Most and Least Powerful LU Trains
 
Which LU lines have trains with the most and least "oomph" for want of a
technical expression (power-to-weight ratio?).

I haven't travelled on the Central Line recently, but supposedly with
Automatic Train Operation, the trains' acceleration is improved compared
with non-ATO operation. The Jubiliee line with their 1995 stock trains is in
my experience the quickest away from stops. Paris and Lille have very quick
metro trains and I believe they achieve acceleration rates up to 1.4 metres
per second per second so you really do have to hold on!

The Central Line's trains are the only ones on the Underground with all
axles motored.

As others have pointed out, the 1992 stock appears to be the fastest
accelerating. I would guess that the A stock has the worst acceleration, but
perhaps a higher top speed than other stock.

Presumably that would be for the rubber tyred trains only. Just out of
interest , is there a web site for the lille metro in english?
