Record Locomotives

Six new electrical locomotives each weighing 110 tons and capable of developing 2000 horsepower continuously, hove been ordered by the New York Central Railway to supplement the passenger locomotives at present in use upon the electrified sections of the line. The locomotives are stated to have a greater capacity and higher efficiency than any other high-speed electric locomotive yet. built. The equivalent tractive effort is 14,0001b at fiftyfour miles per hour continuously, or 20,001b at forty-nine miles an hour at the one hour rating. They are able to haul 1100-ton trains in continual service between the terminal and Harmon, are capable of operating 120-ton trains in emergency service, and 1200-ton trains on level tangent track continuously a+ sixty miles per hour.

"In point of design and construction, 7 ' says the Railway Review of Chicago, "the new machines will be of identically the same type as the former ton engines having an articulated bolire with bogie gliding trucks at ends. The cab containing the engineer's compartment and that for the operating mechanism is swung between the two parts of the frame on centre pins. Each section is equipped with two-axle trucks, having n driving motor mounted on each axle. All the axles are, therefore, driving axles; and the eight motors, of the bipolar gearless type, are of the same general design as the motors on all the previous fifty-seven locomotives, and are provided with amply forced air ventilation.

"The motors are electrically connected permanently in parallel in pairs, ancf tlie pairs can be connected in three combinations — viz., series, series-parallel, and parallel. They are insulated for 1200 volts, so that if at any future time it. should be desired to operate thie locomotives on this voltacre, the pairs of motors could be changed from the parallel to series connections, and the same speeds and control combinations obtained as on 600 volts. The total weight per driving axle and dead-weight is less than flint of any other locomotive approaching thoir capacity."
