Reply to "Another stumper: Two identical BiPolars with PS3 run at different speeds"

Thanks Anthony and John. Am not sure about the # of stripes...I already put it back together...but is it worth counting the # of stripes on the two bipolars - could the factory have installed different #s of stripes on each, would this explain the difference in speeds?

I conducted more tests at high speeds last night. Now, with about 2 hours break in on each, and at 32 scale mph the engines pull apart within a few minutes; after 10-15 minutes the faster one is a good 7-8 feet ahead of the slower one. I am hesitant to lash these two engines together. The faster one would not only be pulling the heavy consist but it would also be pushing the slower one...
