Yours truly has a piece in there about his visits to loco sheds in the mid 1980s, but there's some worthwhile reading material in there as well, so don't let that put you off! Nothing specifically N, but the article on 3mm/TT might amuse -- the author argues it's the ideal scale, and I've heard others say the same thing. Hmm...
Cheers, NeMo
