How have humans developed transportation to fit their surroundings?
1. To explain how the topography of Pennsylvania led to the building of the Allegheny Portage Railroad;
2. To describe the innovative technology used to build the railroad and explain how it was applied to other projects;
3. To compare the technology and level of success of the Pennsylvania Main Line of Public Works with contemporary transportation systems;
4. To discuss the effects of technological change and the future of transportation;
5. To investigate their area's transportation history.
Imagine riding on horseback or hiking through the Allegheny Mountains of western Pennsylvania in the summer of 1835. A dusty road climbs through an ever narrowing ravine. You are surrounded by steep hillsides covered with towering hemlocks, many reaching over 100 feet high. A small stream, barely four feet across, tumbles down its shallow and rocky course alongside the road. Here, high in the mountains, the air is cool, despite the season, and a feeling of wilderness pervades.
As you round a bend in the road you notice the sound of heavy machinery--wheels turning, engines cranking, ropes straining. You see a cloud of dark smoke belching from an unseen smokestack somewhere on the hillside to your right. Then, through a break in the trees, you glimpse the front section of a boat slowly moving up the steep slope of the mountain! There cannot possibly be a river or canal in such a location. What is more, the boat appears to be moving up a steep grade under its own power. Clearly, an unusual event in America’s transportation history is under way.
As the 19th century dawned, it became clear that the transportation problems facing the new United States were as enormous as its territory. Post roads ran along the Atlantic seaboard, but by the 1820s, it seemed everyone wanted to move west, beyond the coastal mountains. As these new lands were opened for settlement, the few roads penetrating the mountains became clogged with wagons and travelers on horseback and on foot. Railroads and canals would provide more efficient transport, but early railroads could not handle the steep slopes of the Allegheny Mountains. The Allegheny Portage Railroad, which consisted of a series of 10 inclined planes connected by level sections of track, provided an innovative solution to this problem. Stationary steam engines towed railroad cars up the first five inclines and lowered them down the remaining five. This railroad was part of a much larger system, the Pennsylvania Main Line of Public Works, built by the state of Pennsylvania to compete with the Erie Canal in New York.
Begun in 1826, the Main Line system consisted of sections of canal linked with sections of railroad. Eventually this system stretched nearly 400 miles to connect Philadelphia and Pittsburgh. Construction of the Allegheny Portage Railroad section of the Pennsylvania Main Line system began in 1831, and the railroad opened to traffic in 1834. For 20 years, the railroad hauled passengers and freight, including sectional canal boats, over the Allegheny Mountains. Eventually, advancing transportation technologies overtook the portage railroad. In 1854 the Pennsylvania Railroad, a private company, completed a route through the mountains without using inclined planes, making the Allegheny Portage obsolete. In 1857 the Pennsylvania Railroad bought the entire Main Line system from the state and began dismantling the Allegheny Portage Railroad. The Allegheny Portage Railroad National Historic Site preserves what little remains of this unusual transportation system.
Getting Started Prompt
Map: Orients the students and encourages them to think about how place affects culture and society
Readings: Primary and secondary source readings provide content and spark critical analysis.
Visual Evidence: Students critique and analyze visual evidence to tackle questions and support their own theories about the subject.
Optional post-lesson activities: If time allows, these will deepen your students' engagement with the topics and themes introduced in the lesson, and to help them develop essential skills.
