I've always wondered what speed the Picc trains manage between Hammersmith
and Acton Town. They can move about in a very lively fashion (doesn't
matter if it is the current stock or the preceding stock). The prewar
stock seemed slightly less lively but that may be the memory of a ten year
old playing tricks. But, as for speed, I'm not sure they've ever gone
terribly fast (40mph?)

I had a cab ride on that section many many years ago and can recall it
being a tad bouncy on the second seat! Can't recall how fast we went.

On my very first day back with LU (having finished my degree) I do
recall an A Stock cab ride at 70 mph coming back in from a visit to
Amersham. Great fun.


I remember that they governed down speeds on the A stocks to about 50
miles, after discovering microcracks in the bogies.

Like I said, though, it has been my impression that the S8s do not move
slowly between Chalfont & Latimer and Ricky, as well as between Wembley
Park and Finchley Road.

Haven't had the pleasure of riding any fast trains out to Amersham, but
will do so soon.
