The power equipment at the water power station in-cludes Westinghousc three-phase 25-cyclc alternators with an ag-gregate capacity of 10,500 kw. In case of accident to the water powerstation, current may be obtained from a thoroughly equipped slcanipower plant which the Georgia Railway & Klectric Co., which alsoobtains power from the w-ater power plant ordinarily, has in reservefor the operation of its lines in the city of Atlanta in emergencies.Few railways in any part of the country are so well provided Williduplicate power apparatus for maintaining the operation of the roadat all tiines.
