Update: More progress!  This is the basic track layout.  I will have yard limit signs on the loop as a challenge and I have crossovers to go on the long straight stretch to connect to the club layout for larger shows. So Ive built the lower frames of all the cars just to see spacing of the decouplers.   Still need to finish both tankers and both gondola cars.  The boxcars are waiting on roofs and the flat cars waiting on sides. Here is a quick video.  I did not video me testing cars through the switches but it pulls/pushes 3-4 no problem.  I had no issue pulling the whole consist but could not push it into the sidings so I will have them sort the cars into the sidings.  Theres actually alot of wheel hop and spin right before it derails at the switch. The track is elevated 4 plates in both of these.  If the puzzle goes over well I want to ballast and install tiles for ties
