Blucher in 1814 was the first steam locomotive operating on flanged wheels on metal rails. |
On
July 25, 1814 George Stephenson put his first Steam locomotive, a small engine
for use hauling coal
on the Killingworth Wagonway in England near his home and workshop.
He called the noisy little contraption
Blucher after Prussian general
Gebhard Leberecht von Blücher who
had helped the Duke of Wellington whip
Napoleon. It could haul 30 tons of coal up a hill at
4 mph and was the first successful flanged-wheel
adhesion locomotive—gaining traction
only from the wheel turning against the rail and not from a cog
or other system.
Steam had been applied to moving coal as early as 1804 by
Richard Trevithick at a colliery
at nearby Tyneside and several
other engines were built by various men for mines in the Newcastle area. But none
worked so well, so reliably, and so safely—boiler
explosions were common—as did Stephenson’s.
The Blücher is now
considered the first truly modern steam locomotive and Stephenson the father of
an industry.
Stephenson was born on June 9,
1781 at Wylam, Northumberland. His father was a fireman on a steam pumping
engine in a local colliery and his son entered the mines in the same
capacity at the age 17. Although he had
no formal education, he took to the mechanics of the crude engines and
began to study at night to improve his condition. He worked at various capacities in the mines,
married, had children, and was left a widower.
When he repaired a broken
engine at Killingsworth in 1811 he was promoted to engine wright and was soon repairing—and improving—pump and winch engines for several pits in the
area. After the successful introduction
of the Blucher, Stephenson is
believed to have completed 16 other engines of various design. Not all worked. At least two had to be withdrawn from service
because of defects. But with every
experiment and every engine built, Stephenson learned.
His new engines were too heavy
to operate on traditional wooden rails,
attached strips of iron were not durable, and solid cast iron rails were too brittle. So Stephenson improved the cast iron rails
and went to the practice of multiple
wheels to better distribute the engines’ weight.

In 1820 be built an 8 mile long railway from Hetton colliery to Sunderland. Gravity was used on the down slope, but the steam engine provided
power on the level and upgrade. It was the first longer railroad employing no
animal power at all.
In 1825 he was hired by Edward Pease to construct the 25 mile long Stockton and Darlington Railway to bring coal from the mines for
market. Pease also joined in forming the
company of Robert Stephenson and Company
to manufacture new, more powerful engines for the railroad. The company built four engines, Locomotion, Hope, Diligence,
and Black
Diamond. On September 25, 1825
the new line opened with Locomotion hauling 80 tons of coal and a specially built car for dignitaries, Experiment, the first ever built specifically for
passengers. The dignitaries found
themselves hurtling along at an astonishing of 24 miles per hour in one
stretch. The road was built with wrought
iron rails with a track gage of 4 feet
8½ inches, which became the standard in the British Empire, the United
States, and most of the world.
Stephenson was soon also at work laying out the new Liverpool and Manchester Railway, the
first line to connect major cities
at some distance and to contemplate regular
passenger service.
He employed now accepted techniques like using grading, cut backs and trestles
to keep the road bed as level as possible, and crossing a bog
by literally floating the track—something
of an engineering marvel. But he was not
assured the contract to build locomotives for the line. Instead the railroad directors announced a
completion.
Rocket, the first locomotive to operate on a rail line connecting cities at some distance. |
Stephenson’s entry was Rocket, largely designed by his son Robert and the first to use the
recent French innovation of a fire tube boiler. The trial required engines to run 60 miles
and weigh no more than 6 tons. Rocket
easily won the competition and Stephenson was a famous man overnight. The railroad opened on September 30, 1830
with a raft of dignitaries led by the Duke of Wellington on hand. A parade of trains powered by Stephenson
built engines left Liverpool with open passenger cars. The engines included Northumbrian driven by
George Stephenson, Phoenix driven by Robert, North Star driven by his brother, and
Rocket.
The day was somewhat marred
when a Member of Parliament foolishly dashed in front of
Rocket and was crushed to death.
Stephenson went on to a lauded and distinguished career
both as a civil engineer laying out
new lines and as the manufacturer of ever more powerful and efficient
engines. His son Robert and others
contributed to the success of the company.
The first engines used commercially in America were built at Stephenson’s
shops and American designers learned their craft there.
Stephenson died on August 12, 1848 at his home in Chesterfield, Derbyshire a wealthy and
honored man. But despite his
contributions to British wealth and power, because of his humble origins he was
never extended a Knighthood.
