LIVE: Big Boy - World's Largest Steam Locomotive in Fort Worth | FOX 4

The world's largest operating steam locomotive will be in Fort Worth through the weekend.
Union Pacific's Big Boy No. 4014 will chug into Fort Worth on Wednesday night.
The 133-foot-long and 1.2 million pound black locomotive, will be on display at 275 W. Lancaster Avenue from Thursday from 9 a.m. to 3 p.m. and Friday from 9 a.m. to 1 p.m.
Admission to the event is free.
The City of Fort Worth suggests parking at the Convention Center Parking Garage at 1200 Houston Street.
The train will be a part of a private Union Pacific event on Saturday and the locomotive will leave Fort Worth on Sunday, Oct. 13 at 8 a.m.
Big Boy made a stop in Dallas last month, but only for a private event.
The stops are a part of the Big Boy Heartland of America Tour, which takes the train through 10 states.
You can track the engine's current location on Union Pacific's website.
25 "Big Boys" were built during World War II, but only eight survived. No. 4014 is the only one in operation.
