a few years ago I inherited my Dad's 1956 Lionel O gauge train set. It sat up for the better part of 30 plus years, minus one last setup he did about 11 years ago (one last time for him). At any rate, the track is in need of a good cleaning. It is oxidized, some rust, dirty, etc. Can anyone advise a newbie on how to go about returning the track to pristine shape? I dont want to do anything that would hurt the value of the track, or damage the cars that will run on the track in any way. ALso, does anyone know of a model railroad club in the Dallas/Ft. Worth Texas area, perhaps one that would have some O gauge people? Thanks so much, in advance, and I look forward to learning anything I can on this forum!
