The former Westinghouse Electric Sharon Transformer Plant is a 58-acre facility located in Mercer County, Pennsylvania. They built substation transformers there. To test them the rolled them into a sound proof room, on a rail car, to listen for hum. Lose windings would vibrate causing hum and generate damaging heat. When I was there I was told that if wanted to rent it, they would fix the 440V door system (someone took the cooper).
To give you a size perspective of this place, our tour guide, from the balcony, said "See that toy truck down there? That is a full size 18-wheeler." It took us a 20 minute walk to reach that full size truck that looked like a child's toy in this MASSIVE room.
