Problem sections especially at far end of routes could be switched with the necessary phase breaks being at locations being converted to 60 HZ. If there are voltage problems then the 25 HZ system may be reaching limits ? It could just be not enough high voltage capacity ?Is this a recent development? The ACS-64s have been running on the Reading side since 2018. Did the reduced service during Covid hide a problem on the Reading side?
