Reply to "Can anyone supply information on Defect Detectors and will you likely be ordering one?"

Defect detectors  will also indicate if your train is traveling too slow.  Many times our train was too long getting out onto the main coming off of restricted speed yard track to get up to track speed before hitting the detector.  The computer voice from the detector would come over the radio and indicate "defect found - speed to slow".     We had to radio the dispatcher and his response always was- "have a good day"...
