Each train runs with a three-person crew: two operators control the train from the cab at the front end of the train and handle related operations, while a third crew member is the Customer Service Ambassador. Stationed in a designated car in the middle of each train, the Customer Service Ambassador operates the doors and wheelchair ramp, makes station stop announcements, and is dedicated to assisting customers on board. Bombardier Transportation is responsible for providing train operations, taking over from CN crews in 2007 and CP crews in 2015. GO trains achieve on-time performance of approximately 95 per cent, and a refund will be provided if a train is more than 15 minutes late, with some conditions.
