Growing up in the mid fifties to early sixties period, I collected numerous Lionel trains and accessories. The pieces range from around 1946 to the early sixties. The collection has been decently stored. However, the tracks (O and O27 gauge) has seen better days ((kinda like me!). Can I use the newest Lionel Fastrack with my collection or should I stick with the tubular track? Also, are the transformers (ZW, etc.) from the earlier era compatible with the track systems available today or should I plan on new sources of power? Thanks in advance for any advice you can share!
