Smithsonian Ch. - Humongous Moves: Series 1 (2013)

Across land, sea, and air, they carry the most massive, fragile, and expensive cargoes on the planet to destinations hundreds, even thousands, of miles away. Follow the teams of engineers tasked with planning and executing the world's most nail-biting moves. Through each daring and dangerous relocation and amidst tough conditions and tight deadlines, these heavy haulers must overcome incredible challenges to get their colossal cargoes to their new homes.

Part 1: Supersized Submarine
The Royal Naval docks of Halifax are cluttered with decommissioned Oberon-class submarines. Once a vital weapon of the Cold War, these O-boats are heading for the scrapyard, all except the HMCS Onondaga, which is destined for a museum 700 miles away, if it can ever get there. Follow a daring team of marine engineers as they attempt to tow this 1,400-ton submarine up Canada's coast in the face of a hurricane, and then haul it over rocky shores and onto a perilously steep railway. It's a massive move, and the stress factor is just as large.

Part 2: Titanic Train Trek
The National Railway Museum in York is home to centuries of Britain's railway heritage. One of its star attractions, a historic A4 Pacific locomotive, is about to be joined by two more A4s from North America, but only if they can get there. Join a crew of British engineers as they haul these 94-tons, three-million-dollar steam locomotives, one from Green Bay and one from Montreal, across the Atlantic. For this experienced team, it will be their toughest challenge yet, requiring freight trains, cargo ships, trailers, and nerves of steel.

Part 3: Gigantic Gun
The Royal School of Artillery in England has a 200-ton problem. Its huge WWI railway howitzer needs to be hauled nearly 400 miles to the National Railway Museum in Utrecht, Holland, in less than a week, but there's no one to move it. At the 11th hour, a transport company comes to the rescue, but before they get on the road, they'll need to split the metal monster in two. Witness this humongous haul as the team battles rising tides, jammed roads, and a tight deadline to get this showpiece exhibit to Holland in time for its grand unveiling.

Part 4: Huge Helicopter
The Sikorsky S-92 is the ultimate search and rescue helicopter, a high-tech, all-weather machine. The Shetland Coastguard is eagerly awaiting the arrival of one but it's still in a Pennsylvania factory 3,500 miles away. That's too far for a chopper to fly alone, so it's going to need an escort. Enter the Antonov 124, a Cold War warrior with record-breaking cargo capabilities. Antonov is big, but so is the Sikorsky S-92, an eight-ton beast. Can a team of engineers squeeze this $30 million aircraft in and get her to the Shetlands unscathed?

Part 5: Floating Fortress
A team of engineers is on a mission to build and sail seven floating homes across the Netherlands, from a factory in Urk to a new waterborne community 70 miles away. The route, however, proves to be an obstacle course of boat traffic, unexpected swells, and low bridges, not to mention precarious cranes and narrow country roads when they reach stretches of land along the way. Will these luxury dream homes make it to their destination undamaged? Take a ride through a maze of Dutch riverbanks and waterways to find out.

Part 6: Huge Hovercraft
The Canadian Coast Guard, which protects the beachfront city of Vancouver, is in desperate need of a new breed of rescue vehicle. The solution is the AP1-88 Hovercraft, a 100-foot marine machine. The challenge is it's still being assembled in Southampton in a factory 9,000 miles away. Follow a team of engineers as they attempt to build and haul it across the Atlantic Ocean, through the Panama Canal, and up the West Coast of the U.S. and Canada without incident.
