The locomotive entered service with
Union Pacific as 8423 in 2005, initially entering service in primer paint, similar to the
six heritage units before they were unveiled in their respective paint schemes. On October 18, 2005, the locomotive was officially unveiled at the
George H.W. Bush Presidential Library and Museum with a paint scheme is based on that of
Air Force One, with lettering reading "George Bush 41". Union Pacific road number 4141 was previously occupied by an
EMD SD70M, which was renumbered 3778. The locomotive was displayed outside the Presidential Library for a while before it entered revenue service. Bush himself was allowed to operate the locomotive briefly. The unit was removed from active service in 2009 and placed in storage at UP's
North Little Rock shop when traffic fell after the
2008 financial crisis and the
Great Recession. In 2012, the locomotive was removed from storage for a single round trip from North Little Rock to
Chicago, then returned to storage. For a while, it was wrapped for long-term storage, but the wrapping was later removed. After
Bush died on November 30, 2018, UP 4141 was brought out of storage and sent to
Houston, Texas, on December 1, 2018. The locomotive participated in Bush's
funeral train on December 6, running from
Spring to
College Station, Texas. After the funeral, the unit was sent to
Omaha, Nebraska, where it was displayed from December 9 to 12. UP 4141 later went on a system-wide tour, with stops in Chicago,
Fort Worth,
Houston,
Kansas City,
Los Angeles,
North Platte,
Pine Bluff,
North Little Rock, Ogden,
Portland, Roseville and
St Louis. Following the tour, it returned to active service, in addition to being on display in other locations. On November 8, 2019, Union Pacific donated the 4141 to the
George H.W. Bush Presidential Library and Museum, where it would be on permanent display in the pavilion. The locomotive made its last run from November 8 to 9, traveling from Houston to
Palestine, Texas as part of the Southwest tour of the recently restored
Union Pacific Big Boy No. 4014. Following its last run, it was taken back to the North Little Rock shops to be prepped for display. On March 12, 2021, the locomotive arrived back at College Station. The Marine One/4141 Locomotive Pavilion was opened on June 13, 2024, in time for George H. W. Bush's 100th birthday. ==References==
