I've been looking for a comprehensive book or books that document the Lionel accessories since 1970. I recently saw a video of the rotating coal tipple (and had no idea it existed). I am wondering what else was released while i was not paying attention to trains?
The closest I have found is Lionel Accessories at Work on Toy Train Layouts by Neil Besougloff. It was published in 2000 so wouldn't include the last 20 years, and from the description I am not certain it includes a comprehensive list, so much as ideas for how to work accessories into your layout.
As reference, I am looking for something like the old Greenberg books such as Greenberg's Guide to Lionel Trains 1901-1942 Volume III Accessories, or Greenberg's Guide to Lionel Trains 1945-1969 Volume VI Accessories
