The region will say goodbye to two historic locomotives this week as they head home to North America.
Dwight D Eisenhower and Dominion of Canada are part of the 'Big Six' A4 Class.
They have been on display at Locomotion, the National Railway Museum at Shildon in County Durham, alongside their sister engines which include Mallard.
In 1938 Mallard became the world's fastest steam locomotive when it reached a speed of 126 miles an hour on the East Coast Main Line.
Mallard was reunited with the others in its class as part of the 75th anniversary commemorations.
