The cranks of the motors are connectedby a coupling rod, which again is connected to the crank ofthe middle driving axle, but the bearing on this crank is per-mitted a free vertical movement in the rod. Both sides of thatportion of the rod are linked in by bolts, the coupling rods be- connection each motor used is independently connected to theline. MOTORS The locomotive is equipped with two motors of the sametype. (See Figs. 5 and 6). Both are double motors uniting a. FIG. 5.—SECTION AND ELEVATIONS OF MOTOR ing connected to the cranks of the next driving wheels of thelocomotive. Fig. 4 is the side view of the whole locomotive, showingthe general arrangement of both the mechanical and electricparts. The total length between the buffer ends is 11,540 mm(37 ft. ioj4 ins.), the diameter of the driving wheels 1500 mm(59 ins.); that of the idle wheels 850 mm (33>4 ins.). Inthe middle of the locomotive is the motormans cab. The frontof the cab is so shaped as to reduce the air resistance when high-tension and a low-tension motor on the same axle and inthe same casing. Both halves of these twin motors have eightpoles, and accordingly the number of revolutions is 225 perminute, or when working in cascade per minute. Dur-the official tests they have repeatedly developed double their
