I picked up a Lionel O-27 trainset as a Christmas gift for my father yesterday at the OKC trainshow, and since he hasn't owned anything Lionel for about 40 years and I never have, I have some questions. The set runs pretty well right now, but is there anything I should do as far as cleaning or lubrication? The set was made around 1955 and any instructions are lost to time. The track has a little corrosion to it and I purchased some Emery cloth to improve electrical contact. Good idea or bad? Also, the guy who sold it to me included a bottle of smoke pills. I haven't tried them out yet, and the smoke "box" looks to be in good shape. How is it supposed to be cleaned? I imagine after 50+ years of use, there has got to be some build up inside. I guess what I'm really asking is if anyone can point me in the direction of an owner's manual. Online is greatly preferred, and since I live in a non-trainshop town I can't go and buy one. Sorry for all the questions, but this is a whole new arena for me. And after comparing it to my N-scale stuff, all I can say is Wow! Huge! Thanks.
