Hi all!

I live in Brazil and I am 51 years old. When I was a child I used to play with model trains, and recently I got a lot of Lionel trains, without controller, tracks etc. Please, see pictures in the album Lionel Trains:

So, I am thinking about playing again but I need to fix them before and build a model railroad. So, anyone could  suggest me the best option to start? Any help will be appreciated. Many thanks!

By the way, sorry about my english.

Best regards,
Alfredo Manhaes.
