The Big Boy #4014 is thundering down the mainline once again in this jam-packed program, including her epic doubleheader with 4-8-4 #844 from Cheyenne, WY to Ogden, UT and back! See her climb Sherman Hill, Peru Hill, and the Wasatch Grade. Great action in Weber and Echo Canyons and attend the 150th anniversary of the completion of the transcontinental rail at Golden Spike National Historical Park.
