They did. As far as I'm aware humans haven't significantly changed
physically
for the last few million years. Unless you know otherwise.

If that exciting new technology is smaller, wouldn't it be nice if
some of that space was in the passenger area, rather than being an
empty, useless, void?

I was under the impression that that is exactly what is happening with the
new 2009 stock. Smaller wheels (740mm diameter), resulting in more space in
the passenger saloon. There is an extensive article in the July "Modern

Doubtful. The wheels are under the seats so how will smaller wheels
make
more room? You can't lower the floors because of the platforms. More
likely
they'll use up the free'd space with equipment under the seats.

I'm afraid it bewilders me why in britain we constantly have to
re-invent the
wheel. Not just on the tube but look at all the different designs of
stock on
the mainline railways , especially southern region , even when said
stock
is doing the same job. The amount of money wasted on pointless
redesigns
must be staggering. Designs of aircraft can stay in production for
decades,
for trains its a new design each year almost. Whats so special about
trains?
Nothing as far as I can see other than various management teams wanting
to make their mark while they're in the job.

The obvious solution would be electro-magnets, energised by a switch. Once
someone gets up and the seat returns to the upright position it stays there

someone else takes over the seat but it wouldn't last for long (especially
at terminii!).

Problematic for people with pacemakers though.

People have got taller, and have bigger posteriors, than in recent
history. The changes are big enough to be of concern to seat makers
and train designers.

Well they did. Or at least they ordered an update of the 1996 stock
which
became the 95 stock.

10 years ago, which is Actually Quite A Long Time (although if you were
being especially pedantic, you could point out that LU/Tube Lines
bought a reasonable quantity of new 1996 stock that was delivered last
year...)

also seem to imagine that Alstom would sell some to Metronet at a decent

If they earn money from it yes they would. In business money is money

Sort of, but companies are often wary of selling to (and especially
sharing IP rights with) their biggest competitors, because this raises
issues that go beyond the profit on the individual sale.

Well, I believe I've seen the British public get significantly more
obese in the 6 years i've been living here -- me included unfortunately.

The change in Japanese physique, especially, due to the improvements
in nutrition since WWII are rather impressive.

As you perhaps know, both Londoners and tourists are taller and
weightier than in 1938.

I'm not sure that this explains why the seats keep getting smaller
though.

In any case, the change in average size of person since 1938 must be
trivial in comparison with the range of actual sizes either then or now.

The average tube passenger has probably shrunk since the 1930s, along with
changing their sex.

What lines are getting the 2009 stock?
