I thought that A stock cannot run over entire Inner Circle?
HI Guys

The restriction used to be on the western part of the Circle (Praed Street
Jcn to High St Ken. IIRC) where A stock was only allowed to run empty and
there were severe restrictions on what it could pass on the opposite road
(e.g. A stock was banned from passing another A stock),. AIUI was virtually
impossible to timetable a move in normal traffic. It was supposedly a
combination of length, static width (Loading Gauge problems), end overthrow
and dynamic envelope.

I don't know if the restrictions are still in place, but am not aware
(cannot remember) of any major work which would have alleviated the problem.

Thanks for correcting me on A Stock width restrictions!
So there are no immediate plans for the spare stock then?! (Oh and yes
I am painfully aware the A60s are due to go soon, a shame as they are
still a great piece of kit)

A stock cars are 137 mm longer than C stock driving cars and 1227 mm
longer than C stock trailer cars. They are 26 mm wider and pretty well
the same height.

If the air metacone suspension had survived the C stock refurbishment I
would expect more dynamic envelope issues there than with A stock. Brian
Hardy says it was replaced by a rubber blob system like on the D stock so
maybe that won't be an issue now.

By the time it is withdrawn, much of the A stock will be 50 years old, a
recent record in London.

AIUI two 4-car units of A60 are to be stood down immediately following
end of EL line.

One unit will be used as a spare parts donor for the rest of the
fleet. One unit will be permanently formed as a sandite unit - I don't
know how many cars used in this. Nor do I know any of the car numbers
of either unit.
