A crossbuck is a sign composed of two slats of wood or metal of equal length, fastened together on a pole in a saltire formation (resembling the letter X). Crossbucks usually are a traffic sign to indicate level railway crossings, sometimes supplemented by electrical warnings of flashing lights, a bell, or a gate that descends to block the road and prevent traffic from crossing the tracks. ==International variants== In the United States, the crossbuck carries the words "RAIL" and "ROAD" on one arm and "CROSSING" on the other ("RAIL" and "ROAD" are separated by the "CROSSING" arm), in black text on a white background. Older variants simply used black and white paint; newer installations use a reflective white material with non-reflective lettering. Some antique U.S. crossbucks were painted in other color schemes, and used glass "cat's eye" reflectors on the letters to make them stand out. Other countries, such as China, also use this layout, but with appropriately localized terms. Often, a supplemental sign below the crossbuck indicates the number of tracks at the crossing. A special kind of crossing sign assembly was introduced on an experimental basis in Ohio in 1992, the "Buckeye Crossbuck". It includes an enhanced crossbuck, reflective and with red lettering, and also a reflective plate reading "YIELD" below the crossbuck, whose sides are bent backwards in order to catch and reflect at a right angle the light of an approaching train. The experiment's final report gave the device a favorable review. However, the plate was rejected for inclusion in the 2003 Manual on Uniform Traffic Control Devices. In Canada, crossbucks have a red border and no lettering. These were installed in the 1980s shortly after English-French bilingualism was made official, replacing signs of a style similar to those used in the U.S., except the word "RAILWAY" was used instead of "RAILROAD". In Mexico, the crossbucks read "CRUCERO FERROCARRIL", a literal translation of its U.S. counterpart. Older designs read "CUIDADO CON EL TREN", meaning "beware of the train". In Argentina, the most common legend is "PELIGRO FERROCARRIL" ("danger: railroad"). Earlier crosses also read "CUIDADO CON LOS TRENES - PARE MIRE ESCUCHE ("beware of the trains - stop, look, listen") In parts of Europe, the cross is white with red trimmings or ends, sometimes on a rectangular background; in Finland and Slovenia the cross is yellow, trimmed with red. Taiwan uses two crossbucks. A version with a yellow and black cross, and one with the cross in white with a red border. A special symbol in the center indicates an electric railroad crossing, cautioning road users about excessive height cargo that may contact the electric wires. In Australia, the crossbuck is a St Andrews Cross as in Europe, but uses words and the same color as the American crossbuck. In contrast to the American "RAIL ROAD CROSSING", Australian signs say "RAIL WAY CROSSING" or "TRAM WAY CROSSING". (Most cases where a tram in its own right-of-way crosses a road do not use a crossbuck and so are regular intersections rather than level crossings.) Different countries may classify the sign differently. For example, in Australia it is considered a regulatory sign, while in close neighbour New Zealand it is considered a warning sign. Some countries, such as Australia, France, New Zealand, and Slovakia may place the crossbuck design on a "target board", while other countries quite often do not.
