After my studies on the adverse impact of elevated train noise children’s classroom learning in a school in Upper Manhattan were published, the New York City Transit Authority became more involved in seeking out ways to reduce rail noise. I was asked to be a consultant to the Transit Authority in this undertaking. As I studied the rail noise in greater depth, I learned that rail noise could indeed be reduced, e.g. welded rail, rubber rail seats between rail and tracks, wheel truing, and track lubrication. What I also learned is the relationship between noise and proper maintenance of the system. To run a system with fewer breakdowns and disruptions, it is wise to keep the system properly maintained and noise should be viewed as a clue to potential breakdowns. Thus, keep the wheels trued and the tracks lubricated.
Now forty-five years after the publication of my first study on transit noise and learning, I read that Transport for London is being confronted by riders who say that the one aspect of their journeys on the Tubes that they dread is the noise. In April Curtin’s article for MyLondon, we learn that a research project recorded sound levels exceeding 105 decibels–that’s extremely high–on some of the journeys. As discussed in my earlier writings, this article notes that the rail squeak that passengers are complaining about causes damage to the tracks and trains. Not surprisingly, we are told, this adds to the maintenance bill.
In response to the noise complaints, Transport for London says it is carrying out regular maintenance work and “investing in new technologies to reduce noise on the Underground.” As the co-author of the book “Why Noise Matters,” written with four British co-authors, and as an individual who has examined transit noise for so many years, I offer my assistance to Transport for London as they explore ways to reduce rail noise.
