The Lake County Sheriff’s Department is partnering with Operation Lifesaver to promote safety around tracks and trains during Rail Safety Week, September 19-26.

In 2022, Operation Lifesaver (OL) is celebrating 50 Years of Rail Safety! Since Operation Lifesaver’s inception in 1972, collisions at railroad crossings have dropped by 84%. But there is more work to do.  According to Operation Lifesaver, every three hours in the U.S., a person or vehicle is hit by a train. More than 50% of collisions with trains occur at crossings equipped with lights and/or gates.

We can all do our part to #STOPTrackTragedies. 

Adults can take the rail safety pledge at https://oli.org/pledge/adults.

» Pedestrian railroad incidents are a leading

cause of death on railroad tracks.

» Walking and camping close to railroad tracks

is dangerous and illegal.

» Trespassing on railroad tracks and property

is the leading cause of rail-related deaths in

the U.S.

» Trains are quieter and faster than you think.

» Always expect a train. Trains can run on any

track, at any time, in either direction.

-Sheriff Oscar Martinez Jr.
