THE ELECTRIC
 LOCOMOTIVES
They Are Doing Great Work Employment Broadening Afford Field for Disposi. ton of Copper

The New York Central and Hudson River railroad has recently ordered six additional electric locomotives. the most powerful of their type in the world, from the General Electric company at Schenectady. The new machines are similar to those ordered earlier in the year, being of the same type and construction. They are some. what heavier, weighing 1l0 tons. and due to recent advancement in loco motive design have materially In. creased capacity for continuous ser. vice.
 The growth in traffic and the cor responding increase in the demand | for larger and heavier train units since the introduction of electric To comotiyes in the New York Central terminal has been notable In 1906 thirty-hve GOO volt. direct current, passenger. electric locomotives were built These machines are of the 1i5-i ton type and are each equipped with four bipolar gearless motors Twelve more engines of the same type were more engines of the same type vorc placed in service In 1908. All these locomotives were designed with suffi
 cient traojve effort to operate 535.ton gross weight trains at 60 miles pei
 hour in the regular terminal serviLe.
 The ten 100-tcn electric locomotives ordered the fore part of this year are each equipped with eight bipolar, gear
 less motors. all the weight of the ma.

 weight on level tangent track contin uously, at so miles per hour. or an S0O-ton train at s5 miles per hour But the weight of the trains which 7 are being hauled out of the termina' is ever increasing steadily. and some '- of the more important trains noA Q weigh over 1000 tons. It has there e fore been deemed desirable to hay, t engines for the maximum service wit n very great continuous capacity, am h ple overload and high monetary rat - fug Th pnv.

The six ne li, electric engines will develop 2,0l O, power continuously, or 2,600 hor. Ia. power for one hour. The equivalel
 tractive effort is 14000 pounds at 0d miles per hour continuously, or 20,Ol or pounds at 49 miles per hour at Il .al One-hour rating.
