Somewhere back I recall starting the layout about this time in 2012; well last night we finished laying the track for the upper double loop. I had ordered a custom 30* crossing from BKO---they were easy to deal with and seem to offer both a wide range of product at a high quality level--imagine that!

Well, thanks to all the wonderful time and help from Dean, Manfred, Michael and Dick---we are making progress and should have the loops wired prior to thanksgiving!
Enjoy--
