handicap ramp. >> aden pulls the handicap button on his way out of the door which causes it to close right on his father's hand. completely separated from his son it's now a race against time for aaron to get off of the train. >> i frantically tried to push the open door button and they did not open. being a father i panicked, not knowing what to do i pushed the emergency intercom button and there was no answer. >> a young woman who witnesses the incident even pushes on the outside of the door in hopes it will open. but it's no use. in a matter of seconds the train begins to pull away from the station tearing apart the father from his 3-year-old son. while aaron helplessly rides to the next train station the kind bystander pulls aden to the side and waits with him. aaron gets off at the next station and hops the return train back to main street. he takes a long, seven minutes. finally a relieved aaron is reunited with his son. >> i was overwhelmed with emotion at that point in time once i saw he was safe.
