For decades now, passenger rail use has been steadily declining in the US, and although the country is criss-crossed with extensive railway tracks, the majority of these are used to carry freight, not passengers.
The U.S. rail system today is primarily used for long-haul shipping of bulk goods that are not sensitive. These would be commodities like crude oil, coal, timber etc. Over the years, this system has become very efficient at moving large quantities of goods over long distances very efficiently.
The Federal Railroad Administration does not currently set any limits on train lengths – and also doesn't regularly track train lengths or their associated risks. That has allowed freight railroad companies to occasionally operate trains up to 8 kilometres (5 miles) long.
During the post-World War II boom many railroads were driven out of business due to competition from airlines and Interstate highways. The rise of the automobile led to the end of passenger train service on most railroads.
Tracks: None of the nation's rail lines are built for trains to run 200 mph. Amtrak's Northeast Corridor — the busiest intercity U.S. passenger route by a wide margin — is filled with sharp curves, bottlenecks, decaying tunnels, bridges and overhead power lines that slow down trains.
American railways were also built on a wider gauge (the distance between the rails), which allows for larger and heavier trains. As a result, American freight railways are much more efficient than their European counterparts, carrying almost three times as much cargo per mile of track.
While trains are primarily used today in the U.S. as a means of commuting to and from work, luxury train travel experiences are still in motion on trains like America's Trains Southern Comfort line, featuring lavish sleeping cars, and the Napa Valley Wine Train offering food-and-wine day experiences.
Texas tops the list with 208 million tons of rail freight received each year. The Lone Star State is crisscrossed by a large network of railroads, making it easy for goods to move in and out of the state.
The United States possesses the largest railway network in the world, in terms of total operating length. China and India trail behind as the second and third largest railway networks respectively.
