Abstract:
A locomotive warning system includes an acoustical warning subsystem configured to emit variably directed sound. A controller subsystem is responsive to an initiation command and is configured to trigger the acoustical warning subsystem to begin a sounding sequence when the initiation command is received at a first directivity angle and to continue the sound blast sequence at increasing directivity angles for a pre-establish time and/or distance traveled.
