Hi.. I moved to the US some time ago and brought with me an extensive (locomotives, rolling stock, track etc.) OO gauge collection that was originally my fathers and then mine as a boy.
I've recently renewed my interest in building a layout here in the US but other than knowing that HO and OO are compatible can anyone provide me with any pointers to get me started in being to build a layout using my (very) old gear but using US power supplies and controllers as well as any other complications I may not have considered??

Thank you.
