A railway crossing is a designated point where a road intersects with a railway track. These crossings can be marked with signs, signals, or gates to alert drivers and pedestrians of approaching trains. Safety measures are crucial at these locations to prevent accidents, as trains cannot stop quickly. There are two main types of railway crossings: active and passive. Active crossings have warning lights and gates that operate when a train is approaching, while passive crossings only have signs to indicate the presence of tracks. Proper awareness and caution are essential for everyone using these crossings to ensure safety.
