BARTy: The official history of BART's beloved mascot

There’s a lot to love about BARTy. 

BARTy is BART’s mascot, and if you live in the Bay Area, there’s a good chance you’ve seen the cartoon train out on the town (or on social media). It's got big dewy eyes, perpetually blushing cheeks, and a square head-slash-body. You can't miss the lil' guy and its smattering of accessories, be it binoculars, rainbow sweatbands, or a Ballers baseball cap. 

Since 2019, BARTy has been appearing on BART t-shirts, stickers, graphics, and signage. There are now more than 20 iterations of the anthropomorphized train – sugar skull BARTy, cricket player BARTy, Frankenstein’s monster BARTy, etcetera. 

But before all that, BARTy was a seven-year-old's sketch. 

It was winter break in 2019, and BART graphic designer Joe Lash brought his seven-year-old son to the office with him. There was much to be done in the office that day, and Lash needed something to entertain his kid while he got some work done.  

“That year, I was tasked with designing a t-shirt for employees to wear in the Chinese New Year Parade in San Francisco,” Lash remembered. “I was coming up with a bunch of concepts, and I said to my son, ‘Why don’t you draw some, too?’”  

His son got to work sketching. Every one of his designs featured a square train with a smiling face, and because it was the Year of the Rat, the seven-year-old added a rat and cat “dabbing” on top of the train. 

“That drawing didn’t make the final cut, but the square train design did,” Lash said. “That was the birth of BARTy.” 

People loved those Chinese New Year t-shirts, so the BART Creative Services team decided to try the concept again for St. Patrick’s Day. Things went totally off the rails from there. 

“At the time, we were thinking about designing a new BARTmobile, and I was working on various faces for it,” Lash said of the mini train that BART rolls out for parades and events. “I thought a kawaii-style face would be awesome for it.” Kawaii means “cute” in Japanese. It’s a popular aesthetic style that emphasizes adorableness and simplicity, often characterized by rounded shapes, big eyes, and soft colors.

A new BARTmobile never came to be, but the facial concepts Lash designed for the vehicle stuck with him. And got stuck on BARTy. 

In the years since its conception, every BART graphic designer has created many BARTys for many occasions. Part of the appeal of the character is its adaptability. Fourth of July? Add an Uncle Sam hat. Pride parade? Make BARTy dance on a disco ball. Halloween? BARTy becomes a pumpkin. 

The character has taken on a life of its own. Sometimes, you’ll see BARTy in social media videos wandering the system on a stick (unlike BART trains, BARTy doesn’t have functioning wheels and require some assistance). Other times, you might find the cartoon on BART valentines or even informational ads on trains.

“BARTy really taps into what BART means to the Bay Area,” said BART Marketing Manager Roderick McFarland. “BARTy isn’t just BART, it’s a part of the community, every holiday, every celebration—from Lunar New Year to Dia de los Muertos and 4th of July to Hanukkah. It’s about being seen, acknowledged, and valued. BART employees come from every possible Bay Area community, and BART serves every community. BARTy is a playful embodiment of that relationship.” 

People outside of BART have run with the concept, too, designing their own versions of BARTy. We invite you to do the same by downloading this printable template.
