When the tracks of two railroads cross each other, or in any way connect at a common grade, the crossings shall be made and kept in repair and watchmen maintained at such crossing at the joint expense of the companies owning the tracks. All trains or engines passing over such tracks must come to a full stop not nearer than two hundred nor further than eight hundred feet from the crossing, and must not cross until signaled to do so by the watchman, nor until the way is clear.
