The successful performance OF the ar
ticuIated duplex compound freight loco
motive of the Baltimore & Ohio rallToau
IN helping push heavy freight trains over
the rather steep grades on the Alleghany
mountains is very gratifying TO the man
a-ement of the road, railroad experts
generally and the builders Of It
This locomotive is the first Of the Nal
let type ever built and there is no other
in the world that near equals It IN Size

a special report on its performance o.,
No locomotive IN service on any Tdl-
road has been talked about more Nldh
this one, and it Is one OF the many at

see in travelling over the section OF the
road where it Is in operation
After the close of the St Louis eXDos1-
ton, this locomotive. which IS No 2,4O0,
was brought to the ConnelIsvIlle DIVISION
of the Baltimore & Ohio railroad and put
into regular service between COnnellsville,
lockwood and Sand Patch, TO ASSIST
heavy freight trains over the noun

Used in Mountain Work.
This locomotive has made several road
trips and been in mOunta5Tp-heiper service
during the past five months ana IN TINS
time il has made about 1890 miles 1t was
designed for the purpose OF balanclng
the power of the division and TO reduce
the number OF locomotives and crews re-
quired to handle heavy freight tonnage
over the mountain districts, and thus
greatly facilitate the movement OF uaftic-
which has grown so largely during recent
years and Is growing very rapidly under
the present management OF the road.
It Is really a pair of locomotives with
one boiler which Is carried on Two sets
OF driver wheels each or which IS IlIUy-
seven inches in diameter. When IN work
ing order the locomotive weighs S34-5o
pounds while, with the tender attached.
(Which has a capacity of fifteen tons OF
coal and 1000 gallons Of water), the total
weight IS 1880 pounds, or about ly3.3Oy
pounds less than the combined total
weight Of two Of the heaviest consolida-
tion locomotives that are used for other
freight service over this same mountain
district.
While the draw bar pull behind the ten

uves is about q. 400 pounds, the draw bar

steel cars, Of about 100000 capacity tn
weight of the train that the Nc 2-f00 and
one of the consolidation locomotives can
take up the grade is about 3,210 tons con
tanned in similar cars These figures are
based on the locomotives operating at a
speed Of ten miles DeT hour under gen
orally fair conditions, and with the bis
locomotive working in compound gear.
Satisfactory Results.
From the practical performance Of this
locomotive during the past five months
ii has been demonstrated that the various
SueCial features which are combined m

Working on Heavy Grades.
Sand Patch IS about thirty-three miles
west Of Cumberland, Md, and from there
To lockwood the grade ranges from l.;

motive operates is nine degrees while on
the heaviest grade there Is reverse cur

In number of test trips that have been
made with the Mailet locomotive, one
engineer and one fireman have been used
To- operate IT. with the result that there
were no failures or delays on account OF
the locomotive
