UP BIG BOY 4014 on Donner Pass! (featuring Amtrak & UP freight) 7/14/2024 - Roseville to Sparks

Check out the scenes from Sunday, July 14th as Union Pacific’s Big Boy no. 4014 assaulted the steep grades of legendary Donner Pass! This is the first time a locomotive of this class has ever gone up the impressive summit, and it’s the largest to ever conquer it! Amtrak’s California Zephyr also makes appearances, as both the eastbound and westbound trains glide by. We also get a westbound hotshot Z-train on its way to Oakland!
