I never thought of using molding, that's a great idea.
About how often do you have supports to prevent much sagging?
Fairly close as the moulding is quite flexible. I use 'L' brackets with the piece against the wall placed UP so that it is not visible below the shelf - the trains themselves obscure the bracket easily. You could also run some small quarter-round against the wall to add further support and use less brackets.
