The New York subway became the word’s largest mass transit system shortly after it opened in 1904. Today, it carries fully one-third of all mass transit passengers in the United States. But after decades of neglect, New York’s once great subway is nearing collapse.

An enormous renovation effort will transform the city’s subways and commuter rails into the most technologically advanced mass transit system in the world – that is, if all goes as planned. Structural engineers grapple with the difficulties of updating the transit system whilst still keeping it open to the public, and city planners work to strike a balance between attracting even more people to the city and transporting them effectively.

Documentary looking at the logistics of docking a container ship at Long Beach, California, and the operation of the waterfront docks, where several thousand containers need to be unloaded and loaded within a 48 hour timeframe.

Also covered is the building of the Adrian Maersk, the world’s largest container ship. Even with the enormous size of such ships, construction must remain accurate to within millimetres of the design specifications.

With rising temperatures and rising gas prices, cars need to become greener fast. And on the surface, the large car manufacturers seem to work hard to improve the fuel efficiency of their products. But are they working as hard as they say?

The technologies which make cars more fuel efficient has already existed for decades, but never make it as far as the showroom. Why do we have to wait so long for fuel efficient vehicles?

Documentary exploring the feasibility of a hypothetical bridge spanning the Bering Strait between Cape Dezhnev, Chukotka, Russia, and Cape Prince of Wales, Alaska, United States. The bridge would provide an overland connection linking Asia, Africa and Europe with North America and South America.

The Bering Strait could be spanned by a series of three bridges via the Diomede Islands for a total distance of about 80 km (58 miles). The two long bridges would each be slightly longer in length than the Hangzhou Bay Bridge, currently the longest sea-crossing bridge in the world. The construction of such a bridge however, would face unprecedented engineering, political, and financial challenges.

Deep beneath London runs a complex network of many miles of tunnels. 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.

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.
