With all the wonderful inovations and inventions that happen here I didn't
realize or remember the order in which these things happen. Thanks for the
recognition and the iteration.
Along these lines I was thinking about an area on the web (a.k.a a web site)
that tracks LEGO train (and/or other theme) inovations. For instance:
couplers, motorized switch tracks, auto decouplers... The site author would
(with the permision of the inventor) create a write up with pictures tracing
the various solutions and history of a particular area of inovation.
There are so many web sites that can be dedicated to LEGO... and books that
could be written but color publishing is so expensive and both very time
consuming.
