Rail Force One: George H. W. Bush's Union Pacific railcar

Have you heard of UP 4141? Better known as Union Pacific 4141? It's a specially painted locomotive honoring the 41st President of the United States, George H. W. Bush. According to Union Pacific, the locomotive is expected to operate for up to 1 million miles before being decommissioned (it was dedicated in 2005 near the George Bush Presidential Library and Museum on the Texas A&M University campus in College Station, Texas).

A few lucky railfans have taken photos of the locomotive (see here and here) and a quick search on YouTube shows a few individuals who have captured it on video as well. Here are a few videos of it.
