Crossing DOT Number
The U.S. Department of Transportation (U.S. DOT), through its Federal Railroad Administration (FRA), uses a numbering system to identify all railroad crossings (and a few light rail crossings) throughout the United States. The U.S. DOT crossing number consists of 6 digits followed by a letter.
The U.S. DOT numbers can be queried by visiting FRA's crossing inventory website.
