The Transcontinental Railroad: Challenges and Innovations

The transcontinental railroad, stretching 1,776 miles, from Omaha, Nebraska, to Sacramento, California, was America's greatest 19th-century achievement. It revolutionized communication, united the nation's eastern and western halves, and expedited both transportation and commerce.

What had been an arduous journey of four to sixth months by stagecoach or a couple of months by ship, requiring the crossing of Panama (there was no canal until 1914), which offered the danger of contracting malaria, was cut to a mere two weeks, and the cost of travel was reduced by 90 percent!1

However, to complete the railroad, both the Pacific Central Railroad (PCRR), which built the railroad from the San Francisco, California, eastward, and its partner and rival, the Union Pacific Railroad (UPRR), which built the railroad from the Omaha, Nebraska, westward2, had to overcome major obstacles. The terrain and weather were the PCRR's major obstacles, while personnel were the UPRR's greatest impediment.

To advance westward, a trestle or a bridge had to be built for every river and gorge. To construct a bridge over a river, workers used a steam-powered pile-driver, which drove posts of wood into the bottom of the river to support the bridges.3

But the Sierra Nevada Mountains, between California and northern Nevada, represented the greatest obstacle to PCRR's engineers. Using black powder and hammers and chisels, Chinese workers and others had to blast and carve ledges out of the sheer cliffs and precipitous rock faces so track could be laid for trains. Cape Horn is an example of the tremendous challenge these mountains posed.4

Another impediment the PCRR had to overcome was “a cemented gravel hill” in the Sierra Nevada foothills near Bloomer Ranch. Engineer Theodore Judah's solution to the problem was to cut a “wedge” through the hill.”5 The project, known as Bloomer's Cut, produced an 800-foot-long channel that is 63-feet-deep at its greatest depth.6
In addition, the PCRR had to blast 15 tunnels through the mountains.7

To blast the rock in the Sierra Nevada Mountains, workers on ropes were lowered down cliffs. Dangling, they pounded sharpened rods of iron into the rock with hammers, stuffed the holes with black powder, set fuses, and shouted to be hauled up. Instead of ropes, Chinese workers used reed baskets. The work was dangerous, resulting in many workers' deaths.8

The Summit Tunnel indicates the magnitude of this requirement:

In the spring of 1868, the Sierra Nevada were finally "conquered" by the Central Pacific Railroad . . . after almost three years of sustained construction effort by mainly Chinese laborers, with the successful completion at Donner Pass of its 1,659-foot. . . Tunnel #6 and associated grade, thus permitting the establishment of commercial transportation en masse of passengers and freight over the Sierra for the first time. Following a route first surveyed and proposed by CPRR's original Chief Engineer, Theodore D. Judah (1826–1863), the construction of the four tunnels, several miles of snowsheds and two Chinese Walls necessary to breach Donner Summit constituted the most difficult engineering and construction challenge of the original Sacramento-Ogden CPRR route.9

Tunneling was a time-consuming and dangerous undertaking. Workers averaged about one-foot of progress per day by drilling and packing holes with black powder, connecting and lighting fuses, and running from the tunnels. The replacement of black powder with dynamite doubled the daily average obtained from blasting. Even so, it took from August 1866 to November 1867 to create the 1,500-foot Summit Tunnel.10

Blizzards caused avalanches, which often destroyed trestles and killed workers. Snow sheds were built to protect tracks and workers. Thirty-seven miles of snowsheds were built from 1867 to 1869.11

This tent city became Cheyenne, Wyoming. 

Although the UPRR had a chronic shortage of employees early on, this problem was largely solved by Irish immigrants and Civil War veterans, both of whom needed work desperately. After the U. S. government threatened to eliminate the UPRR's funding in 1865 because of the company's lack or progress, UPRR increased its speed, laying two to three miles of track each day. Workers built way stations every 100 miles, giving rise, in many cases to temporary towns providing saloons, dance halls, gambling houses, and brothels in which workers could spend their money on their Saturday nights off. Called a “Hell on Wheels,” such a town often followed the tracks, moving as workers moved.12 However, a few of these towns became permanent cities, including North Platte, Nebraska, Julesburg, Colorado, Cheyenne, Wyoming, and Medicine Bow, Wyoming.13

Once the railroad got past the Sierra Nevada Mountains and the Rocky Mountains, the employees' work was easier—relatively easier, that is. But, as we'll see in the next post, the greed and dishonesty of one of the railroad company's top executive officer created other problems.
