What is a "crossbuck"?
A crossbuck is a traffic sign used at railroad crossings to indicate that a train track crosses the road. The sign usually consists of a white, X-shaped symbol with the words "Railroad Crossing" written on it. The crossbuck serves as a warning to drivers to slow down and be alert for any approaching trains. In some cases, additional signs or signals, such as flashing lights or gates, may accompany the crossbuck to provide further warning and ensure safety at the crossing.
Examples

Drivers must look for the crossbuck to know a train is coming.
