I am ready to begin building a long awaited layout. I have considered all the track options but would like some opinions. I have heard great things about Lionel Prewar T-Rail track and am considering using it for the layout, although I do know it may be hard and expensive to locate. Would this be worth doing or should I just use Lionel O-Gauge track which I already own? What makes T-Rail better than O-Gauge? At this point I am thinking I want to stay old school and use the old Lionel track systems. Thanks for any help!
