Hi all - I've just got back into Lego and the trains after digging my old 12v system out of the loft and setting it up for the first time in 15 years! My layout is the same as when I was 14 (based upon one of those in the 7777 book) so I'm looking to extend and expand it in the next few months to make it more elaborate, run a few more engines etc, so will probably have a ton of questions to ask the more knowledgeable people on here (I've already got a load of useful advice just from browsing old 4.5v/12v threads!)!
