New York’s subway system is about 100 years old. Which is evident when you consider the historic look of subway stops. One issue that has some people worried is that the infrastructure that supports the subway is also a century old- as well as the technology that moves the trains. The equipment is old and hard to get parts for anymore. Humans are doing jobs such as switching tracks, etc. that is automated everywhere else. This video shows some of the technology created 100 years ago that’s still in use today. Kind of crazy.
