The oil separating and filtering plant for the treatment ofthe condensed steam from the condensers on its way backto the hot well tank, is also in duplicate. Each plant iscapable of separating oil from, and filtering, 8000 gals, ofwater per hour. Oil-separating batteries operating under225 volts are used. The batteries discharge into a collect-ing tank, from which the water is led to a sand filter. Thefiltered water then passes into the hot well tank below. i68 STREET RAILWAY JOURNAL. [Vol. XXX.
