On November 8, 2019, the Union Pacific Railroad donated its EMD SD70ACe locomotive #4141 to the library, where it will be on permanent display in the pavilion. The exhibit is currently expected to open in 2020 and will be placed between the library and the Annenberg Presidential Conference Center. Unveiled on October 18, 2005 in honor of Bush, it remained in active service until 2009, and later was brought back to participate in Bush's funeral train on December 6, 2018. It 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. 4141 is currently being prepared for display at the North Little Rock Shop.
