November 13, 2019 – What a day!! I chased Union Pacific’s 4014 “Big Boy” from Prescott to Little Rock, Arkansas and couldn’t have asked for better weather! The cold really made the steam and smoke pop! Here we see 4014 as it departs Prescott early in the morning, after a slight delay to let two trains pass it. There’s just something about a steam locomotive when it pokes its nose out of a cloud of steam!
