I've designed transit sound walls. For electric light rail, they don't need to be more
than 3-4 feet high. Most of the sound comes from the wheels on the rails, with some
from the motor, and since both are pretty low that's enough. Don't think scenic considerations will matter when they're that low; they're usually not considered
intrusive.
