J.J. is a Cr Stiring single, that is egar to do what's right and get the job done fast.


When J.J.'s at work he takes the express, he takes up to 10 coaches! He goes so fast that he's been named "The Purple Comet". But sometimes he doesn't mind taking frieght. But occasionally he goes out racing with famous race trains, and has won 7 trophies. J.J. can't take regular coal because he'll get very sick, so he uses purple coal and Coalinel for his main fuel.

J.J. at first wasn't good at racing but then a old race train named "Steamin' Lightning showed him tricks to do, so he could keep at first place.But J.J. knows the races is just to have fun not to win, all race trains and race cars look up to him and he provide tips for competers who don't understand what it really means to race.

He's also helped Rainbow Dash understand that there's more to racing than winning and how being a good sport will make her a winner.
