It is also notable for its Art Deco brick and limestone facade. It is significant locally under Criteria A and C in transportation, community planning, engineering and architecture.","narrative":"Located at 126 West 53rd Street in midtown Manhattan, this five-story substation was completed in 1932 to supply power to the B, D and E trains of the IND subway system. It was the largest substation in the system when built and also served as the control center, with a semicircular supervisory board on the fourth floor used to monitor electrical demand and direct the automatic substations. The Art Deco facade combines buff brick in projecting vertical planes, basketweave brick, a crenellated limestone cap, carved limestone portal frames and aluminum doors embossed with geometric patterns. Inside, a large windowless ground-floor hall retains its overhead electric crane, and some original breaker panels remain in the basement. The four original converters were removed in 1993 and replaced with solid state rectifiers, and the control operations moved out in 1994. The building is significant locally for its role in subway transportation and power engineering and for its architecture, and its exterior remains largely intact.","period_of_significance":"1932","architect_builder":null,"architectural_style":"Modern Movement/Art Deco","criteria":["A","C"],"status_note":"Still used as a substation with solid state rectifiers and to house Transit Authority vehicles; the fourth floor holds the Track Structures office.
