The trolley board is placed at the rear end of the car, itscenter being 10 ft. 6 ins. from the rear end. As the car is to beoperated in one diiection, only one bulkhead is used, which is atthe forward end. There is but one step, 11 ins. wide, having a16^2-in. riser. It is 20 ins. from the head of the rail. The car is mounted on a pair of No. 27-G. trucks. There aretwo Westinghouse No. 38-B motors on the inside of the rear insides of sills below the bolster. This is necessary, as the weightof the car without motors is 20,700 lbs. The trucks weigh 5000lbs. each. A New Method of Testing; Rail-Joints. TESTING RAIL BONDS IN BOSTON axles, with nose suspension. The forward axle is arranged for aWestinghouse compressor. The inside of the car is finished in cherry and ash. The seatsare reversible except the one against the bulkhead. The panelsare of the round-corner, seat-end type. A rather unusual featureis the covering of the roof with tin instead of canvas. There isone gong, one sand-box and a pilot on the front end of the for-ward truck. A new method of testing the resistances of rail-bond has beeninvented by R. W. Conant, electrical .engineer of the BostonElevated Railway Company, and is in use on the lines of thatcorporation. A great advantage of the device is its quickness, aswell as its accuracy, and its ability to make measurements rapidlyenables the company to make frequent tests of its rail-bonds, anadvantage which is self-evident. The accompanying engraving shows the method of its practicalapplication. The joint being tested is between the left
