On October 2005, Union Pacific paid tribute to President George Herbert Walker Bush with a custom-painted locomotive. Incorporating colors and elements of the Air Force One used during Mr. Bush’s presidency, the new Union Pacific locomotive bears the number 4141, in honor of the 41st president. The special locomotive, which replicates the Raymond Loewy-designed Air Force One markings as a striking symbol of national pride and strength, was revealed to the former president during a ceremony near the George Bush Presidential Library and Museum on the Texas A&M University campus in College Station, Texas.

PROTOTYPE SPECIFIC INFORMATION

In order to meet stricter diesel locomotive emissions standards imposed by EPA Tier II regulations, EMD modified the SD70MAC to create the SD70ACe and SD70M-2. Each model is powered by a 16-cylinder, 4300-horsepower diesel engine. On the SD70M-2, the prime mover drives an alternator and produces AC current that is rectified to DC current, which powers the traction motors. On the SD70ACe, the DC current is then “chopped” back into AC to power the traction motors.

On December 6, 2018 UP 4141 led the funeral train carrying the late President George H. W. Bush from Spring, TX to Texas A&M University for his burial at his Presidential Library and Museum.
