Locomotive Leaving Cheyenne

Cheyenne, Wy – The world's largest operating steam locomotive -- Union Pacific Railroad's Challenger -- will embark on a nine-state, 35-hundred-mile tour on its way to Houston and Super Bowl 38 activities.
The Challenger, also known as Number thirty-nine-eighty-five, will depart from Cheyenne on January 12th at 8 in the morning.
From there it will head through Nebraska, Colorado, Kansas, Missouri, Illinois, Arkansas and Texas.
On its return trip, the Challenger will pass through Oklahoma and arrive back in Cheyenne on February 12th.
U-P officials say the engine rarely makes winter tours.
The locomotive, which is based in Cheyenne, is 122 feet long and weighs one million pounds.
It was retired in 1959, then restored by Union Pacific volunteers in 1981.
Another of its type -- number four-Oh-Oh-four -- sits at Cheyenne's Holliday Park.
