Having spent most of her working life with the LNER and later as British Railways No. 60008 she was withdrawn from service at her last steam shed at New England, Peterborough in July 1963. The following year in 1964 after a cosmetic make over at Doncaster Works No. 60008 was gifted to the National Railroad Museum at Green Bay, Wisconsin in the United States of America for preservation as a static exhibit there. The A4 was moved from Doncaster to Southampton Dock where it was loaded aboard the cargo ship "American Planter" that transported the locomotive from the UK to the USA arriving in New York and then transported by rail to Green Bay in May 1964 as the only LNER A4 Pacific in the United States of America.

The A4 is displayed along with two LNER teak bodied coaches that were used by Eisenhower that were part of his command train in the UK during the Second World War. In October 1990 No. 60008 made a visit to Abilene in Kansas to go on display there to mark the centenary of Eisenhower’s birth. The move there and back both ways was done as a special train at slow speed, since the locomotive and two cars from the command train used the British vacuum braking system, incompatible with the American air-braked trains.

From 2012 to 2014 No. 60008 was famously temporarily repatriated to the UK along with sister A4 No. 60010 or LNER No. 4489 "Dominion of Canada" for the 'Great Gathering' marking the 75th anniversary of sister A4 No. 4468 "Mallard" becoming the worlds fastest steam locomotive at the speed of 126mph a world record that still stands today. For this No. 60008 was cosmetically overhauled, in the workshops of the National Railway Museum in York which saw a new coat of authentic BR Brunswick Green paint to replace the inaccurate shade applied during a repaint at Green Bay.

In 2013 The Great Gathering was held in the Great Hall of the National Railway Museum in York which saw all six surviving LNER A4 locos together from No. 60008 "Dwight D Eisenhower", No. 60007 "Sir Nigel Gresley", No. 60009 "Union of South Africa", No. 4464 "Bittern", No. 4489 "Dominion of Canada" and No. 4468 "Mallard" for the first time since the end of steam in the UK in the 1960s. During her time back home in the UK No. 60008 was on display at York for a few months and visited Barrow Hill Roundhouse in Derbyshire before finally visiting Locomotion at Shildon in County Durham for the 'Great Goodbye'. The 'Great Gathering' was a once in a life time event and will go down as the greatest gathering of steam locomotives in preservation. After this No. 60008 was returned back to the United States of America and back home to the National Railroad Museum at Green Bay, Wisconsin where the A4 is the centrepiece telling the story of railways during the Second World War in the UK, Europe and the United States of America and continues to be the only A4 in the USA today. Will 60008 return to the UK again? Well, it's unlikely but never say never as anything could happen in railway preservation.
