I know its a long shot to get an answer but I wanted to ask anyway, do railroads use PLC's in their shops or perhaps in troubleshooting Locomotives? I know this is the more technical side of the railroad but I thought someone might know. I am currently in an "Electronics technician" course, 12 more exams and I'm finally done! It was long and rough but I'm nearing the finish line. I want to take a PLC [programmable logic controller] course and was wondering if railroads had jobs for this type of training? Again I know this is a long shot in getting an answer, but thanks to anyone if they can.
