4 or 5 running in evening peak on Tuesday (3 July) including fast Aldgate
to Amersham. But not as fast as I think I remember they used to go.

No, the top speed was reduced significantly after the bogies starting
cracking. The new S stock has a higher top speed than the reduced A
stock speed, but still lower than the original A stock speed.

They seemed to be moving at close to 60 miles between Chalfont & Latimer
and Chorleywood.

They were certainly moving faster than A stocks between
Harrow-on-the-Hill and Finchley Road.

What are the speeds on some parts of the Central Line's outer extremes?
It certainly felt faster than 35 or 40 miles.

85 km/h, down from 100 km/h since Chancery Lane bogie incident.

Those are the speeds in ATO, apparently rumours suggest can be exceed
in CM.

1992 stock is being rebogied ... methinks they must be a very long way
into that project now ... the original Kawasaki bogies are replaced by
new Siemens bogies ... I have no idea either way if 100 km/h will be
reinstated or not.

Don't forget though stock speed is academic as Central Line ATO uses a
speed control system where maximum safe speed for present section and
target speed for next section are commanded from trackside to train.

Read on Wikipedia that Saturday was the A stock's last day of revenue

I thought that they were going to keep a few around for nostaglia runs,
similar to the 38s or to the Sarah Siddons.

I rode on an A stock last Monday and I saw one call at Aldgate today.
