Neither do I. May be a static effect or just a simple wearing effect of the plastic itself.
I use Intermountain metal wheel sets in Athearn Delrin trucks and I almost never have a problem with dirty wheels or track. The Intermountain wheel sets are fairly heavy and have a plated surface that imitates an actual polished wheel tread. I prefer them to NWSL wheel sets for these reasons.
Yes!
I agree with bob2 that we are talking about four different hobbies, all sharing 5' gauge.
Pennsylvania trolley gauge is 5' 2.5". It's still in use in New Orleans and Philadelphia.
