I know that the UP is now going to all none talking Defect Detector's now. So why not silence the Detector's at Milepost 332.0 and Milepost 335.3? Because they do interfere with Radio Transmittions when the Dispatcher is talking to the Trains. Milepost 332.0 is on the Blair Sub and Milepost 335.3 is on the Omaha Sub. Thanks.
