Larry,
I built a tilting train about 4 years ago but that was based loosely on the
4559. It used the same principles (slanted truck pivots) with tune-able lean
angles and could snake through S-bends at reasonable speeds. Only reason I broke
it up was because it had done the rounds and I wanted to build something else.
Something more substantial like the bevel-gear approach is necessary in any case
with models the size and weight of Mark's. I've seen his Pendolino in action and
although the angle of lean is quite moderate, it stays together quite well! With
the lighter 6-wide bodies I found it best to use a single common truck (bogie)
between the coaches and built in a simple .'master and slave' leaning mechanism
to prevent violent or impossible movements when the bogies pointed at
contradicting angles of rotation.
Might have an old pic somewhere

I am 80% sure (but not 100%) it was either E. Brok or J. Mathis. (20 years ago, 30-Mar-04, to lugnet.trains, lugnet.loc.uk)
