30. The engine bell must be rung when an engine is about to be moved; while passing through tunnels; while approaching public crossings at grade, beginning sufficiently in advance to afford ample warning, but not less than one-fourth mile before reaching such crossing, and continuing until the engine has passed over the crossing; and otherwise when necessary as a warning signal.
