Two things led me to make some fairly major changes to Nelson, the largest yard on the layout, and one that has its own assigned switch crew (and possibly 2 in the future)
The first was a comment from the yard crew, mixed in with others from my last op session, that it would be nice if Nelson had a yard lead so the switch job wouldn’t need to clear the main. No problem!
I decided to pull out 2 of the 3 switches at the east end of Nelson, push the main track outside of where it previously met with the yard lead, and effectively double track it through Procter. I also put a crossover in where the east siding switch previously was.
Removing the 2 switches from the east end was easy, but turned out to be fantastic, as even though they were cut to fit a specific space, they fit perfectly in with the new switches in Procter!
Original position. At left is an industry track to various warehouses, centre is the main, the MLW S2s are on the yard lead, and to the right is the shops.
With switches carefully removed…
…I took them to their new position, and cut out that precise length of track.
Then I installed them by sliding the rail joiners completely onto the turnouts, and then sliding them back once in place.
Now, the crossover was difficult. I couldn’t fit a pair of turnouts into the space available as a traditional crossover, so I opted to use a curved turnout on the main. A Fast Tracks 30″/20″ radius #8 turnout would fit, but I wouldn’t want to spend $150 on a fixture for a single turnout. So I downloaded their template, printed it out, and went at it! I made sure to bend all the rails to just the right curvature and shape before soldering them down.
It ended up being very sexy, even though it took more than twice as long to build as a regular turnout! I installed it across from a normal #8, making the S curve very gentle.
I use Ribbonrail track alignment gauges on my curves, and in this case, I used it to keep the curve flowing properly into the switch as I laid it.
I throw my turnouts with servos controlled by Tam Valley Octopus IIIa boards, and to save on outputs, my crossovers are thrown by a single output together.
So far, it’s been operating nearly flawlessly. Huzzah!
There are more changes to tracks that haven’t been laid yet. Let’s look at the plan again.
I’ve had issues with JMRI not being able to move all the cars it should, and it’s due to limitations within the yard. Look just below the diesel shops and left of the roundhouse, and you’ll see the RIP (Repair In Place) yard. I had 2 tracks in the original plan, and I was simply going to put bad ordered cars there until I could get to them.
Instead, I moved things around so that there were 4 tracks of the maximum length that fit (#5 ladder) to use as an overflow for the class yard. I may even end up building the shorter trains, such as the Creston turn and my Tadanac wayfreight on them. (The second may be short lived, however.)
I also moved the drop-down wye further into the aisle. It’s still up in the air whether it will be built as such.
Lastly, I moved the top right tracks a bit. In real life, the merchandise terminal is on the north (aisle) side of its tracks, but I moved it to the far side so the switch crew could actually reach it!
Time to have an op session to test this out.
