yards located lew miles west OF LIS
city of Butte At this point, new main
line trains are made up for transporta-
ton to the smelters at Anaconda. The
main line division extends through
rough, mountainous country, distance
of about twenty miles, with grades as
high as 0.3 per cent.
Between the cities of Butte and Ana.
conda, which are located at the ends OF
the electrified portion of the system,
there is considerable local traffic, both
passenger and freight. The CITY or
Butte and vicinity has population OF
about $1,000, and Anaconda about TO-
600. At Butte. the Butte, Anaconda &
Pacific connects with the Great North
ern railway, the Northern Pacific, and
the Chicago, Milwaukee & st. Paul
railroad; and, at Silver Bow, about six
miles from the city, connection is made
with the Oregon Short Line.
Fora distance OF sixteen miles, the
Butte, Anaconda & Pacific railway is
paralleled by the Transcontinental
lines of the Northern Pacific, and the
Chicago. Milwaukee &, st. Paul The
last named company has already con-
tracted for power for the operation OF
electric trains from Harlowton, Mon
tana, to Avery, Idaho, a distance OF
40 miles. sd5Sr y3a
The freight traffic consists largely
of copper ore and amounts to more
than 5000, 900 tons per year. This ma
terial is handled in steel ore cars
weighing about is tons and having a
capacity of so tons each. Trains of 80
loaded cars weighing 1000 tons are
made up at the Butte Hill Yards and
hauled by two-unit locomotives to the
Rocker yards, where 4,000-ton trains
are made up for the main line.
Eight passenger trains are operated
between Butte and Anaconda. four IN
each direction. The main line trains
we're first hauled by electric locomo-
tives on October 1st, 1913, and prompt
lv demonstrated their ability to make
better than was possible with steam
engines. Single locomotives are USED.
hauling trains of from three to five pas
senger and baggage cars.
Energy for the operation of electric
trains is purchased from the Great
Falls power company. The generating
plant is located at Great Falls, Mont.
ON the Missouri river, and has for some
time been supplying electric power for
the operating of the mines and smell
ers at Butte and Anaconda. Six hydro
electric units are installed, having a
nominal rated capacity of $1,000 XIV.
The power is stepped up to loz,ooo
volts for transmission to the trans
former substation at Butte. distance
of 100 miles. An extension OF the sys-
tenn transmits power at $4,000 Volts
to a second transformer station at
Anaconda, &c miles farther on.
The Butte station forms the center
of the extensive power system operat-
ed by the Montana Power Company.
Besides the Great Falls 100000 volt
transmission lines, there are several
so 900 volt transmissions terminating
at this point, which form part OF the
Montana Power Company's system.
These lines bring in power from the
Hauser Lake, Canyon Ferry, Madison
and Big Hole plants.
The locomotive equipment consists
of seventeen SO-ton units, fifteen for
the freight and two for passenger serv.

geared for slow speed and are operat-
ed in pairs for the main line service.
The maximum free-running speed is

The two Messenger locomotives are
of the same construction as the freight
units. but are geared for maximum
free running speed of 55 m. p. h. A
speed of As m. p. h. is made with
three passenger coaches on straight
level track.
