Police in Hammond, Indiana say surveillance video should remind drivers about the danger of trying to beat a train.
Police are using this video as they investigate a crash that killed two children and left their mother with critical injuries.
Investigators say Edie Bolanos cut through a parking lot in an attempt to beat a train.
When she tried to cross the track a freight train hit her car and then pushed it into the path of another train heading in the opposite direction.
The impact killed Bolanos' eight and 11-year-old daughters while her two sons survived.
