The Flagstaff City Council has learned that keeping the noise from trains down is going to cost nearly $4 million dollars.

The council is looking at establishing true “quiet zones” at the city’s five railroad crossings.

During tonight’s City Council work session, city staffers will present five scenarios for the council to consider.

The proposals range from installing directional horns, called wayside horns, at each of the city’s five street-level railroad crossings, to installing gates designed to act as physical barriers.
