We discussed this last year in the 'Rail & Rubber' topic.
It is good (but not surprising) to learn that the ultracapacitors have been
100% reliable after two and half years in the Mannheim tram.
Thanks for the link to the Railway Gazette article.
I remember the Rail + Rubber discussion and thought all of that stuff
would be helpful as follow-up, and of course though most of it is
internally-generated it does contain graphs and so on and also a
flywheel-solution (like the ones used by
http://www.parrypeoplemovers.com/)... and of course there are new people
on the list since then.
I am especially interested in the more visible solutions facilitated by
ultracaps including the ability to reduce catenary (overhead lines) and
allow engine-powered vehicles (trains and buses) to start from
platforms/bus stops with only electric power, with the engine off, in
order to reduce local emissions. The train concept is explained in the
Bombardier Mitrac document. There are some buses that use this in North
and an earlier development in Nuremburg, Germany
(http://en.vag.de/?pid=102) though I am not sure of the latter's current
