An urban train link, the RER B, crosses Paris and its outskirts from north to south. A journey within indistinct spaces known as inner cities and suburbs. Several portraits, all individual pieces that form a whole. We.

This classic short film shows how to make an igloo using only snow and a knife. Two Inuit men in Canada’s Far North choose the site, cut and place snow blocks and create an entrance-a shelter completed in one-and-a-half hours. The commentary explains that the interior warmth and the wind outside cement the snow blocks firmly together. As the short winter day darkens, the two builders move their caribou sleeping robes and extra skins indoors, confident of spending a snug night in the midst of the Arctic cold!

In the first half of the 20th century, America's railroads were radically transformed by the innovation of gargantuan steam locomotives. Pushed by the need to haul ever longer and heavier trains, the nation's locomotive works responded with the invention of awe-inspiring articulated engines. Delivering up to 7,500 horsepower, these steel behemoths could haul mile-long, 15,000-ton trains. In this riveting program, journey back to the golden age of steam for an up-close look at these legendary locomotives. See the Union Pacific's famed "Big Boy" in action and ride the rails of the Chesapeake & Ohio and Norfolk & Western railways. Meet the men who drove engines like the Allegheny and Yellowstone, and visit the museums and yards where the largest steamers ever built remain preserved in time.

A group of people are standing along the platform of a railway station in La Ciotat, waiting for a train. One is seen coming, at some distance, and eventually stops at the platform. Doors of the railway-cars open and attendants help passengers off and on. Popular legend has it that, when this film was shown, the first-night audience fled the café in terror, fearing being run over by the "approaching" train. This legend has since been identified as promotional embellishment, though there is evidence to suggest that people were astounded at the capabilities of the Lumières' cinématographe.

A day in the city of Berlin, which experienced an industrial boom in the 1920s, and still provides an insight into the living and working conditions at that time. Germany had just recovered a little from the worst consequences of the First World War, the great economic crisis was still a few years away and Hitler was not yet an issue at the time.

THE STRAIT GUYS follows Czech-born mining engineer, George, and his fast-talking protégé, Scott, along the proposed route of the InterContinental Railway through Alaska, to the Bering Strait and onward to Russia. The “Strait Guys” endeavor to convince international governments, corporations, and indigenous tribes to green-light their $100 billion railway project, which would provide ground-based infrastructure across the continents, relieve overcrowded Pacific ports, improve global supply chains, and ease tensions between the superpowers. The US and Russia have been successfully collaborating in space for decades. Now the Strait Guys are out to prove it is also possible down here on earth.
