However, the lack of routine whistles will mean much quieter days and nights for residents near the affected railroad tracks.

"These horns carry a long distance," Uresk said. "This is a real positive thing."

In fact, he said he's had more calls about this issue than anything else over the years. Most engineers are pretty good, but he said some tend to lay extra long on the horns.

In Woods Cross, train horns regularly blow at the 1500 South and 500 South crossings. Some residents can also hear the horns from the nearby 2600 South crossing in North Salt Lake.

Layton will also benefit with its five railroad crossings in the city.

Overall, there are 43 at-grade crossings over the 44-mile FrontRunner distance. FrontRunner will begin service on Saturday.
