Forget Barbie, ponies or princesses.

All little Madeline Dubois, of Nashville, Tenn., wanted for her third birthday was to ride the train.

Her excitement is infectious in the video her dad, Daniel Dubois, captured of her reaction as the train was pulling into the station.

"As little kids do, they get fixated on something," Dubois told ABCNews.com. "We used to live where we would cross train tracks a lot. She was so fascinated with them. She was like, 'I wanna ride a train,' so we did that for her birthday. We didn't know quite how she would react."

With every wide-eyed squeal, joyous gasp and uncontrollable hands-in-the-air movement she gave, her reaction turned out to be priceless.
