NS Defect Detector Not Working! 

This is something very much out of the ordinary for my channel! I'd firstly like to apologize for the quality not being as good as it is usually is. This was a spur-of-the-moment filming, filmed with my iPhone rather than an actual video camera.
Anyway, while listening to my scanner for fun on the evening of February 13, 2014, NS 13G had just passed the 304.4 defect detector on the Norfolk Southern Pittsburgh Line. Instead of announcing the usual 'no defects' reading, the reading went, "Norfolk Southern, Milepost 304.4, track two, detector not working." You can then hear the train crew relay the message to the dispatcher, and the NS Help Desk, who both advise the train go 30 MPH to the next detector (317.8).
While not a video of a train, it's still something unusual that you don't see everyday. It was honestly the first time I've heard any detector give a reading like this!
