K64

K64 is a steam locomotive on the railway lines (Dry Dry Railroad) between Toad Town and the station at Mt. Rugged. The machine's name is mentioned on the back of the Toad Town News Flash board after Chapter 1. In Paper Mario, Mario has to take the train to Mt. Rugged in order to proceed to Dry Dry Desert. To access the train, he first must destroy a rock blocking the railway lines with Bombette. Mario is then able to use the railways free of charge.

A train similar to this appeared in Kalimari Desert from Mario Kart 64. The background music that plays while riding the train is a remix of the music from Kalimari Desert as well. It's name is also a reference to the Nintendo 64.

Trivia

 * In Paper Mario: The Thousand-Year Door, a model of K64 can be seen on a shelf in the purple house in Poshley Heights.
