THE LARGEST LOCOMOTIVE.
BUILT FOR THE CARNEGIE STEEL CONF
PANY AND kBLE TO HAUL A FREIGHT
STEAMERS CARGO

A leviathan on wheels has just been intro
duced the system operated in connection with
the various works Of the Carnegie Steel Com
pany The locomotive is the largest and heavi-
est in the world powerful enough. if ii were put
TO that test to haul more than the entire cargo
of a great freight steamer 1t was built by the
Pitisburg Locomotive Works on an order from
the Union Railroad Company, Of Pitts5urg.
1t is not only larger and heavier as whole
than any locomotive previously built, tux eA-
ceeds all others in many of It's essentld' ut'a'l''
The weight on the drivers is 2oN'oVo Houhus'
The Mexican Central double-boiler locomotives
have 100000 pounds on two separate oil'"e-
wheel bases and the tank locomotives u VIC
St Clair tunnel have 190,O0O pounds on Ten INV
ing wheels The twelvc-wheel locohouNe9 y.
the Great Northern Railroad have .o'di
weight of 2l2 80 pounds Of which only i'-,oV'
hounds are en- the driving wheels. Tne C!hhuei"
of the new locomotive are % by - lnohes' as
compared with II by 81 inches for the "rea'
Northern and its total boiler heating surface -
:,22 square feet, as compared with bow u" wv
creat Northern. II not only has greater weight
an it's drivers but exceeds also IN cyIhder
mower and in the steam producing capacity OF
its boiler the most powerful locomotives ever
constructed.
is furnished by the character OF the Work oe
,ondd ofu ahout four miles Of the line upon
vbich il is operated has a grade of 40 feet
mile and on one stretch Of about two thousahd
feet m across the main line Of the PeLhsyi-
vania Railroad and reaching to the foot oi
seventy foot hill has a grade Of ~ per cent LIE
trains Of many cars are loaded down VII" "o"'
coke and mill and furnace products, and asgre-
gate many tons to a car. The locomotive is now
in daily use. and is said to be highly satisfac-
tory not only in the work accomplished but III
the economy Of fuel and water required.
The New w-York Central Railroad recently ac-
complished what was considered rem frkabie
feat in the hauling of train Of SVoOV hushelS
of grain a distance of 40 miles with single
mogul locomotive. having weight oi l-""o'
pounds on its drivers. 1t is estimated mat the
new locomotive on such track as the New
York Central from Syracuse to Albany coud
haul a paying load Of $4,000 bushels II gram
or a net weight Of 1910 tons.
In the Pitsburg locomotive particular at'eH-
ton has been given to the enormous Strains
thrown upon the cylinder castings at the front
end They are of unusual thickness 9nd deptn
The frames are AZ inches wide, ana are cut
from rolled steel slabs made by the Carnegie
Steel Company. They weigh IN the fh1sheu
state l. .l6O pounds a pair. At the ifoht 'hd
steel plate l2s inches thick extends across me
frames. and heavy bolts, passing through 'he
top frame bars in front and behind form ad"i-
tional transverse ties. The longitudinal stla'hs
usual transmitted to the cylinders throughout
the frames are largely reduced ny the use of a
casting extended from the bumbor r-beam well up
To the saddle and securely bolted to the top and
bottom front frames.
