A train can't stop as quickly as a car. A train going 55 mph can take a mile or more to stop - that's about 20 football fields.
Because of their size, trains might look like they are moving slower than they really are.
In 2005, a total of 39 children ages 15 and under were killed in a train collision.
Quick Tips For Kids:
Watch for these Railroad Signs:
Many railroad crossings have a gate with flashing lights that close when a train is coming (pictured right).
Some crossings which don't have gates may have this sign (pictured top left). When the lights are flashing, a train is coming. You should wait until the train or trains have passed before trying to cross the tracks.
