Unlike other engines on the rails, Bush 4141 is the only one to have ever been driven by its namesake and a former U.S. president.
Michael Iden, who worked closely with the crew to create Bush 4141, was aboard the historic ride.
Iden says Bush requested to take a tour of the locomotive the day after it was dedicated to him.

"The president looked at us and said with a smile on his face, 'Do you mind if I take it on a drive?'" Iden said.
After a brief lesson, Bush took control of the train and went on his first ride.
Since then, Bush 4141 has been in storage.

The locomotive was called to duty to transport President Bush from Houston to his final resting place at the George H.W. Bush Presidential Library behind the Texas A&M campus.
