Default Jubilee Line - noise and maps

How come the Jubilee Line is so noisy? It seems to be considerably
noisier (from inside the trains, though also from the platform when a
train approaches/leaves) than the other lines.

Does it actually run faster, or is something else causing the noise?

Also, what's with the line map above the windows? East/west seems to be
reversed depending on which side of the car you're sitting on.
Presumably this is to make it consistent with the direction the train is
travelling in, but since (AFAICT) other lines don't do it that way, I
just found it confusing...

If you mean the whining noise as a train accelerates or decelerates, that's
because the trains on the Jubilee (1996 stock) use Gate Turn-Off Thyristors
to control the supply of electric current to the traction motors, the system
being very similar to Connex's Class 465/466 Networker trains which make a
similar noise. (Info from Richard Griffin's web site at
http://www.squarewheels.org.uk/rly/s...tubeStock.html )

It's supposed to make it easier to comprehend, since the layout matches the
direction of the train. Personally I find it confusing too. Anyone who's
ever looked at a map of the South Bank area knows that Waterloo is to the
left of London Bridge, so it's not helpful (to me anyway) to show it the
other way round.

It's only possible for lines where the trains never get turned round and
where all the line diagrams are on the sides of the cars. I think that's
the Jubilee, Victoria, Bakerloo and Waterloo & City. Not sure if the maps
on all four lines are arranged like this. Jubilee and Victoria definitely
are.

Thanks! There seems to be more noise while travelling through the
tunnels as well, though, at least compared to the lines I usually travel
on (Picc, Northern, sometimes Central and District)...

Line maps on the Waterloo & City are pretty pointless though

I think that they're directional, but I don't travel on that line
often.
