A train will blow its whistle in the wide-open spaces for several reasons. The whistle can be heard at a range of 1 to 3 miles under normal conditions. But, when the train approaches a crossing, it becomes far more active. It will use short and long blasts in combination to warn those approaching the crossing. Those involved with teaching and writing about Biblical prophecy are blasting their horns today in an unprecedented manner. There is a lot of noise being made for the best of all reasons. This train is near.
