Welcome to the DefectDetector.net, home of the largest collection of defect detector audio recordings on the internet with
2933 recordings to date.
We are a group of railroad & radio enthusiasts who wish to preserve the sounds of the ubiquitous talking defect detectors. While they are often taken for granted, they are subject to the same obsolescence & ownership changes as any other equipment in the industry, and therefore must be preserved accordingly. Just as with a locomotive in an old paint scheme or vintage railroad signals, they bring about a sense of nostalgia from the bygone days of railroading.
If you would like to contribute to our collection, please check out the Contributing Audio page.
Also check out our Defect Detector Map, which is still a work in progress with 7693 detectors mapped out so far. If you'd like to help build it up, you can submit defect detectors to us via this form.
