Murad Qureshi calls for new signal box - 1928 equipment causing
commuter misery at Edgware Road Tube

Published: 4 June 2010 by JAMIE WELHAM IT has been described as the
“arm-pit” of the underground and is a perennial source of rage for
browbeaten Circle line commuters.

The older equipment often works better than the newer kit though! The
east end of the Piccadilly is a prime example! (as for the new
signalling on the Jubilee)

"When there was only one line for the whole of London" What can that
refer to? Neither telephones nor rail lines makes much sense in this
context.

Use your imagination Marvin!

Life's bad enough as it is - why invent any more of it.

Indeed.

The whole sentence is "At its nerve centre is a signal box first
fitted in 1928 – a relic from the first days of the network when
there was only one line for the whole of London."

I suspect that it is just bad journalism, mixing up things the
journalist was told. As background the journalist may have been told
that at one time Edgware Road was on the only underground railway
line [1] not just in London but in the world. However, that was a
long time before 1928.

The photograph shows a miniature lever frame box typical of the era,
particularly in London and SE England. If it has been well
maintained the lever frame should work well, though if the
components on the track are of the same era some may be giving
rather more trouble, though fish tank relays tend to be pretty
indestructible.


[1] in the sense of a railway running under city streets for an
extended distance with intermediate stations. There were earlier
underground railways, including the Liverpool and Manchester Railway
tunnels in Liverpool

Hang on, so that levery pipe-organ thing the guy in the photo is playing
is from 1928? I assumed the story meant the signal box was built in 1928,
not necessarily that all the equipment in it was still original. But i
know nothing of these things.

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!

The lever frame might be from the 1920s but there has been no
confirmation yet whether the faults lie in there or in the electrical
gubbins elsewhere into which it is plumbed and which could be of
rather more recent origin.

The only other work that has been done is rewiring and the electrical
kit such as relays. Many of these are refurbished by LU REW. Then
there's things like speed control relays that were put in after
Moorgate crash (mostly), but I don't know of any big failures there/

What has failed a fair few times is the new electric points at Praed
Street!
