Excerpt from Electric Railway Gazette, Vol. 13: July 6 to December 28, 1895 One of the interesting features of the station is the Immendorf system for regulating the feed-u ater pumps.' The apparatus works automatically; when the water reaches the proper level in the boilers the pumps are shut off, but are started again as soon as the water falls below the determined level. The feed pumps are of the Blake duplex type. The Kellam damper regulator is employed with very satisfactory results, the steam pressure varying not over two pounds. The separators are of the Cochrane type made by the Harrison Safety Boiler Works, of Philadelphia, and Bristol' recording steam and vacuum gauges are employed.
