There wasn't much time, given you could see the train leaving soon after. Okay, another possible edit - but I bet she'd have run half way down the train to board and held things up even more.
That and a 390 presumably taking a while to open/close doors, so with the doors already shut just reopening and closing them again would have definitely caused a delay.
