What mode of transportation succeeded the mode noted in Problem 1-19, and what advantages did it offer?
What will be an ideal response?
Canals were succeeded by railways as the primary mode of long-distance travel. Railroads first appeared in the U.S. around 1830. By 1840, the mileage of railways was approximately equal that of canals. Railroads continued flourish while investment in canals declined. Locations for railroads were not confined to watercourses and therefore could be built almost anywhere.
