Jerry doesn’t actually have a job working on trains - in fact, most people aren’t really sure what he does - though he would absolutely love to. He’s also… kind of an egomaniac, but in the sense that he’s trying super hard to convince himself that he’s just as great as he makes himself out to be. He parades around in a tacky, oversized conductor’s hat and claims that he works on the Excess Express.

In reality, Jerry has simply been obsessed with trains for his entire life. His house is full of highly detailed toy train models; it's one third a living space and two thirds a display for his favorite trains.

Cookie is one of his only friends.
