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.

🎃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.
