An uncontrolled railroad crossing warning sign is typically yellow with a black symbol. The sign features a graphic of a railroad crossing and may include the words "RAILROAD CROSSING." This color combination is used to alert drivers to the potential danger of an approaching train without any control measures in place.
It is red and white shaped like a cross.
Any grade crossing that has no warning devices, signs, or anything... or even one that is malfunctioning has the train stop or slow down for it. A conductor will either get off and flag the crossing by stopping cars and letting the train through with a flag or a flare will be lit and cast into the roadway. The horn, of course, would be honked as normally.
The train whistle or the red warning lights flashing is the first warning signal of an approaching train on a level crossing. At many railroad crossings, the stop arm would be blocking access to crossing the tracks.
No gates, and no flashing or audible signal. However, it MAY be marked by a circular sign w/a black cross and black letters 'RR Xing' on a yellow background. or a so-called "cross-buck" old-fashioned warning sign.
The road sign is a large yellow circle with a black X across the circle. The railroad can also erect their own RR crossing warning signs which consist of a two planks of wood (or other material) configured into a shallow-X or "crossbuck" style sign. These warning signs are painted white with the words "rail road crossing" stenciled on them in black letters.
Sounds like a warning of what Americans would call a railroad crossing ahead...
A railroad crossing is where the railway tracks cross over a road. It is where a driver of a vehicle must take heed of warning lights that a train is approaching, and the driver must wait until it is safe to proceed over the crossing. In Britain, all railway crossings are either gated or have a barrier, both being automated.
The x road sign indicates a railroad crossing ahead. It serves as a warning to drivers to be cautious and prepared to stop for oncoming trains.
