Railroad Crossing Flash Signal, Detroit, Toledo & Ironton Railroad, March 1925
Add to SetSummary
In the United States, locomotive engineers must sound a specific sequence of horn or whistle blasts when approaching most road crossings: two long blasts, one short, and one more long. Railroads frequently placed a whistle post, like this one, along the track about a quarter mile before a crossing to notify the engineer when to use the horn.
