Re: Signal Failures by Sand Box John Sat Mar 14, 2009 6:10 pm "rail10" When there is a signal failure how can metrorail trains operate under those conditions? Proceed at speed no greater then 15 MPH on orders from central control. A common cause of signal failure is the result of low or insufficient gain in the track circuit amplifiers (loss of cab signal). John in the sand box of Maryland's eastern shore.
