The Engineer drove the train to Oslo carrying Global Peace Prize recipiant Dr. Alex Miller and Jessica Wray. However, Prime Evil sent Apparitia to take over the train. She scared the engineer enough to force him to leave his post. He managed to inform the Ghostbusters, who had recently boarded the train, before he hid inside somebody's suitcase. Later on, the Engineer found another hiding place in a trunk in his engine room.
The Engineer first appeared in Runaway Choo Choo.
