(CNN) - With plumes of smoke billowing into the sky, the world's largest steam locomotive left Wisconsin on Friday morning, bound for an afternoon stop in West Chicago.
Back on the rails for the first time in six decades, the only operational Big Boy steam engine in the world is on a journey across the Midwest to mark the 150th anniversary of the completion of the Transcontinental Railroad in 1869.
The steam engine stopped Tuesday in Altoona, Wisconsin, about 90 miles east of Minneapolis.
The 600-ton locomotive left Butler, Wisconsin, at 8 a.m. Friday en route to Chicago, Trains magazine says.
