On thelarge sets there are two air pumps, each of 30-in. condensers are placed below the engine room floorlevel, and immediately at the rear of each engine. Each engine is provided with steam-driven barring are capable of withstanding an overload of 25 percent for two hours, and 50 per cent for short periods. They the engines are running, the governing variation from noload to full load being 2\ per cent. The cylinders are ofhard, sound metal, the high-pressure cylinder being 17^ diameter and the low-pressure cylinder being 35 ins. indiameter, both having a stroke of 3 ft. The piston rods are4 ins. in diameter and are fitted with United States metallicpacking. The crankshafts are made of hollow Siemens-Martin steel, 12-I- ins. in diameter and 15 ins. at the wheel 36 STREET RAILWAY JOURNAL. [Vol. XX. No
