The Canal Age is a term of art used by historians of Science, Technology, and Industry. The Canal eras in various parts of the world have varied in the world timeline, in the main, by civilizations (Egypt, Ancient Babylon), dynastic Empires of India, China, and Southeast Asia, and of European mercantilism. Canals are culturally dependent, and culture creating, part of industry, and industry creating and until the coming into an era when steam locomotives generated refined speeds and sufficient power, the canal was by far the fastest way to travel long distances quickly, for commercial canals generally had boatmen shifts that kept the barges moving behind mule teams 24 hours a day. Like many North American canals of the 1820s-1840s, the canal operating companies partnered with or founded short feeder railroads as were necessary appendages to connect to their sources or markets. Two good examples of this were funded by private enterprise:

Together, they and the Schuylkill Canal-Reading Railroad would supply and transport the majority of Anthracite needed by northern industries in the early North American Industrial Revolution. Unlike Europe, America did not have canals for several hundred years before industrialization. In North America, everything grew up together all at the same times.

Early railroads in North America made many canals economically feasible, and canal's needs added to the demands by industries that pushed the early railroads into pressurized research and development and rapid steady improvements.

Technology Archaeologists and Industrial Historians date the American Canal Age from 1790 to 1855 based on momentum and new construction activity, since many of the older canals, however limited later by locks that restricted boat sizes below the most economic capacities and well-behind later-developing technological capabilities, nonetheless continued on in service well into the twentieth century. In truth, the first legislation supporting canals in North America took place in the Province of Pennsylvania in 1762 with an effort to improve navigation on the Schuylkill River through Philadelphia, the largest city in North America and the surveying of a canal along the Schuylkill tributary Tulpehocken Creek which would eventually be built in 1828 as the Union Canal part of the omnibus Pennsylvania legislative package, the Main Line of Public Works, providing the only water route connecting the Susquehanna with the Delaware above the Potomac & Chesapeake Bay.
