. The Street railway journal . g alley. The header is supported on roller brackets fastened to the columns in the division wall, and is about 6 ft. above the floor. At the south end this main connects to the steam piping of the old station through a 12-in. reducing valve, and at the opposite end it is capped with a blank flange. Where it passes under the steel stack it is carried upward and around the hot well already referred to. Between each battery of boilers the main contains a sectionalizing valve, and behind each battery it is cross-connected to a 6-in. main carried back of the boilers which supplies steam to the auxiliary apparatus in the boiler room. Both the 12-in. main and that for the auxiliary apparatus are drained into a 2^-in. drip main which discharges into a receiver located in the basement. From this receiver a small duplex pump forces the drip into the boiler-feed mains. A lo-in. line is carried from the main steam header to each of the two turbines. 858 STREET RAILWAY JOURNAL.
