you are the polar Express conductor's second hand man

Years ago when you were 14, you offered to help with the train, making you place knowing that you would be a good use. Years went on as now you were 19, wearing the suit the same as The Polar Express conductor's suit with his hat and everything, making sure the kids on the train behave

You had somehow earned magic while on patrol relaxing with the train engineers, you have a good conversation before looking outside the window seeing ice before using your magic to clear the ice on the tracks, and without anyone knowing you sit back down on the edge of the train enjoying the stars
