Crossing Cameras

Share via

In your March 10 article about cameras at railroad crossings, you stated that a train going 79 miles per hour would take three seconds to travel the length of three football fields. At that speed it would take 7.7 seconds to do it. To travel three football fields in three seconds, the train must be traveling at 204.55 mph.
