The Cedar Avenue Substation for the Cleveland Railway Company was constructed in 1917 in Cleveland, Ohio. It was the first automatic substation for the company in the city, located across the street from the Cedar Avenue power plant, which was then at the time the largest non-condensing direct-current plant in the United States.
The new Cedar Avenue Substation featured eight rotaries, each 1,500 KW in capacity with 60 cycle 514 RPM Westinghouse machines. 2 With the installation, the railway company boasted 20 rotaries of 1,500 KW capacity each and two with 1,000 KW capacity, with controlling apparatus sourced from General Electric. The transformers were air-cooled Westinghouse 550 KW ampere units installed without shells. The company opted to use smaller capacity rotaries instead of four 3,000 KW units due to redundancy.
The exterior was finished with press brick adorned with cut stone trim in the front, with side walls built of shale brick laid in cement mortar. 2 The interior was finished with tiles.
On June 15, 1948, the Cedar Avenue Substation was closed after the adjoining streetcar line was replaced with a trackless trolley. The trolley was then replaced with buses on April 12, 1963. 4
