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?

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!
