Stop Thomas in his tracks! Little engineers can turn Sir Topham"s Hatt to activate the bumper and stop battery-powered trains. When Thomas gets another useful assignment, they can set him back into motion again with the push of a button. Battery-operated Thomas features a working headlight, a reliable "4-wheel-drive" engine that keeps him rolling along for hours of fun and free-wheeling capabilities for non-battery play. Straight track pieces flip over to reveal a new road design for even more play options. Special traction rails give extra grip to battery-powered engines. 26-piece set includes one battery-powered, die-cast Thomas, an exclusive yellow caboose, 20 track pieces, a bridge, Sir Topham Hatt Track piece, a tree and a sign. Requires one "AA" battery (included).
