A platform sign explaining customer-operated doors on Blue Line trains of the Massachusetts Bay Transportation Authority. Unlike many rapid-transit systems where doors open automatically at every stop, portions of the MBTA Blue Line fleet require passengers to press a button to open the doors once the train is stopped. This practice dates back to older car designs and cold-weather operating considerations, helping retain heat in winter and reduce unnecessary door cycling. The sign reflects the MBTA’s continued reliance on legacy rolling stock and the need for clear, standardized instructions in stations with high passenger turnover.
