Wiring the Maple Valley Short Line – Part 2

The Maple Valley Short Line RR is now operational. I can successfully run two trains simultaneously on two long lines. The outer loop rises to four inches at 2% starting at the Maple Valley River Bridge. The inner line completes a circuit by passing through two tunnels, crossing the Maple Valley River, and winding through the village.

As every model railroader knows, operational does not mean finished. The outer line has been running for several months. Last week I finished wiring the inner line and all the sidings. I decided to use Atlas Selector Switches rather than soldering DPDT toggle switches. I may yet change my mind about that. I plan to wire LED turnout and block signals on my control panel. The panel in the photo is temporary.

Last week family members came just to see the layout, so I had to finish the track wiring and make sure it all worked. I discovered my small furniture dolly with a piece of plywood works great as a cart allowing me to move around under the layout without kneeling and bumping my head. Wiring was a much simpler task as I avoided stops at the first-aid closet to bandage cuts on my head.

To you expert electricians, this is nothing new. But the slickest help I found on YouTube is using “heat-sinks” to keep my plastic ties and wiring insulation from melting. Two little alligator clips worked perfectly! This is the first time I used buss feeders on both rails, so I did a lot of soldering.

I staggered the feeders on the track. I used black wire for the common feed, red wire for the block feed. I put a number sticker on each block feed to correspond with the Atlas Selector Switch. (Now that the track is wired, it’s time to complete ballasting.)

I took a lot of time thinking about how best to run the wiring underneath the layout. I was not careful with the underside of previous layouts so I had different colors and wires running in every direction. It was a real mess when something stopped working and I had to figure out why.

I used 14 AWG solid wire for the buss feeds from the power supply. I used 20 AWG solid wire as the feed soldered to the rails. As you can see, my 14 gauge power feed is green, the 20 gauge feed to the rail is red. At this point, instead of soldering each feed connection, I used wire nuts. I plan to go back and solder later. (You’re right, unless I start having problems, that probably won’t happen.)

Assisting me in the project, not only so I can see, but also working the magic of battling SAD (Seasonal Affective Disorder) I struggle with every year, is the sunlight lamp our daughter purchased for me. It works! Instead of feeling like crap when it’s twenty degrees, dark, and snowing, I feel like jumping, running around and laughing. Not really, but it does help.

All the while tough work is going on under the layout as I scoot around taking care not to cut my head, these guys paddle down Maple Valley River like they don’t have a care in the world. (Current ripples on the surface will be added some time down the road.)

It was an exciting moment when I was able to sit back against the wall on my little cart under the layout and admire the terminal strip complete with buss feeds in place. The black wires on the right are the common feed and I used jumpers between the three terminals. The rest of the terminals are numbered from left to right, with number tape on all the wires. Turned out nice. Troubleshooting will be much easier.

I still have the big but fun job of wiring all of the turnouts, signals, and buildings. I plan to find some street lights for Maple Valley.

The Maple Valley Short Line Railroad has been a long and satisfying project that is no where near completion. But that is the fun of model railroading. There is always something more to do. Whether it’s small weeds along the river and around buildings, kids playing in a back yard, townsfolk going about their business, neighbors arguing over lot lines, or a train load of tourists stepping off The Old General into the wonder of Maple Valley. Which is still stirring over the disappearance of Sylvia Meisner. It has been months since anyone has seen her. There are still no clues to her whereabouts…or are there?
