🎃Since 1862, Union Pacific has delivered Halloween essentials. While none of them travel behind the Big Boy, it is rather fitting for #spookyseason. Our yellow locomotives haul more than 30,000 carloads of sugar, corn syrup, peanuts and chocolate.

Union Pacific's Big Boy No. 4014 recently had the privilege of carrying an American flag in honor of former railroad engineer Fred Campbell, as a tribute to a service member during one leg of its journey. The flag was then presented to Fred's family in Wilson, Kansas.
