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-ton, 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.

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.

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?

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.

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.

USS Kittiwake operated as a Navy submarine rescue vessel for nearly 50 years before being decommissioned in 1994. Now she’s being transformed into an artificial reef and underwater adventure for sports divers to explore. She must survive the trek from Norfolk, VA to the Cayman Islands and sink on target to land upright on the Caribbean Sea floor. Meet the teams in charge of this titanic task and follow their 1,600-mile journey through winter storms and huge swells.

A vintage aircraft collector’s childhood dream of flying a British Supermarine Spitfire is about to come true. After spending $2.5 million buying and restoring the iconic WWII fighter, the next challenge is getting it over the Atlantic to its new home in Maryland. The plane can’t carry enough fuel to fly to the U.S., so a team of engineers must dismantle the classic aircraft, ensure it survives a 4,000-mile voyage, then reconstruct it to make it airworthy once more.

In the early 1940s, Winston Churchill exported 20 Stanier 8F locomotives to Turkey to encourage the country’s neutrality in WWII. Now, after 70 years away from the U.K., two of these classic trains are heading back home. Follow a team of train enthusiasts as they struggle to haul these two historic engines 850 miles across Turkey’s remote, mountainous terrain.

Two teams of heavy haulers face two massive jobs involving a vintage submarine attack aircraft from the Cold War and a railroad snowplow built in 1925. First, the last airworthy Fairey Gannet has to hitch a ride out of Goose Bay Airbase in Canada aboard the Antonov-124 cargo aircraft. Meanwhile, in Oregon, a team of movers fights gravity and narrow roads to pull the Union Pacific snowplow locomotive up the treacherous “Train Mountain.” Will both mammoth machines survive these perilous journeys and reach their new homes in one piece?

A flotilla of trimaran and monohull yachts are lined up for the Route du Rhum, a transatlantic race spanning 4,000 miles from France to the Caribbean. For the skippers who make it to the tropical finish line, they’ll face another challenge almost as big as the race itself: how to transport their boats back home in the ocean’s notorious winter storms. Follow the moving crew as they attempt to fit 17 yachts worth over $10 million aboard a massive cargo ship in order to bring them back to Europe.

In Chile, 16,400 feet above sea level, astronomers, engineers, and technicians are building the world’s biggest telescope, a scientific wonder capable of gazing into the farthest reaches of the universe. Follow two massive moves—one to haul a huge dish 7,000 miles from its factory in France to the Atacama Desert, and the other to carry the antenna up a desert mountain aboard a custom-designed, 28-wheeled transporter.
