Thank you,Commenter, for that greatly interesting article. However, the docplayer.net presentation was too small for me to comfortably read, so I went digging via [Arnd Meyer, Erlangen. Wheel sets or independently rotating wheels from theory to practice] [www.google.com] and found this pdf version -- [assets.new.siemens.com] -- that can be adjusted to be quite easy to read. The traditional type of AP railfan may find other articles of interest via that gsearch link -- [www.google.com]
