Hi there. I bought many train sets in the 80's and 90's, thinking in the days of my retirement. Everything was packaged in a box, and now I find that all my stuff works with another technollogy, of curse.
What are the new things, in resume, that I have to consider to enjoy actually this great hobby?
Could anyone give me some advise?

Hi, I am new in this forum.
I know there is no more pancake motors in the market. Can I replace this motor, for an old Bachmann locomotive, with a newer one (new technology)? Everything else is new. Thanks.
