The Rise of the Modern City
PEOPLE MOVERS
Other U.S. cities were not without their innovative contri-
butions to twentieth-century urban progress. Almost 3,000
miles (4,800 km) from New York, cable cars were introduced
to San Francisco’s streets in 1873. Back East, hilly Pittsburgh
introduced its first cable cars during the 1870s, as well.
While horse-drawn streetcars, called omnibuses, had been
a common sight in the nation’s cities throughout the 1800s,
the first commercially viable electric streetcars went on line
in Richmond, Virginia, in 1888. A singular innovation made
this type of transportation system possible. That year a for-
mer naval engineer, Frank Sprague, created the system by
stringing overhead wires that produced an electrical current.
The result was the introduction of electrified trolleys that
could move along city streets at speeds of between 10 and 12
miles per hour (16 to 19 kmph), with some even reaching
speeds of 20 mph (32 kmph).
The technology caught on immediately. By the turn of the
century there were 30,000 trolley cars in use in the United
States, rolling along 15,000 miles (24,000 km) of track. By
1902, 97 percent of urban trolley lines had been electrified.
Such lines connected sprawling suburbs to the urban centers,
and even connected cities themselves, such as a trolley line
between New York and Boston, which opened in 1920. The
electric trolley became, notes historian James Kirby Martin,
“one of the most rapidly accepted innovations in the his-
tory of technology.” A British visitor to one U.S. metropolis
observed, notes historian Sam Halper: “The thoroughfares
are crowded, busy and bustling; and abounding signs of life
and energy in the people are everywhere apparent.”
Trolley systems, plus the handful of subway systems
around the country, meant that urban workers could now
live as far as 5 miles (8 km) from their work place and still
travel there in less than an hour. By the early 1890s such
