It is reported that a number of tests of the new controlhave been made during the past three months, and thesehave shown that it saves an average of 10 per cent in theconsumption of current compared with the standard re-sistance types. No resistance is used except at the firstcontrol point, and it has even been found that the car couldbe operated without resistance at all except for the factthat after the gears are somewhat worn the absence ofresistance at the time when all motors are thrown on to theline in series causes the car to jerk. The resistance hasbeen added to provide for back-lash in worn gears. Adetailed description of this new device will be given in alater issue of the Electric Railway Journal. Another novel feature of the car is the provision for WORK OF THE SIGNAL DEPARTMENT. Pittsburgh Double-Deck Cars—Cross-Sections at End andat Center keeping all parts of the trolley pole and harp below thehigh point of the roof, which enables the trolley to pass anyoverhead structures under which the car itself will is effected by mounting the trolley harp and pole in adepression along the center line of the roof which extendsfrom a point slightly ahead of each truck center to the endsof the car. As this depression follows the center line andis only 2 ft. 6 in. wide, it does not decrease the headroomexcept within a space extending over the longitudinal seatsof the upper deck. At this point, of course, no necessityexists for full headroom because the passengers have nochance to stand upright when they are under it and thuscannot strike their heads against it. At a meeting of the Central Railway Club on May 9, apaper was presented by B. H. Mann, signal engineer Mis-souri Pacific Railroad, giving an outline of the work cov-ered by ra
