This is,therefore, an automatic brake, as the parting of the coupler willallow the air to escape and the springs will make an emergencyapplication. The hand brake must, of course, operate in the re-verse from the ordinary, i. e., it must be pulled off to effect a re-. ELECTRIC CAR IN MUNICH lease. This brake is used on the Bergische Kleinbahn, near Elber-feld. Brussels is situated at the base and on the side of a very con-siderable hill, and the finest boulevard runs well up on to it anddown again, having thus two steep grades, each about three-quar-ters of a mile long. One of the tramway companies has a line run-ning from the Southern Railway station, through this boulevard,to the Northern station, a distance of ZTA miles, and it is operatedwith single truck cars drawing trailers. On account of the grades,a city ordinance requires that these trains be equipped with auto-matic orakes, and the road has therefore supplied the twentymotor cars and their trailers with Westinghouse automatic airbrakes, nach motor car carries on its roof two main reservoirs12 ins. in diameter and 12 ft. long, which are charged, at the south-ern terminus, by a stationary compressor situated in the powerstation not far away. They use a maximu
