Thank you, Andy, Steve, Jeff, T-Bone!
Andy, it is fun to see a layout or layout plan develop. I am following several at all times.
Steve, It does make sense to move the tunnel portal. I had noticed the supports on the track but had no idea how to remove them. Thank you for your input!
Jeff, SCARM is intuitive, but I lose it on some things. Having a very slow computer makes it almost impossible to get the flex track where I want it and do the snip. I totally forgot how to do the snapshot, but found it for the 3D view, but not the track plan view.
T-Bone1214, Trials and tribulations is an excellent way of putting it!! 
I'm glad following this thread has helped you through places you were stuck! I was stuck in the very beginning, before I started this thread the first week of January 2017. I don't want to think where I would be if it wasn't for all the help from so many great forum members! I'm glad you are getting ready to move on past painting your background. Yours is one of those planning threads I was thinking of above.
