The direct-current locomotive has been built with electricequipment running from 50 lbs. to 80 lbs. per horse-power,while for the high-speed bipolar gearless type of motor, as illus-trated on the New York Central locomotive, the electric equip-ment is as low as 25 lbs. per horse-power. The disadvantagesof this type of locomotive are the presence of the commutatorand the limitation of voltage which it imposes. The polyphaselocomotive is built with electric equipments weighing aboutthe same as the d. c. locomotive. The disadvantages of thistype are the multiplicity of overhead wires and the small airgap of the motors, entailing greater cost of maintenance. Sin-gle-phase locomotives are built with electric equipments run-ning from 85 lbs. to no lbs. per horse-power. The disadvan-tage of this type is the presence of the commutator, which itshares with the d. c. locomotive, and the small air gap, which
