Since 2018, the city has worked with the BNSF Railway to reduce train noise in the Old Town area with the installation of wayside horns at two locations: the railroad crossings at Pflumm and Noland roads The stationary wayside horns target their warning sounds onto the roadways where motorists need to know that a train is coming. By contrast, train horns send their sound waves everywhere, even into nearby businesses and bedroom windows.
