I learned a thing or two as well. Thanks for posting this info.
One thing I am not sure I understand:
"On my current layout, I use the magnet of the uncoupling tracks to indicate safe parking zones. If a train is covering the magnet, then it must be moved in order to allow another train safely pass on the turnout."
Maybe I am reading too much into this, but could you explain a little on this one?
Thanks again for the post
