Off Limits s01e06 "Buffalo"

Don travels to frigid Buffalo, New York in the middle of winter to investigate the abandoned and haunted Buffalo Central Station and visits a five-story health castle-like resort that detoxified its guests with shock treatments. He also discovers an old tunnel system from the early 19th century, gets access to a 100-year-old powerhouse run by the direct current transformers of Nikola Tesla, and explores concrete grain elevators that line the Buffalo River.
