I'm a Johnny come lately to this site, rmweb is a total labyrinth with great goodies tucked away. it's nice to know you've got baseboards which have a history and character all their own, due to alterations,change of use,new ideas and so on. A line I'm working on at present has similar boards with a tale of their own. One iron I have in the fire is a b.g. Layout, also terminus to fiddle yard in small space, so I must follow your work carefully, although I'm working in 7mm rather than 4mm. I'm also planning a traverser run-round tucked away! (Great minds and all that) One trouble with minimum space broad gauge lines is that the points are such a hell of a length, so I'm all for ways to lose them. I've done some track, I read somewhere that vignoles, flat bottom, rail was also used on longitudinal sleepers besides bridge rail, so I'm using some ordinary rail, soldered onto copper clad sleeper sTrip from Marcway. the rail goes on the transoms, and then the lengthwise bits are cut to fit between the transoms. this way you can get the gauge set easier, and lay track panels as units on the board. beyond that things are in a state of flux. I've got a goods wagon fleet which I'm happy with. (One of the great things about being in the broad gauge society is the great kits and information that's available) There's four six-wheelers about half way through, and two engines with running chassis and superstructure to finish, so slowly getting there. Anyhow, best wishes for your progress, I'll watch with interest.
