摘要: The invention provides a method for a railroad switch for use in un-signalized (dark) territory utilizing multiple audio messages for control and communication purposes to operate the railroad switch and relay its position to incoming trains. The messages are triggered by a programmable logic controller in conjunction with a dual tone multiple frequency signals.
