Sir, On the former Chicago Division - BNSF commuter line, triple track, ACS is in use. I am reasonablely sure that certain Grade Crossing Predictor (GCP)frequencies were changed to accommodate the 60 Hertz carrier transmitted on track by wayside Cab Signal instruments. By the way on former Conrail 100 Hertz carrier was used. Whether 60 or 100 Hertz is used, the ACS codes are 0, 75, 120 and 180 pulses/minute for the cab signal aspects. So the short answer is yes, some modifications must be made.
