The introduction ofonly 2000 kw in rotaries at this pointwill, therefore, greatly increase theflexibility of the system,. The erection and equipping of thesub-stations and power station havebeen in charge of Mr. Roehl, and have. The accompanying illustrations show plans andinterior views of four of the principal sulj-stations,namely, the Tompkins sub-station, located atTompkins Avenue and Fulton Street, which servesthe central portion of the .system ; the Halsey sub-station, which serves the eastern district; the Es-> sub-station, which furnishes power to the EastNew York district, and the Coney Island sub-station, which takes care of. the large summer ex-cursion business in that direclinn. There will bea fifth sub-station in Matbush, which has not yetbeen commenced. This station will be near theBrighton Beach line and will supply power to thedistrict now supplied by the Thirty-Ninth Streetpower station. Tiic total proposed rotary capacity ofthe sub-stations is as follows: Essex suli-station, 2000 kw;Tompkins sub-station, 3500 kw; Halsey , 7000 DIRECT-CURRENT SWITCHBOARDS, HALSEY AND CONEY ISLAND SU 1^-STATIONS been under the personal supervision of his assistant, C.
