Ron - your conversion looks great -- the blue rail folks seemed to have disappeared for a while after releasing their first board (which, I believe, is no longer available). But it looks like they are back (or maybe they never went away I just lost track...). I had considered trying out a BR board for one of my Flyer locos (without going to battery power) but about the time I was going to try it out, it seemed like I couldn't find the BR board. So maybe I should put this back on my list. I assume that the board, anyway, would fit inside S-gauge locos.
One advantage for going to battery power for you Lionel/etc. types is you can now get rid of that pesky third rail
