Mike, the turnback loops on the lower level look great, as does the little wooden train! Measure 4 times before cutting sounds good to me; on second thought maybe you should sleep on it after measuring, then measure all over again! 
I only know what a Tardis is because that is what Dr. Who uses to travel through time. I never heard of it until our older daughter and son-in-law started watching it when they were in college or maybe even high school. Then I found out recently that Dr. Who has been around since 1963! Who knew!!!
Very nice job on yours, Lee!!!
Bill, nice barrel loader. I had HO trains growing up, so I was unfamiliar with Lionel operating accessories. I have bought a few since moving to O gauge about 10 years ago.
Jeff, I agree the accessories do remind me of the electric football game. My aunt and uncle bought one for my brother and me for Christmas one year. We got frustrated that you had to line up all the players with the little plastic tabs just right underneath for them to go where you wanted them to. We reverted to the table hockey game with the long metal rods you moved to control each player. We literally wore that thing out over the years.
Here is a photograph of my Atlas switch tower I built recently while recovering from back surgery. I may place it elsewhere on the layout, but off hand it seems at the entrance to the little yard is the place. That's about all I have accomplished on the layout since May 24th, surgery day.
