I spotted a film about the OH R a few days ago after watching a video about London Trams where a Heinkel Kabine appears briefly. Had not heard of the OHR before, great structure! A similar thing in New York (part of the old "El") is now a public park. The OHR video gave me a link to this, and I was watching it while packing some Adders into mailing boxes, and spotted the 3Wlr at the end. I like, cars, planes, ships, buses, trams, trains!
Oh, not living serpents, my latest percussion invention!
