I have a ten inch section of atlas straight track that has been giving me problems. I had trouble with engines stopping there in the middle of the track section. I took it out of the main. Using my vom I could not get a constant O reading on the ohm meter. I would put one end of the probe on the center rail and then the other probe on the other end. The meter would flash different numbers constantly and as I slowly moved the probe towards the other end of center rail it would never stop on a number steady. I tried the outside rail and it would show 4 ohms solid as I slid the prob along and did this on each rail.
Suspecting the black rail had something to do with this I lightly sanded the center rail top until shinny. Now same meter test again and still did the same thing. I cleaned the top of the shiny steel rail with acetone and tried again and same thing.
I then checked another straight section of atlas track and the same thing, good outside rails and bad center rail. Will call atlas and see what they say as I have quite afew of that track, some good but most bad. It has been in the box for about 4 years.
Any ideas?
