When I was about 10-12 my dad built me a huge (huge to me) model train layout - about 6x8, two track sets, lots of buildings, mountains, lighted towns, railroad crossings etc. really sweet setup for a guy that wasnt into model trains. Any who - my interests changed and that stuff got boxed away. Fast foward almost 30 years and my son found them in boxes in my parents basement. He is almost 7 and has seen model trains and thinks they are pretty cool. My question to you pro's is: Is it worth it to try and revive these old trains and track? of course on the cars and buildings, they are in decent shape. I have two engines and lots of track. Should I buy new track since it has been in a basement for almost 30 years? It doesn't seem rusty. Maybe something has changed in the past 30 years in model railroading that I don't know about. Where do I start? Thanks in advance.
