Quieter whistles worth pursuing

As someone who has lived for over 20 years within the range of the many trains that pass through Elk River, I read with interest the article on the testing of quieter horns. It is a step I believe the city should definitely pursue; it makes more sense to pursue this action, considering the density of homes, apartments and schools located near the tracks than to have the city consider building a round-about on a street that cannot be considered a heavily used street. Reduction of noise pollution should be a priority no matter where it originates. —Howard Kleven, Elk River
