Had to go to a meeting at Hangar lane today. After white city the
train just took off, we must've been doing 40-50 mph. How come the
other tube lines are so slow in comparison? The piccadilly plods its
way to acton town and the northern line between east finchley and
finchley central seemed to barely get above 25mph the few times I did
it last year. Why is the central line different?

I guess it's to do with what's allowed with automatic operation.

Any higher speed was mitigated for years by the fact that the
operators seemed to take about thirty seconds to release the doors at
every station. They seem to have got better at it now.

The announcements are still way off sometimes. Half way out the station and
they are still saying what station it is.

The Victoria line is pretty fast too, for the same reason

Trains on Piccadilly line seem to do pretty well speedwise between
Hammersmith and Acton Town.

And what about trains running fast on the Metropolitan Line? I heard that
the A62s could do close to 70 miles before they started to discover cracks
in the bogies.

What's up with the S stock, BTW? 'Any models running around for testing yet?

It is not, it just makes a lot of noise. I was shocked to discover the
leisurely Gospel Oak to Barking line does a similar length journey in
the same time, with only slightly fewer stops.

They've only just started building the first couple of carriages:

Hmmm, I am unconvinced by the average speed over the whole line. The
Central and especially the Metropolitan line have long non-stop expanses
which would certainly help the overall speed, but not the speed in
central London with lots of stops.

But on reading the original post more carefully, it seems Boltar is
discussing the speed in nonstop areas so this is not relevant.

Many years ago when I was just starting with LT I had a run out to
Amersham. On the way back I got a cab ride and certainly saw 70 mph on
the speedometer. It was a bit "shake, rattle and roll" as well but great
fun.

For a different reason, I'd say. The Victoria Line doesn't follow the
lines of the streets above as much as earlier built tube lines so has a
higher maximum speed because it doesn't have the curvature.

92TS is the only tube stock on which every axle is motored, so probably
has better acceleration than other stocks.

The Met main line, late at night, is hardly known for its sluggishness. I've
been on post-midnight trains, many times, and been hanging on for dear life
to anything that was fixed, especially between Finchley Road and Moor Park!
