The first unit was delivered in 2022 and is expected to enter service in 2023. Operators Preservation On November 8, 2019, Union Pacific donated SD70ACe No. 4141 to the George H.W. Bush Presidential Library and Museum. The locomotive, painted in honor of George H. W. Bush, was unveiled in October 2005 and was in active service until 2009, when it was placed into storage due to the financial crisis of 2007–2010. It was brought back in 2018 to participate in Bush's funeral train on December 6, 2018. The locomotive subsequently remained in active service following the funeral until its last run between November 8 and November 9, as part of the Union Pacific 4014 Southwest Tour, in which the plans for the display were unveiled. The locomotive arrived back at College Station on March 12, 2021 and is now undergoing final preparations for the opening of the display.
