Harmful transit noise can be reduced

I recently learned about another group of people being subjected to the harsh and dangerous noises emitted from a railway. In this case it is the Squamish Nation community in Vancouver whose lives are being disrupted by engine noise, engines idling in the middle of the night and early in the morning, and 100 decibel whistle blows at night at a protected crossing. In response to these complaints, the Canadian National Railway has commented that “there will always be some noise associated with operations.” The Railway goes on to say that it has made efforts to minimize their operations.

First, let me note the research that has demonstrated that noise is harmful to health and well-being and this includes railroad noise. Second, having been a consultant to the New York City Transit Authority on rail noise and knowledgeable about the underlying causes of rail noise, I feel comfortable in wondering whether the Canadian Railway has done everything it could to lessen its system noise. This is underscored by the railway simply saying efforts have been made to lessen noise without citing examples. I would also venture to assume that the railway might believe that reducing noise could be costly. In fact, by reducing noise the New York City Transit Authority actually saved money. The building of less noisy traction motors for its trains resulted in a more efficient motor that would last longer and smoothing the rails didn’t just lessen noise, it placed less stress on the city’s aging structure where stress can lead to increased breakdowns.

It has been over forty years since my first transit noise study which found that children in classrooms exposed to passing elevated train noise had lower reading scores. Yes, we were able to remedy the noise of the passing trains and the children’s learning improved. Now all these years later, I still find that individuals are being exposed to harmful transit noise and the agency in charge appears to accept the idea that the people living near the noise have to learn to live with it.

San Jose tackled two noise problems in one meeting

In San Jose, California, the City Council recently considered two separate community noise issues in the same meeting: leaf blowers and train noise. Either the Council members are brave, because they’re willing to take on two typically nasty and intractable battles at once, or they were in for a nightmare meeting they didn’t anticipate!

Read the San Jose Spotlight article above closely and you’ll see that California actually has some tools available to regulate noise that many other regions of the U.S. do not, such as the California Air Resources Board and a statewide cap-and-trade program. Either of those programs could fund a “buy-back/Buy-Quiet” program that would remove polluting gas-powered leaf blowers and other gas-powered outdoor maintenance equipment and substitute electrical alternatives. That could accelerate the state-wide regulation of small gas-powered devices. In fact, California is far ahead of the rest of the country in regulating this equipment, with about 70 cities in the state having already addressed this problem

According to the San Jose Spotlight, Sunnyvale, Los Gatos, Los Altos, Palo Alto, and Mountain View have already banned gas leaf blowers and roughly “70 cities across California have some restrictions on gas leaf blowers, including Los Angeles, South Pasadena, Santa Barbara, Malibu, Beverly Hills and West Hollywood.”

What about train noise? The train-noise issue is entirely separate. But it turns out that the regulatory agency did NOT consult with local neighborhoods before they increased night-time train schedules. So San Jose caught the agency on a technicality.

Either way, this must have been an interesting City Council meeting in San Jose, and we wish the city’s citizens good fortune!
