grades of 2per cent are encountered, yet high speeds must be at-tained. ()n the test track at Pittsburg, which is about 5■miles long, and is in reality a succession of curves, loco-motive No. 10,003 recently reached a speed of 73 m. p. h.,and it is claimed that a speed of 90 m. p. h. can easily bereached on a straight track. The complete locomotive is to consist of two separatehalves, only one of which has yet been constructed; thehalf locomotive has been found to exert a maximum draw-bar pull of 24,000 lbs., indicating a tractive effort for thewhole locomotive of 48,000 lbs. The former locomotives werebuilt for third-rail direct-current operation, while the latterlocomotive will use single-phase current from an over-headtrolley wire. Before the construction for the electrificationof the Pennsylvania terminal in New York is undertaken,it is the purpose of the Pennsylvania Railroad thoroughlyto test out the merits of these two systems.

SINGLE-PHASE DEMONSTRATION LOCOMOTIVE FOR THE PENNSYLVANIA RAILROAD now possible to report the results of tests of this locomotiveand to explain more fully the service for which it wasdesigned. The locomotive has been developed by the Westinghouseinterests in conjunction with the Pennsylvania Railroad,under George Gibbs, chief engineer of electric traction,according to the program laid out by the late President Cas-satt; it is the third locomotive built under that program.The first locomotive, which was designed as No. 10,001,was of the geared direct-current type; the second, known as10,002, was of the gearless, direct-current type. Both of as to which system willbe used will probably not be reachedbefore Jan. 1, 1908. The most striking features of locomotive No. 10,003 areits entire simplicity and the accessibility of the parts thatmay require attention. All of the main control equipmentis placed on a raised platform in the middle or the cab, oneach side of which there is a wide pass
