7237 UP Big Boy #4014, Promontory Excursion, Glossy Finish, Challenger Excursion Tender, Paragon4 Sound/DC/DCC, Smoke, N

Often called the largest steam loco ever made, and certainly a contender for the Worlds Most Famous Locomotive, the Big Boy was forged under some of the most strenuous demands ever placed on a locomotive. The UP Railroad needed a locomotive that could be used to pull a 3,600-ton train over Sherman Hill and the 1.14% grade from Ogden to Wasatch, Utah without the need for helpers.

When the design specifications were complete, it was decided on the use of a simple articulated, high speed, 132 ft. long locomotive sporting sixteen 68 diameter drive wheels. What they created was the longest and among the heaviest, most powerful steam locomotive legends in the world. And had not the worker at ALCO chalked Big Boy on the side of the smoke box of one of the 4-8-8-4s under construction, a name that immediately caught on, it is rumored that the name of the type would have been Wasatch, for the mountains they were built to conquer.
