Who doesn’t LOVE massive old stream-powered trains?  Well, The Union Pacific 4014 “Big Boy” is not only one of the biggest, it’s also the world’s ONLY current operating Big Boy steam engine!  This Big Boy is visiting in honor of the 150th Anniversary of the Transcontinental Railroad.  You can check out the 16 feet tall, and 133 feet long locomotive when it arrives tomorrow, Friday, July 25th, at the Union Pacific Larry S. Provo Training Center at 2:30PM.  The train will be on display Saturday from 9AM to 4PM and on Sunday and Monday from 9AM to 3PM.  Then Big Boy hits the rails again, departing at 8AM on Tuesday.
