I know that there hasn't been so much talk of the NEC New York, because it has gotten "older," but I have some kind of problem with the ACSES system in the ACS-64. At two spots, the speed system just goes down from 60 (or so) to 45 and then 30. But when I'm cruising at 60, I don't get any warnings or indications. That there will be a new speed, and the penalty brakes just apply. Like it would give me penalty warnings at normal speed changes, but with these two, it just fall straight down to 45, and then 30. The incident was noticed on the service from Washington D.C. - Boston (Newark Penn - New Rochelle) 00:55. When nearing the last station, at some point the train would just stop, and also down in the tunnels. I don't know what to do..
