The Acoma in storage at Albuquerque 2021 at the Rail Runner facility. It is now in excursion service on the Sky Railway (the old Santa Fe Southern, and same train and location used in Breaking Bad) that runs between Santa Fe and Lamy. It crosses the same bridge where Walt, Jessie, and Todd broke into the tank car and pumped the chemical into a tank they buried in the ground.
I took this photo below before the line was sold to the new owners and repainted into the Dragon scheme that it is now.
Photo below is the employee entrance to the Albuquerque Amtrak Depot, and employees of the Rail Runner. Also where Saul Goodman parked his car to sell burner phones out of his trunk.
