Union Pacific 4141 is an EMD SD70ACe locomotive owned by Union Pacific. Its paint scheme is based on that of Air Force One and "George Bush 41" is painted on the sides in honor of the George Bush Presidential Library and George H. W. Bush, the 41st President of the United States. The road number 4141 was previously occupied by an SD70M, which has since been renumbered to 3778.
The unit was removed from active service due to reduced traffic levels stemming from the financial crisis of 2007–2010 and was stored at UP's North Little Rock shop. The locomotive was briefly removed from storage in 2012 and made a round trip from North Little Rock to Chicago, and was then immediately returned to storage. For a while, it was wrapped for long term storage, but the wrapping was later removed. During February 2018, 4141 received cosmetic touch ups to its paint and then returned to storage.
After the passing of George H. W. Bush on November 30, 2018, UP 4141 was brought out of storage and was sent to Houston, Texas on December 1, 2018. The locomotive participated in the funeral train for George H. W. Bush on December 6, running from Spring, Texas to College Station, Texas. Following the funeral, the unit was sent to Omaha, Nebraska, where it was on display from December 9 to December 12.
