IRT Substation 13 Rotary Converter

For the past 3 years of Open House New York I’ve wanted to go to one of the MTA substation tours but failed to be able to register in time. This year the tour was first come first served so after arriving 90 minutes early I was able to be one of the first people there and get a look inside at the old and new equipment that they run out of the 53rd st subway station.  This is a 1,500 kilowat Westinghouse Rotary Converter.
