Good morning, thanks for the welcome words.

N gauge is not for the older folks...lol. It is hard enough to see what I'm doing building HO locos.
I know two guys who have N gauge stuff and might be able to help you:
Chris Benadie from Stilbaai cgbenadie@gmail.com and
http://www.modeltrainsonline.co.za/Heinz Shultz from Dana Bay hrs100@telkomsa.net
Chris have a few of my locos that I've built for his HO layout.
Have a good day,
Eric.
