yea I did it looked good on paper but in construction it limited the running of trains. so far this layout has been 500 more in track but haven't had to buy a single switch I have had enough switches only piece I haven't been able to incorporate is a 45 degree x here's the track plan as of now. also need to figure in 4 bridges 2 truss and 2 under arch. and need to add a ground plane to one area its where the engine stopped on the lower level didn't have an issue until I ran power to the upper level.
