Pit.
This is being built in our back yard here in Goodyear AZ. It will use an NCE 10 amp radio DCC system.
Well, last winter slipped away without getting any major work done. Yes, winter. Here in Arizona, I don’t work on my railroad during the late spring, summer or early fall.
This winter, I had plans to get the track work done. A bout with shingles in my leg torpedoed those plans and I’m just getting back to where I can work on it as the temps are rising.
This week I got back to wiring the outer loop. Once that is done, I can level (right to left) and grade the track.
Back in September, I got an iPhone. I was playing with the panorama-photo mode of iOS8. Here is my photo of the layout at that point in time.
Today, we had landscapers remove some of the rock and dirt that surrounded the flagstone walk around the north side of the layout. A new sand base was installed and the flagstones releveled. Then dark brown ¼- rock was brushed in around the flagstones. The resulting walkway looks great and will be an approximate color model for the layout. I plan to use the dark brown ¼- for ballast and a tan ¼ - for the general ground cover on the final layout.
In the photo, you can see the (gray) conduit with the DCC bus wires coming under the new walkway.
During that time, I was sifting the dirt from the rocks in the mix that was removed. I’m using the ¾” rocks (Madison Gold color) as fill for the track support and then putting the dirt over it. When the track grades are all established. Then I’ll shim the track up ¾ inch with stakes and ballast it.
Wiring was started with the reversing loop all bused together and connected to a PSxAR auto-reverser. Wiring of the two districts and installation of PSx circuit breakers is next on the wiring list.
Well, we are now out of the triple-digit temperatures and outside work can start again.
I cleaned the track and ran a few passes.
Made some photos and video for my Model Railroad Hobbyist column - CLICK HERE TO READ IT.
I did some coupler work on cars and tuned up the C-16 for a You Tube video - CLICK HERE TO WATCH IT.
Next comes track wiring, followed by leveling and grading.
I waited until twilight last evening to take these photos. No shadows to deal with. The first one is the overall view, similar to what I've been posting since track work began. The second one is the area of the relocated rock and relaid track. Leveling and grading continues, but a bit more slowly, as daytime temps are in the mid to upper 90s and we even broke 100 in late April. See the weather panel in the sidebar.
Today, two days of marathon track laying resulted in having all the track down.
The outer loop (out of this photo on the right) needs a bit of realignment after a large rock is slightly relocated. Locos that are 1:24 will fit through the curve, but 1:20.3 units will hit.
Now the tweaking, leveling and grading begins.
I also got a storage shed. It is currently full of gandy dancer materials with a few cars. Eventually, it will store the RMP rolling stock.
The RMP even had a revenue run with midgets (1:24 folks) running behind old #4, seen here in front of Big Springs Lake.
Today, I spent some time on the yard, engine service facility and a few other issues. I can now run two trains on DC on the two loops, they are isolated.
Started out to do a couple of hours of track work today.
As progress was becoming addictive, it stretched into 8+ hours. At the end, I was running on the outer loop!
Just some spurs and the reversing loop left to lay.
Then on to leveling and grading.
I spent yesterday afternoon on the inside loop of track. Got enough down to run a loco around the loop. Nothing is graded, leveled or ballasted. There are no bridges - just track being held up by wood sticks. But this little LGE tank has been running for many hours last evening and today. I've got lots of turnout rebuilding and reworking and bridge buildsing to go before any more track laying will be fruitful.
The hardscape was done by the landscape contractor today and I've started laying out the track plan. I just put track on the ground to see how my plan will fit. I found some issues, but have most of them ironed out.
