An informative look at that amazing "hole in the ground"--New York City 's subway system. Meet the riders, a towerman, a revenue agent collecting the day's cash from token booths, a string quartet of amateur musicians who perform at the stations, and others who make the subway one of the most fascinating public spaces.

The colorful history of street railways, from turn-of-the-century horsecars to today's sleek light rail systems. Uses rarely seen film from archives and private collections to recall a fascinating part of urban history.

In one of the greatest building achievements in history, East and West were joined by a thin ribbon of steel and wood. But would the railroad conquer the wild, open country?

It's the longest, most expensive and complicated railroad ever built. Ordered by the Czar in an effort to save his empire and unify his country at the twilight of the 19th century, the Trans-Siberian Railroad nearly tore Russia apart. Intended in part for defense, the railroad provoked a war, crossed great lengths over treacherous terrain, and encountered logistical and economic failures. Ironically, "enemies of the state" built the railroad--men sentenced to hard labor in Siberian prisons.

Zip through the French countryside at nearly 300 MPH on the TGV--the fastest locomotive in the world. Ride on the little engines that could as they guide giant ships through the Panama Canal. Watch two locomotives crash head-on as the federal government monitors safety. Descend 700 feet below the earth's surface where mining locomotives move miners through a maze of tunnels. Then, it's a "jiffy lube" for locomotives inside America's largest maintenance shop. Finally, glide into the future with a locomotive that levitates on a cushion of air.

Traveling between 135 and 190 miles per hour with an astonishingly high safety record, bullet trains can be found throughout Europe, Japan, and on the US eastern seaboard. How high-speed trains are propelled is rooted in fundamentals that haven't changed since the first electric trolleys appeared in the 19th century. We see how scientists are looking at new alternatives to electricity, including magnetic levitation that can move passenger trains 345 miles per hour and beyond!

There is no more potent demonstration of man's resolve than the design and construction of tunnels--avenues that slice through a conspiracy of elements in the single-minded determination to connect two points. Whether underwater, blasted through solid rock, or negotiating the shifting strata of earth's unstable crust, we explore the design and engineering of famous tunnels...and the motivation behind them.

Its efficiency has produced billions of products, from toys to Boeing 747s, cheaply and quickly. Follow the evolution of the assembly line, including its sometimes troubled relationship with the human beings who make it work. We'll see how Americans eventually overcame prejudices toward black people and women in the factories during World War II. And we'll follow a family of four generations of Detroit auto assembly workers as they tell us how they dealt with the relentless pace of production. During the 1930s, assembly lines' frantic pace led to widespread labor unrest; and in the 1970s, it was a symptom of a greater concern for quantity than quality.
