It was the dawn of 1863,
and London’s not-yet-opened subway system,
the first of its kind in the world,
had the city in an uproar.
Digging a hole under the city and putting a railroad in it
seemed the stuff of dreams.
Pub drinkers scoffed at the idea
and a local minister accused the railway company of trying to break into hell.
Most people simply thought the project,
which cost more than 100 million dollars in today’s money,
would never work.
But it did.
On January 10, 1863,
30,000 people ventured underground to travel on the world’s first subway
on a four-mile stretch of line in London.
After three years of construction and a few setbacks,
the Metropolitan Railway was ready for business.
The city’s officials were much relieved.
They’d been desperate to find a way
to reduce the terrible congestion on the roads.
London, at the time the world’s largest and most prosperous city,
was in a permanent state of gridlock,
路上总是被推车 小贩 牛和行人给堵住了
with carts, costermongers, cows, and commuters jamming the roads.
It’d been a Victorian visionary, Charles Pearson,
who first thought of putting railways under the ground.
He’d lobbied for underground trains throughout the 1840s,
but opponents thought the idea was impractical
since the railroads at the time only had short tunnels under hills.
How could you get a railway through the center of a city?
The answer was a simple system called “cut and cover.”
Workers had to dig a huge trench,
construct a tunnel out of brick archways,
and then refill the hole over the newly built tunnel.
Because this was disruptive and
required the demolition of buildings above the tunnels,
most of the line went under existing roads.
Of course, there were accidents.
On one occasion, a heavy rainstorm flooded the nearby sewers
and burst through the excavation,
delaying the project by several months.
But as soon as the Metropolitan Railway opened,
Londoners rushed in to ride the new trains.
The Metropolitan quickly becamea vital part of London’s transport system.
Additional lines were soon built,
and new suburbs grew around the stations.
Big department stores opened next to the railroad,
and the railway company even created attractions,
like a 30-story Ferris wheel in Earls Court
to bring in tourists by train.
Within 30 years, London’s subway system covered 80 kilometers,
with lines in the center of town running in tunnels,
and suburban trains operating on the surface, often on embankments.
But London was still growing,
and everyone wanted to be connected to the system.
By the late 1880s,
the city had become too dense

with buildings, sewers, and electric cables
for the “cut and cover” technique,
so a new system had to be devised.
Using a machine called the Greathead Shield,
a team of just 12 workers could bore through the earth,
carving deep underground tunnels through the London clay.
These new lines, called tubes, were at varying depths,
but usually about 25 meters deeper than the “cut and cover” lines.
This meant their construction didn’t disturb the surface,
and it was possible to dig under buildings.
The first tube line, the City and South London,
opened in 1890 and proved so successful
that half a dozen more lines were built in the next 20 years.
This clever new technology was even used
to burrow several lines under London’s river, the Thames.
By the early 20th century,

Budapest, Berlin, Paris, and New York
had all built subways of their own.
And today, with more than 160 cities in 55 countries
using underground rails to combat congestion,
we can thank Charles Pearson and the Metropolitan Railway
for getting us started on the right track.
