  the work of the railroad pioneers in america became the basis for a great surge of railroad building halfway through the nineteenth century that linked the nation together as never before. railroads eventually became the nations number one transportation systemand remained so until the construction of the interstate highway system halfway through the twentieth century. they were of crucial importance in stimulating economic expansionbut their influence reached beyond the economy and was pervasive in american society at large.

  by 1804, english as well as american inventors had experimented with steam engines for moving land vehicles. in 1920, john stevens ran a locomotive and cars around in a circular track on his new jersey estatewhich the public saw as an amusing toy. and in 1825, after opening a short length of trackthe stockton to darlington railroad in england became the first line to carry general traffic. american businesspeopleespecially those in the atlantic coastal region who looked for better communication with the westquickly became interested in the english experiment. the first company in america to begin actual operations was the baltimore and ohiowhich opened a thirteen- mile length of track in 1830. it used a team of horses to pull a train of passenger carriages and freight wagons along the track. steam locomotive power didnt come into regular service until two years later.
