Jacq Damen's legendary Dreimühlentalbahn. Jacq set up the catenary without wires and yet it still looks realistic, which inspired me to do "wireless" catenary on the Poggenbahn. Here's a wonderful video made by Vikas Chandar. Jacq was interviewed by Hagen von Ortloff on Eisenbahn Romantik in January 2010, and you can watch the video here. Unfortunately Jacq passed away in January 2020. The last I heard, his layout was sold and is in storage somewhere in Sweden. I'm hoping it will find a happy home and will continue operations soon.
