being introduced on the Piccadilly, and moving over to replace the
rest of the 1938 stock (and the 1972 mark 2 stock eventually).

And my memory, FWIW, is that the 73 stock was introduced in about 1975,
not 1973.

Since tube stock seems to be good for at least 40 years' service, I don't
suppose the world would end if they delayed replacing the 73 for 5 years
(from now).

Yes it was. And the 1972 mark 2 first introduced in late 1973 (and
all in service by some time in 1974 according to a source I found
since).

A stock still going strong and will be very sadly missed. I sometimes
hear normals talking about the nice, comfortable train they caught
between Kings Cross and Baker Street or wherever. It's not just an
enthusiast thing.

LU stock seemed a lot more interchangeable then, swapping between
lines quite often. Nowadays it seems as if it's always purpose built
for a specific line and signalling system.

"Then" was before the A stock, however. It's never gone anywhere other
than the lines on which the stock it replaced ran, the Met and East London.

It happened not to, but much of its contemporaries did, and stuff since.

1959 stock ran on Central, Piccadilly, Northern and Bakerloo.

1972 stock ran on Northern, Bakerloo and Jubilee (some of them more
than once).

1973 stock only happened to run on the Piccadilly, so some have more
interesting histories than others.

1973 is more typical,like the A, C & D stock. It was the advent of the
1973 TS that allowed the cascade of the 1959 stock to the Northern. The
1962 stock, with minimal exceptions, never left the Central. The 1973 cars
are too ling to fit on other tube lines.
