"In the blink of an eye" - or so the saying goes.
Trains move faster than most people realize, and in the blink of an eye the average train will have traveled 41 feet.
When you approach a railroad crossing, remember to stop, listen and look - because a train can come from either direction. Stay alert - distractions like headphones may prevent you from hearing an approaching train. If the crossing arms are down or the lights are flashing, assume a train is coming - even if you cannot see one. Never drive around crossing arms, and never stop on railroad tracks. And remember, trains always have the right of way - over cars, trucks, pedestrians, and even police cars, ambulances and fire trucks.
Don't be on the losing side of physics. The weight of a train compared to an automobile is similar to the weight of an automobile compared to a tin can. Drivers can steer out of the way of crossings - trains cannot.
