i think the central is fastest tube, also it may be the fastest line at
100kph (62mph) towards epping and ruislip

Which line do trains travel fastest and how fast do they go? Any
difference in sub surface and deep tube lines? Anybody got info on
what speed trains travel at on all lines?

Fastest surface: Metropolitan
Fastest tube line: Piccadilly on the Hammersmith - Acton run.
Speeds: Not sure there... anyone?

Can't find the info at present, but IIRC the A60/A62 stock on the Met is
allowed up to 60 mph. The speed limit on the Piccadilly is 45 mph, and I
thought some other tube lines were faster. (Jubilee 50 mph?)

They get up to that speed in passenger service? I wouldn't really know, as I
haven't been as far Epping on 92TS. Last time I went that far was on the old
62 stock.

Wouldn't surprise me if they do approach that speed. There's a portion of
the Central Line between Leyton and Leytonstone where the track runs
parallel to the A12, which is a 3-lane dual-carriageway with a 50mph limit
at that point. The trains usually run at about the same speed as, or
sometimes a little faster than, the middle-lane traffic, which is probably
sitting at about the 50mph limit.

The best way to measure the speed is get a good GPS receiver - although its
use is obviously limited to surface sections. AFAIK the Picadilly line 1973
stock has a top speed of 45 mph. 60 mph on A60/62 Metropolitan line stock is
only achievable west of Harrow on the Hill.

Presumably these stats all relate to surface sections. It would be
interesting to learn what the highest/average speeds are in the tunnelled
sections.

Obvious constraints are the frequency of station stops, gradients and
curves - I would have thought the average speed was probably around 30 mph
or less.

Also in the case of 'tube' lines there must also be issues relating to air
pressure and resistance, the train is after all acting rather like the
piston in a bicycle pump. As a child I recall rather uncomfortable 'ear
popping' on the Northern Line section between Kennington and Waterloo.

Which is about 60 miles an hour or a little more.

The Piccadilly Line has a line speed (the maximum speed allowed on the line)
of 45mph, the '73 tube stock is capable of exceeding this by quite a bit.
I've had a non-refurb totally off the clock (it went up to just over 60mph).
Of course this dosn't take account for any inaccuracy on the speedo, and as
the re-furbs are about 2 tons heavier they're probably a bit slower.

I tried to do this on the Met line the other day, but couldn't seem to
get sufficiently good GPS reception (yes, this was in the surface
sections).

I've also tried doing the same on the SWT Reading line, which seems to
work well on the Junipers, but not very well at all on the 455s and
421s/423s, for some reason.

Perhaps there are GPS receivers with better sensitivity than my basic
eTrex, though?
