Railfanning the Union Pacific Gila Sub: 4014 Drifts into GIla Bend, AZ, 10-16-19

A sight I never thought I'd see: A fully restored, working Big Boy, that hasn't run in revenue service since I was 2 years old! Here we see the iconic locomotive enter Gila Bend, Arizona and stop for its scheduled checkup. Enjoy the lovely whistle!
