Uh huh. And? The articles appeared within a couple of weeks of each
other in the same magazine.

I've not seen these, but I remember an "Eagle" centerfold (...) showing
a exploded diagram of a flywheel locomotive shunting engine, with the
flywheel running in a vacuum (or was it helium) enclosure.  The yard
installation had trackside posts where the engine stopped to pick-up
electricity to spin up the flywheel again.  Never saw one in real life
though...  All I can see is it avoided the necessity for installing a
continuous electicity supply to the engine - which is probably why it
wasn't a commercial success?

Swiss railways tried at least one of these. They had over-capacity in
overhead electricity supply (hydro powered), but the cost of wiring an
entire marshalling yard was excessive. The flywheel shunter charged up
whenever it hit the wires at the head of the yard again.

The Swiss overhead power investment was so large that during WW2 they
even converted a few steam locos to use giant immersion heaters. Coal
was in short supply, as was capacity to build new electric locos.

My memory has stirred a little on this. I still can't find an on-line
source, but I do note that the London Transport Museum features cutaways
and covers from "Modern Wonder" there's a cover about a trolley bus on
their site. Modern Wonder pre-dated Eagle by about 20 years and had
similar content, a mix of stories, technology news and cutaway drawings.

From what I can recall about the article, the bus in question used the
flywheel, which was brought up to speed mechanically, to store energy
while slowing down and used the flywheel when setting off to save
energy. It wasn't AFAIR capable of moving far using the flywheel as a
source of power. It was, at best, the use of a flywheel to perform the
same function as the battery in current hybrid vehicles.

Tsk!  How are we going to achieve anything if people are so negative.  Thats
only 1.6 million 1 kg bags bags of flour.  All you need to do is build such
systems next to large bakeries and you have solved two problems in one e.g.
energy & storage.
