Challenges abound in the design, construction, maintenance and operation of light-rail lines in urban areas. Chief among them is controlling track-and vehicle-borne noise, an important part of maintaining the support of an agency's various stakeholders, which include commuters and the many residents and businesses - the neighbors - adjacent to the tracks. Sound Transit, which runs through the heart of Seattle, has been particularly sensitive to the effects of train-borne noise since the system was on the drawing board. |
