the direction of the PCC trolley group at Yahoo which very recently
has been having a heated debate over why all our US LRVs don't give as
smooth and untroubled a ride as PCCs, even with their technological
sophistication. (And I may say I don't really agree with that
assessment, although it may be that there are engineering problems
etc. which tell against the metalastik susoension either in
maintenance, ride, design, you name it. The engineers will know and
that group has some of the best in its cadre of correspondents.
Not that those who claim the PCC gives a better ride are suggesting
its ride was 100% perfect, far from it.
But anyway, I urge you to join that group, read what they have to say
and then give all of us your opinion because I suspect it's my
ignorance of modern truck technlogy that prevents me from giving a
credible answer to your question.

You trying for a PhD on old tram trucks, Andrew?
The M&T 588 sounds like a useful design.
When they transport revolution is here and we need thousands and
of single truck trams we'll know what to go for.:)riding) tram
Has there ever been a successful (in this case that means good
with metalastik suspension in your estimation? (Don't even thinkabout
nominating Melbourne's Z-1s). The lack of metal on metal contact andNo, no Phd, just been fascinated by tramcar trucks since I were nobbut
implications for almost maintenance free operation make the idea
interesting.
