Oh yeah, I've got a question fer ya. I know that suppression is used to reset penalties. What exactly does it do to airflow? Had a DP train leaving the yard the other day and whoever tacked the power on left the last unit in suppression and did not cut the trainline in (scenario: DP coal train remote power nearest the train was a dash 9 last unit was I think a dash 8 NS unit MUed to the Dash 9 the dash 8 was left in suppression and trainline not cut in to it. Brakes were set up and the crew couldn't make any speed leaving, they may have stalled. I attached to their crew and found the closed angle cok and that the auto was in supp.) Just curious what supp. does......
