|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.|
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.
Quote from Worlds Greatest Steam Locomotives by Eugene L. Huddleston:
There were 25 locomotives
fabricated in two different groups. Class 1 were locomotives #4000-4019
and Class 2 was numbered 4020-4024. The first Big Boy #4000 was
delivered to Omaha, NE on September 5, 1941. UPs commitment to the Big
Boy required them to replace the lighter rail and straighten out many
miles of trackage for clearance as well as to resize elements of their
service areas (such as turntable lengths, etc.) for the entire line
these locos would run on.
The Big Boys demonstrated
fantastic strength and speed as they faced these challenges throughout
their storied careers. With the total mileage on the Big Boy fleet being
approximately 1,000,000 miles for each locomotive, one must say that
they earned their reputation.
Several examples remain in
museums around the country but silently they sit as a visual echo to the
thunder that once made them revered throughout the landscape that the
Big Boys dominated.
