. >> sharis lewis is driving the train when she sees bill waving at her. >> as i'm coming in i notice on the platform but particularly this one guy that's really frantically waving and he was really on the edge of the platform. i'm like, okay. you really need to move or you're going to fall in so i initially i'm slowing down because my concentration is on him. >> when she looks down into the pit where bill is pointing she notices a shadowy, moving figure. >> like okay. that's not supposed to be there. that's a little bit too big. and i noticed there's someone in there and then, you know, automatic reflexes like, okay, you know, put the train in emergency brake and just stop. you know, the train, you don't have that automatic stop, so it was still moving and it was just like stop the train and pray for the best. and as we're coming up i can see the train go over her and that just scared me even more because i'm like, oh, god. she's not going to make it. she's not going to make it. >> i wanted to be superman and just try to hold the thing back because i could see it starting to go over
