MTA’s Flatbush-Empire Substation

I took another tour with New York Transit Museum today. This one of the Flatbush-Empire Substation, formally known as Old Prospect Park Substation. It was constructed in the early 1900s to originally provide power for Brooklyn trolleys and then was used to provide power to the subways. Sadly, the substation sits right above where the Malbone Street disaster occurred, where approximately 100 people lost their lives in 1918 when an untrained conductor was operating a subway train during a labor dispute. The substation played a role in the disaster when the circuit breakers tripped at the station from the train accident, and the substation operator restored power to the rail thereby electrocuting any victims on the tracks because the system operators thought the breakers had tripped due to a prank by strikers.

The substation originally converted AC power from the grid to DC using rotary convertors. Now they use modern thingamajigs that are not nearly so cool looking. The downstairs of the substation has all the old unused parts, not to mention all the hazardous chemicals that had to be removed. There are capacitors where PCBs had clearly been removed, and other places painted with a white sealant after asbestos had been removed. Upstairs is where the boring gray boxes filled with modern electronics that actually do the work now are. The substation does not have a working rotary convertor by the way. The only one left owned by MTA is at Substation #13 (see that post for photos and video).
