There are many advantages in con-
nection with the operation of the road
by electricity. Our electric locomotives
will be designed to pull our regula-
ton load of 1900 tons or a one per
cent grade. When we strike the two
per cent grade of the mountains, an
other locomotive will be added. These
locomotives will be designed for both
passenger and freight service, so YOU
will see there is great economy here:
it will be necessary to have but one
type of locomotive for all the work on
all the grades.
THE current will be delivered to us
from the power plants as three-phase
and at a voltage of 100000. Rotary
transformers will change it, every 16
or 20 miles, into a current of 2.4oo
volts for distribution over the trolley
wire. This distribution of W will
be the best protection we can have
against accident, n will insure the
regular and continuous operation of
trains.
On Mountain Grades.
AN interesting feature of our plans
and one which | have not before made
public in any interview, is the ar
rargement for handling trains down
the mountains. M trains. of course,
will be equipped with airprakes, but
these will be only for emergency. In.
hraking the trains down the mountain
grades, the engineer will merely re-
verse his motor. You know a dynamo
is simply a motor reversed. The
changing of the motor ON the locomo-
tive, then, will transform il into a dy-
namo, which will be operated by the
weight of the train as il descends the
mountain. This will generate the same
quantity of electricity rs the motor
would consume in pulling the same
train up the grade. This current viii
be transmitted to the trolley wire and
will reinforce the current there for
pulling trains up the other side of the
hill. The retarding force of the motor,
reversed, will act as a brake upon the
train.
An Important Item.
"An ordinary locomotive Of the
steam type can run only 100 or 1875
miles before it is necessary to take it
to the roundhouse for cleaning and
overhauling. The experience of the
New York Central roa is that the
electric locomotives will run 1900
miles without the necessity for any
inspection, and it is expected that the
new type Of locomotives will run 1000
miles. This, of course, is on the tun-
mel work just outside of New York.

runs we can equal this record, but IL
we make it possible to run $50 or 800
miles without inspection, it will mean
that a locomotive can run over two d.
visions. At terminals we shall Just
have to change engineers and firemen
and run the same locomotive through.
Then there is this other considera-
tion-a steam locomotive, waiting on a
siding to meet another, consumes so
per cent of the coal that would he used
We're it in motion. When an electric
locomotive stops, it's consumption Of
power stops. This is a tremendously
big item in the business of a great
system.
The plan for heating n lighting
trains have all been worked out. They
will be simple and efficient. The work
Is to be started at once, and will be
finished at the earliest possible date.
| think, however, that three years will
be he shortest time possible for this
work. 1t Is going to be extremely in
teresting from the time it starts. for,
as l have said, this is the greatest I'M
~dertaking a railway company has ever
started upon"
Mr.. GoodnoW has been inspecting the
new work of his company in eastern
n northern Montana, and has been
as far west as Spokane. In company
with Division Superintendent Marshall
he looked over the local situation yes
terday, n met some of the business
men of the city. He went east last
night.
