Overview: A team of British engineers attempt to haul two historic A4 Pacific steam locomotives - each worth more than £2 million - more than five thousand miles across the Atlantic to the National Railway Museum in York. The A4 Pacific locomotive smashed the rail world speed record in 1938, thundering to over 126 miles an hour. To celebrate this record’s 75th anniversary the museum is shipping all the surviving A4 Pacifics to the UK for display. For specialist train trucker Andrew Goodman and his crew, this transatlantic train trek is their toughest challenge yet. The locomotives are no longer able to run under their own steam and need loading onto freight trains where there’s the constant risk these massive but fragile machines could disintegrate. Will the team haul the engines to the docks in time to load them onto their ship back to Britain?
