7x1 - The City Beneath Our Feet
January 3, 2000
Beneath every modern city, hidden by manhole covers, drains, and ventilation grates – lies a labyrinth of tunnels, wires, conduits and pipes. They deliver power to our homes, water to our faucets, messages to our loved ones and sometimes – they even move us. Workers create the secret world beneath our feet using everything from shovels, pickaxes and dynamite to multi-million dollar tunneling equipment. The modern subterranean worker, or as they like to be called, “Sandhogs” use time tested methods as well as modern inventions, such as airlocks and computerized mapping techniques to avoid pitfalls and get the job done in the city beneath the street.

The world’s largest bascule bridge (a counterweighted drawbridge), when it was erected in 1892, it became a postcard image of London. The famed gothic towers of this pioneering steel structure, sheathed in stone, are purely decorative.
7x3 - The Chunnel
January 11, 2000
The challenge of linking Britain and France with a tunnel under the English Channel was both monumental and delicate. It took 18 months just to design and build the 28 foot diameter TBMs, and nearly a year to assemble and position them underground. Modern Marvels takes you through the entire process from start to finish.

Pack your bags or lunch and travel down the road of bus history.
7x18 - Gold Mines.
June 22, 2000
Around the world and across the eons, gold stands as a symbol of power, wealth, and love. The quest for the yellow metal took men across oceans, into the depths of the Alaskan winter, and miles beneath South African earth. This is the story of the hunters of the precious metal and their methods for extracting it.
7x19 - Banks.
July 27, 2000
Backbones of worldwide economics, for centuries banks enabled the creation of wealth, and industry leaders became icons.

From banking's early European origins to "e-banking", this is an hour you can't afford to miss!
7x20 - The Erie Canal
July 31, 2000
The Erie Canal was America’s first superhighway. It was a narrow ribbon of water carved through sheer rock and untamed wilderness. It featured an ingenious network of stone locks and aqueducts.

From 18th-century steam-powered carriages to tomorrow’s computerized trucks, it’s a long haul you’ll enjoy!
7x22 - Aswan Dam
August 14, 2000
In 1954, Gamal Abdel Nasser, the Arab Republic of Egypt’s first prime minister, had a plan to bring his poor country into the 20th century. To pull it off, he needed to harness the flow of the world’s longest river–the Nile. The ambitious plan called for construction of a high dam in southern Egypt at Aswan. But the builders of the pyramids and the Suez Canal were no strangers to large undertakings. We’ll see how the Aswan High Dam socially, politically, culturally, and agriculturally affected Egypt.
7x23 - China's Great Dam
August 22, 2000
When completed, China’s Three Gorges Dam will tower 607 feet in the air and weigh 40 Great Pyramids. Other than China’s Great Wall, it will be the only man-made object visible from the moon. Supporters see it as key to a new China, controlling floods and bringing hydroelectric power to one of its least-developed areas. Critics voice a litany of concerns–from environmental to flooding the spectacular area for which it’s named. We trace its story–from ancient flood control to current controversy.
7x24 - The Maginot Line
September 10, 2000
The Maginot Line, a defensive string of large and small forts built during the years between World War I and World War II, was intended to forestall another invasion by aggressive Germany. Despite the Treaty of Versailles, France saw that it was only a matter of time before Germany would rise again and threaten France. News of northern neighbor Belgium’s neutrality left France with an exposed flank, which would ultimately be the Maginot Line’s weak point-the Germans were able to outflank the line almost entirely, readily conceding the Line’s impregnability while conquering the country.

7x27 - Machine Tools
October 9, 2000
No one wants a hand-made car or gun or an airplane. We want things made by machines. Machine tools are power–driven machines–of all shapes and sizes-used to make metal parts. Machine tools built our modern world. Our life would not be possible without them. This show will take a look at these amazing machines in action. Beginning with the story of the steam engine and traveling to modern day “machining centers”–used to make incredibly complex space shuttle parts–we’ll look at the basic types of machine tools and their development. We’ll also look at some of the most modern machine tools of the future, including machines that are changing the way products of tomorrow are made.
7x28 - Farming Technology
October 15, 2000
The US agricultural process, from seed to shelf, is so efficient that most people don’t think much about it. But food growing and processing is ever more sophisticated, employing computer-guided, ground-shaking machinery, and sometimes controversial techniques. It’s an industry of declining family farms, diminishing returns, yet higher yields. We review the evolution of the tools used to produce food, show the steps in the cycle that bring food to the table, and look at the future of farming.
7x29 - Assembly Lines
October 16, 2000
According to the Encyclopedia Britannica, an assembly line is an “industrial arrangement of machines, equipment, and workers for continuous flow of workpieces in mass production operations.” While the basic principles of the assembly line technique have not changed in one hundred years, the people and the products that exploit the technique have. Throughout the hour, we will hear from four generations of assembly line workers who will provide some perspective, heart and soul for this revolutionary production technique.
7x30 - Suez Canal
October 17, 2000
Since the ancient pharaohs’ time, the Isthmus of Suez has been the gateway to trade between East and West. It’s thought that the pharaohs could connect the Red Sea with the Mediterranean using a system of small canals; but the desert sands buried them. Not until mid-19th century did mankind readdress the problem. Since its completion in 1869, the Suez Canal has been a vital link in world trade and a point of controversy in geopolitics. Today, more than 20,000 ships transit the canal yearly.
7x31 - London Underground
October 18, 2000
Deep beneath London runs a complex network of many miles of tunnels; and, while traffic congests the roads above, hundreds of trains run through these iron and concrete arteries, carrying millions of people into, around, and out of the City. Here is the story of the “Tube”, the world’s first underground railway, which holds London together–from its opening in January 1863, through its deep-level expansion and electrification, to the fully automated trains of the 21st Century’s Jubilee Line.
