One of the challenges of a track-powered
railway is getting the power out of the rails and into the locomotive and
cars. Clean track and clean wheels are a necessity and as such are the
toughest thing to maintain. Cleanliness is next to impossible, but we don't
stop trying.
After
showing up in a couple of places with my little track cleaning setup in
hand, I had several questions about how/if it worked. I've also mentioned the "Maintenance of Way cut" several
times in the Pictorial and thought you might like to know a little more
about it. As I've said, on a rail-powered garden railway keeping the track clean for good
electrical contact can be a pain. Many people have come up with different
ideas on how to solve this problem. Here's what I've done.
This method of rail-cleaning builds on the idea of legendary
HO modeler John Allen. He used a fibreboard of appropriate size, slung
under a boxcar. I up-sized this method, using the 'rough-side' down, added
weight and discovered it still didn't work that well. I added drywall
sanding mesh of 150 grit and my track stated getting very clean. Then I
realized this method needed less weight on the slider, or I was going to
prematurely wear away my track! There is a delicate balance between amount
of weight used and the coarseness of the mesh. I've tried both 220 mesh,
which clogs up too easily, and 120 mesh, which leaves marks in the track!
I've also discovered that Mr. Allen's original idea still has merit. I used
a second car, following the 'mesh' car, which seems to polish away any oil
or other muck. Both need regular cleaning, but seldom do I have any
track-surface conductivity problems. |
