MILWAUKEE — After roughly 2,200 Americans were injured or killed at rail crossings last year, those behind National Rail Safety Week are again trying to get out the word about staying alert any time one comes upon tracks nationwide.

"We have over 4,200 crossings in the state of Wisconsin," said Don Vruwink, Railroad Commissioner of Wisconsin. "Our effort is to evaluate these crossings, take data about where incidents happen and try to make the most dangerous crossings safer every year."

Vruwink said four people this year in Wisconsin have lost their lives at public railroad crossings statewide, and he wants to use this week to serve as a reminder to everyone to pay very close attention to their surroundings when getting close to or crossing any railway tracks.

"We want to make sure they abide by all the signs," Vruwink said. "Half of the [train-related] casualties or accidents occur where there are crossings or lights because people don't abide by what the gates or lights are telling them to do."
