Percy Brand New In Package Percy may be small but this battery powered version can move on down the track by himself! Battery Powered Percy the Small Engine can even pull passenger cars or cargo cars with his magnet on the end! Percy features an easy-to-push start and stop button, sturdy diecast metal construction, a headlight, powerful 4-wheel drive, and a free wheeling feature that allows for non-battery play. In the Thomas & Friends series, Percy is normally quite happy puffing around the yard with no particular desire for adventure in the great world outside. He is always keen to oblige, a fact of which the other engines are apt to take advantage. Battery Powered Percy requires 1 AA battery, not included. Battery Powered Percy is compatible with the Thomas Wooden Railway, BRIO, Lionel Express Track and most other wooden railway systems.
