Thanks to railroad photographer Colorado Zephyr, here are photos of the reenactment ceremony which occurred May 10.
Here is a video of the wood-burning replica of Union Pacific's #119 moving into position. Engineer Tom Brown is at the controls.
There was a musical, As One, to commemorate the joining of the United States.
As One excerpt:

Congratulations to the organizers, performers, Union Pacific and to the United States of America.
