Referring to the Marienfcldc-Zossenspeed trials of electrically driven trains,made near some years ago, thebuilders of the Baden engine state thatit has proved superior in traction and■speed, and has accomplished some ofthe fastest runs ever made in Europe. Air Brake for Pittsburgh Railwray. A recent order for air brake equip-ment well illustrates the new develop-ments in this class of apparatus. The-Pittsburgh Railway Company will install20 emergency straight air brake equip-ments for motor cars with CP 21 aircompressors, and 10 emergency straightair brake equipments for trial cars fur-nished by the General Electric Com-.

The boiler is about 63 ins. aver-age diameter, and the total heating sur-face is about 2,261 sq. ft. This engine, which was built at theworks of J. A.
