I wasn't sure which forum this belonged in so i decided here , if it the wrong one let me know so i know better next time. I would like to read opinion on rolling stock trucks. I don't think a "question" perse would be appropriate as there are a bazillion differnet types of trucks and i'm sure they all have their merits. So far in my collection i have: 1) all plastic w/ a cone end in plastic holders (<== wrong term i know but i'm still a pup in model rr'sing terminiology hahaha), 2) metal axles w/ plastic wheels w/ cone ends in plastic holders 3) metal axles, plastic wheels and metal holders w/ cone ends 4) i think i have one car that has metal wheels and holders My layout lacks diversity in rolling stock and i've been trolling ebay picking up what i can on the cheap to see how they all work. I've noticed that the metal alxle and metal wheel cars (both by athearn) are almost frictionless vs the all plastic jobbers that i think have little brakes on them that are always on haha. I'm going to slip a question in: Is there a way to rehab the plastic crappy ones? And can somone point me to a cheap place to purchase better trucks (insert correct term in place of trucks)? I noticed there are a couple other new folsk joined in so maybe we can osmosis some wisdom from the old timers.
