'Big Boy', the world's largest operational steam locomotive, is coming to Houston

The world's largest operating steam locomotive will be in Houston this October.

Union Pacific's Big Boy No. 4014 is making a stop in Houston as a part of its Big Boy Heartland of America Tour.

25 "Big Boys" were built during World War II, but only eight survived. No. 4014 is the only one in operation. 

The train left Dallas on Thursday morning and will make a stop in Hearne for maintenance before heading to Houston.
