Old Model T
The Galloping Geargrinder has been riding the rails of Carburetor County since the 1939s. The Geargrinder was light on the tracks and extra efficient at running the mail into little towns like Radiator Springs. But by the 1950s, the delivery work dried up as the semitrucks began using the new straight-line highway that bypassed the old, curving train route. Other Geargrinders ended up at amusement parks and tourist traps, but old GG prefers to continue chugging along his original line - and to keep Mater from trespassing in the tunnels!
He only appears in the beginning of Cars 2 when Mater and Lightning McQueen are riding on the railroad tracks at Radiator Springs. He is seen passing by imitating a train in a tunnel, which scares them away.
Geargrinder is painted black, with a front cowcatcher covering his chassis. He has six small wheels, all black, and a little gate that stops load from falling out of his back. He has yellow headlights, and a lantern on his side. On his roof, he has four little balls.
- Many people thought that he was just Lizzie tricking Lightning McQueen and Mater.
