City officials have been looking for options to the noise problem and so far have come up with two. There could be quiet zones established where the horn is not required to sound when crossing the intersection. This could cost Tualatin about $600,000. It is about the same cost to install wayside horns. These are horns that are attached to a train station and sound while the train goes by, and can reduce noise by 98 percent.
Since Tualatin, not TriMet, would benefit from the implementation of one of these possibilities, it would be Tualatin that be expected to foot the bill. Especially since the horn is a safety measure that TriMet is not so sure they want to mess with.
