South Side Bus Route Becomes Unlikely Hub of “People’s Economy”
CTA Route 6 operators facilitating informal exchange network; CTA investigating
By Marcus Chen | Transportation & Labor Correspondent
SOUTH SHORE — Every morning at 5:47 a.m., Keisha Williams pulls her 40-foot Nova Bus out of the 77th Street garage and begins her southbound run on the Route 6 Jackson Park Express. She’s been driving this route for eight years, knows every stop, every passenger, every pothole between the Loop and South Shore.
What she didn’t know, until recently, was that her bus had become the backbone of something called “The Tally.”
“I just drive the route,” Williams says, stopped at the 67th Street turnaround. “But folks been using the bus different lately. They don’t just ride—they exchange.”
The Tally, as participants call it, is an informal mutual aid network that has emerged along Route 6 over the past six months. Riders bring goods—home-cooked meals, repair services, childcare vouchers—and exchange them using a simple tally system: mark what you give, mark what you receive. No money changes hands. No apps required. Just a notebook that passes from stop to stop.
“It’s old-school,” says Ana Rao, an economist at the University of Chicago who has studied the network. “They’re running a parallel economy right under the surveillance infrastructure. No digital footprint. No data extraction. Just human trust operating at bus speed.”
FROM TRANSPORTATION TO EXCHANGE
The Route 6 runs every 12-20 minutes from 5 a.m. to midnight, connecting the Loop’s financial district with working-class neighborhoods on the South Side. The 31 stops—71st to Jackson—pass through diverse communities: Chatham, Grand Crossing, Woodlawn.
According to participants, the Tally started organically. A grandmother bringing casseroles to her daughter began leaving extras at stops. A mechanic offered tune-ups in exchange for home care. The notebook appeared—no one remembers exactly when—and the system formalized.
“It’s not charity,” says Denise Morrison, who coordinates childcare exchanges at the 63rd Street stop. “It’s mutual aid. Everyone contributes. Everyone receives. The bus makes it work because it’s regular. You can count on it like you count on sunrise.”
The tally system uses simple marks—vertical lines for goods, circles for services. Participants report their exchanges to stop “anchors,” who maintain the central ledger. Estimates suggest 200-400 people participate regularly, with the network processing hundreds of exchanges weekly.
CTA: “NOT SANCTIONED”
The Chicago Transit Authority is taking notice—and not favorably.
“While we appreciate community innovation, the CTA cannot sanction unauthorized commercial activity on our vehicles or property,” said spokesperson Regina Torres in a statement. “We’re reviewing our policies regarding passenger conduct.”
Sources within the CTA suggest management is concerned about liability. If someone gets sick from a shared meal, who is responsible? If a service exchange goes wrong, does the CTA face legal exposure?
“They’re missing the point,” says Rao. “The Tally isn’t happening on the bus—it’s happening because of the bus. The route creates the network topology. The schedule creates the trust rhythm. The CTA should be studying this, not shutting it down.”
THE ECONOMICS OF “BUS SPEED”
Rao, who has ridden Route 6 for three months documenting the network, published a working paper last week titled “The Inverter Curve: Efficiency and Scale in Informal Exchange Networks.”
The paper argues that economic efficiency follows an inverted U-curve relative to network scale. Small networks lack diversity. Large networks become extractive. The sweet spot—what Rao calls “the inverter peak”—occurs at human scale: networks small enough for trust, large enough for variety.
“The Tally is operating right at that peak,” Rao says. “About 400 people, 31 stops, a natural geographic boundary. It’s not efficient in the corporate sense—there’s no profit extraction. But it’s resilient. It adapts. It serves the people in it.”
The paper has gained attention in alternative economics circles. References to “Rao’s Curve” appear on academic Twitter. Several European universities have requested speaking engagements.
“It’s funny,” Williams laughs. “I got a PhD riding my bus.”
THE NEXUS QUESTION
Not everyone is celebrating. Victor Nexus, CEO of Nexus Data Systems—a South Side-born tech executive whose company specializes in “urban optimization”—published a scathing op-ed in yesterday’s Crain’s Chicago Business.
“The Tally is a charming anachronism,” Nexus wrote. “But we shouldn’t romanticize poverty workarounds. These people need integration into the formal economy, not isolation in informal networks that track nothing, optimize nothing, and leave participants vulnerable.”
Nexus proposes a different solution: the Smart Transit Exchange (STE), a blockchain-based mutual aid platform that would “modernize” the Tally while preserving its community character.
“Translation,” says Morrison. “He wants to put a meter on our sharing. Turn our community into his data.”
Rao is more measured: “Mr. Nexus represents a real philosophical difference. He believes technology should extract value and redistribute it. The Tally believes value should never be extracted in the first place.”
WHAT’S NEXT
The Tally continues to grow. Organizers report interest from communities along other routes—the 4 Cottage Grove, the 15 Jeffrey Local. A “Tally Council” has formed to coordinate across lines.
“The question isn’t whether this spreads,” Williams says, preparing for her northbound run. “The question is whether they let it.”
She pulls away from the turnaround, the 77 Hz hum of her diesel engine rising through the floorboards. In the back, two women exchange a Tupperware container for a handwritten coupon: “Childcare, 3 hours, valid March.”
Another mark goes in the notebook.
The pattern continues.
