I'm thinking of trying out some narrow gauge.  All the screen shots that I have seen of narrow gauge has gotten me interested.  I have NO narrow gauge items on my computer.  What I'm looking for is a small but interesting route/layout with all the dependencies on the dls.  In case I don't get into narrow gauge I would like to be able to disable the dependencies so that my computer is not cluttered with a lot of stuff that I won't be using.  I also will need 1 or 2 loco's and some rolling stock.  I'm using 06 but 04 is on my computer so either is ok.  Any suggestions?
