Report it to customer service, and get the car number and exact time. They can pinpoint the offending operator on the schedule that way. It's been an agency initiative to cut that shit out with lazy operators who won't make stops because of a full car or some other lame excuse. They'll often give refund/free passes and a mea culpa, and operators do get questioned on it and punished for it when the evidence is compelling.
It's no excuse on their part if the train were running express, either, because the destination signs are required to scroll "EXPRESS" and the stop announcements sound at every station to warn people on the platform of a no-stop.
Cell phone cams and/or Twitter tend to keep them on their toes just a bit more. The operators get in real hot water when those reports go viral. Upper mgt. definitely monitors local feeds for that stuff.
