Re-ballasted Corinna yard

I forgot to mention that I had decided to re-ballast the yard at Corinna. Previously, there had been a lot of greenery growing up between the tracks. After going back and looking at some pictures, I realized that there was very little of that on the Maine railroads. I basically just ballasted over the greenery. It’s still not perfect, but it’s better than it was. At some point, I’ll go back and dirty it up a bit, and I think that will help.

I also promised to show you a little of what’s been happening in the creek. As of now, it’s still a touch milky, and it’s going to need at least one more layer of water poured.

I decided that the rocks I had placed previously were not appropriately colored, so I used a couple of shades of gray acrylic paint to correct that. I also placed some more smaller rocks and some additional greenery.

Newly colored rocks, “rapids,” and second water pour.

Today, I moved on to the turntable. I have been considering using tiny Neodymium magnets to align the table with the tracks. But, I was concerned about the accuracy required in placing the magnets. Kevin came up with a great idea — and a new shape magnet — to make it relatively easy!

Most of the magnets we’ve been looking at so far have been tiny flat disks, but Kevin recently received a new, cylindrical magnet.

Magnets used to align turntable bridge with tracks

Magnets are placed in the pit wall, under the center lines of each service track, and under the center line of the bridge track. In this case, the approach track is directly in line with one of the service tracks, so no magnet is needed there.

Kevin’s idea to make the alignment adjustment possible is really simple. We drilled over-sized holes for the magnets, and inserted steel flathead screws. The cylindrical magnets hold to the head, and can be slid around slightly. Once the correct location is found, the holes will be filled with glue.

The magnets hold with enough force to stop the turntable at the appointed spot with authority. In the long run, I’ll be using a motor to drive the turntable, but I think that the magnets will still present enough force to align the tracks.

Parting Shot

I know I promised an updated shot from the creek area, and, even though the water’s still a little murky, it is a lot better. So, here’s another shot of No. 9 crossing the creek:
