@Choo Choo Charlie posted:I believe the major cause of pick up roller wear is the gaps between track sections, at least for 027 track. I know the Super O track has a thin center rail verses the two tracks and do not know if it has gaps like the other types of rails. It believe the thin profile of Super O center rails may lead to deeper curves on the Super O pickup roller...

Charlie,
I'm sure that the copper connectors that clip on the center rails of Super-O track sections may often add to roller wear. Especially as a young boy, I'm sure that I didn't place and press the clips perfectly on the middle rail of adjacent sections of track. This would leave an end of the clip sometimes sticking up, with a slightly sharpened point hitting the rollers. Over time, this could create additional roller wear.
