How did the London Underground get
nicknamed 'The Tube'?
Why did the underground frighten horses?
What is the origin of the announcement: "Mind the
gap"?
In this, the third post on my exploration
of the area around Bank station, London, I focus on some startling facts about the
history of the underground.
Mind the Gap.
My day out in London started at Bank tube station. What
surprised me as I emerged up onto street level was the amazing historic
buildings within sight of the station: The Bank of England, The Royal
Exchange and the Mansion House. Apparently the Victorian engineers were also
overawed, and afraid of being sued by wealthy property owners if their
tunnels caused subsidence.

Their solution was the divert the route of
the tunnels to avoid going directly beneath these important buildings. This
meant around Bank, there are some of the sharpest bends in the tube network, and some
speculate that one particular sharp turn was to avoid tunnelling
through the Bank of England's vaults. All this meant that long curved platforms
were necessary, which led to substantial gaps in places between platform
and carriages. It is because of this that often repeated public announcement,
"Mind the gap" first came into being.

Bringing the House down.
Work on the tube network began in 1860 and
the stretch of the Metropolitan line between Paddington and Farringdon, was
opened on 9 January 1863 to become the world's first underground railway.
To minimise costs and because no one had
ever undertaken such a thing before, the initial method of construction was to
dig a deep trench, lay down the track, then build a brick arch over it to form a tunnel
and then cover everything over. This worked well when the proposed route lay parallel
to road, but between Paddington and Bayswater, houses were orientated the
wrong way, at ninety degrees to the direction of the track. In addition, on Leinster Gardens, two grand houses stood in the
path of excavations.

The solution was to demolish the houses to
allow excavation of the tunnel, then rebuild the facades to conceal the hole
behind, which as left open, to allow the train drivers to vent their engines
steam - much to the alarm of horses passing by on the road.

Because the system was built as cheaply as
possible, rather than design new locomotives, pre-existing steam engines were
used. Of course, the underground tunnels soon filled with thick coal smoke, as
The Times commented:
"A
journey from King's Cross to Baker
Street is a form of torture which no person would
undergo if he could conveniently help it."
In counter-attack the underground's
marketing people quickly came up with a story that the smoky atmosphere was
actually beneficial to asthmatics! But this propaganda didn't convince the
train drivers who grew thick beards to try and filter out the soot. Eventually,
common sense prevailed and the engines were modified so the exhaust could be
collected and vented in a big blast when the trains passed close to the
surface.

The Tower subway carriage of 'Tube'-
Claustrophobic, hot, gloomy and smelly. |
The Tube under the Thames.
In 1870 the first deep level stretch of the
underground was dug between Tower Hill and Tooley Street and passed under the Thames. Because there was no way to ventilate the tunnel as it ran
under the river, and so rather than use steam engines, a special windowless carriage
was developed, hauled through this section by a cable. This became known as
'The Tube' - a name which stuck for the rest of the network.
The section of the network was, by all accounts, not a good place for a claustrophobe to
visit as recorded by Charles Dickens, jr:
"..there is not much head-room
left, and it is not advisable for any but the very briefest of Her Majesty's
lieges to attempt the passage in high-heeled boots, or with a hat to which he
attaches any particular value."
Traversing this section sounds deeply
unpleasant: the tube was hot, humid, the cable mechanism very noisy, the
travelling compartment windowless with gloomy gas-lights and to top it all -
the carriage frequently got jammed in a dip in the middle of the route. After
just three months the train was scrapped and the tunnel converted to pedestrian
use.
I went down
and down between two dingy walls until I found myself at the round opening of
the gigantic iron tube, which seems to undulate like a great intestine in the
enormous belly of the river.

The Second Tunnel under the Thames.
James Henry Greathead along with another
engineer, Peter Barlow, developed a device that successfully drilled much
larger bore tunnels. Their device consisted of an iron cylinder, just over 7 ft
in diameter, fitted with screw jacks that allowed it to be inched forward. As
the labourers excavated beneath the safety of the shield, so the device was
advanced and a permanent lining of cast iron segments fitted in place behind
them. Over time Greathead refined the device to include the use of compressed
air and hydraulic jacks, which are now standard features of tunnel
construction.

cat biscuits at the end of it?"

And finally, a Victorian wonder the underground system may have been, but sometimes it seems as though it's still stuck in Victorian times - with the heat, congestion and general state of decay. What are your impressions of the underground: a system to be proud of or something to be tolerated?
