Public Transit (In)accessibility in Boston

See this article from the Boston Herald, which begins:

Despite a lawsuit and repeated complaints from disabled passengers, the MBTA is failing to maintain escalators and elevators that continually break down, denying access to thousands of people throughout the subway system, a Herald review found.
During the past week, elevators were found to be out of service at such critical hubs as North Station and Downtown Crossing, while escalators were closed down at stations along nearly every subway line in the city. Some of those facilities have been shut down for weeks, advocates for the disbaled say.
``They are essentially thumbing their nose at the Americans with Disabilities Act,'' said Rob Park, a disabled passenger who says he broke his leg Feb. 11 when a broken elevator at an Orange Line station forced him into the street to get to another station.
``The ADA was filed in 1990. That's 15 years ago,'' Park said. ``Why are we still having these issues?''
