Hold on, i've just looked at the link Nick posted. It's not from 1928 -
it's from 1926! Yikes!

Ther are others the saem

Hammersmith 1931

and other cabins like Rayners Lane, Harrow on Hill still manned power
frames.

*Almost* the entire underground except Central line and east end of
Jubilee (JLE) is on V-style remote control frames.

Hammersmith, Whitechapel, the Rickmansworth area or Rickmansworth
still have lever frames. Harrow has a push pull frame, with remote
IMRs. Rayners, the rest of Rickmansworth, Upminster, Barking, Amersham
are buttons that operate IMRs

Then of course most of the network still uses IMRs (Interlocking
Machine Rooms), remotely operated lever frames, except the Central,
new bits of the Jubilee and Terminal Five! Some of the frames are
ancient and have just been converted to IMR, even if it's operated
from a control room, by button or computer.
Then of course, there can't be train numbers with 8 or 9 on many lines!
