Two major U.S. transit agencies are shifting their approach to organizational change by recruiting experienced transportation leaders and empowering internal teams to move faster on modernization projects. The Massachusetts Bay Transportation Authority and Atlanta’s Beltline have both promoted or hired senior executives tasked with cutting through planning cycles and delivering tangible results on aging infrastructure.
At the MBTA, Katie Choe led a cultural overhaul as chief of staff since 2023, focusing on untangling what she called “sticky organizational knots” that had slowed project delivery for years. Before leaving to become CEO of Virginia Railway Express in January, Choe worked alongside two other senior leaders, Melissa Dullea and Karti Subramanian, to reshape how the 128-year-old transit system operates. Their combined effort signals a broader recognition among transit agencies that infrastructure modernization requires not just capital investment, but organizational agility.
Meanwhile, the Beltline announced Joe Iacobucci as Vice President of Transit Innovation in February, after a months-long search. Iacobucci brings two decades of experience from the Chicago Transit Authority, where he led rail and bus modernization, delivered bus rapid transit corridors, and managed transit-oriented development programs. His appointment comes as the Beltline navigates a contentious shift in its rail strategy, moving away from a downtown light rail extension to focus on multimodal solutions across its 22-mile corridor.
Reframing Innovation as Practical Necessity
In traditional transit environments, lengthy planning and stakeholder coordination have historically protected projects from failure but also delayed implementation. Choe’s framework at the MBTA challenged that logic by distinguishing between endless planning and actionable progress. The agency faced a familiar constraint: infrastructure dating to 1897, including the country’s oldest subway tunnels beneath the Boston Common, required ongoing maintenance while meeting modern service expectations with limited public resources.
Choe’s tenure emphasized delivering results rather than perfecting plans. This shift extended to how the MBTA structured contracts, streamlined procurement, and relied more heavily on in-house expertise rather than external consultants for routine decisions. The result, she explained, was a “can-do” culture that treated innovation as essential to maintaining service reliability and supporting regional economic mobility.
The approach reflects a broader trend in public transit: agencies recognize that organizational culture and decision-making speed matter as much as capital funding. Leading transit systems worldwide are adopting integrated mobility strategies that require internal teams to move quickly across service planning, technology, and operations.
Managing Scale and Legacy Constraints
Dullea’s role as senior director of service planning at the MBTA exemplifies the operational complexity that modernization requires. Her team plans and schedules every bus route and the Red, Orange, Green, and Blue subway lines, while also determining how service adapts as the region changes. Subramanian’s digital tools team oversees the MBTA Go app, real-time signage, and web platforms that provide riders with live transit information, vehicle tracking, and closure updates.
These operational pillars must function simultaneously while the agency addresses aging assets. Red Line cars, for example, perform poorly in extreme cold, and planned service disruptions for system-wide repairs continue to strain reliability. New vehicles will eventually replace aging stock, but the transition period demands that internal leadership coordinate delivery schedules, maintenance windows, and rider communication.
Atlanta’s Beltline faces a different but equally complex challenge. Iacobucci arrives as the organization has shifted from a single transit vision-extending light rail around the entire 22-mile loop-to a multimodal approach that may include bus rapid transit, pedestrian infrastructure, and other mobility options. The 2016 More MARTA sales tax was intended to fund light rail, but the project was redirected to the Southside trail, and MARTA voted to stop work on the Beltline project entirely. This pivot has created heated debate between rail advocates and opponents, placing Iacobucci at the center of a complex stakeholder environment.
The Question of Execution vs. Consensus
Both appointments suggest that transit leadership is willing to prioritize execution velocity over exhaustive stakeholder consensus. This carries tradeoffs. Faster decision-making can reduce project delays and improve responsiveness to community needs, but it also risks alienating constituencies that expect extensive input on major infrastructure changes.
At the MBTA, Choe’s emphasis on delivering results meant that some planning cycles were shortened and some external review processes streamlined. The agency remained “remarkably willing to explore new approaches,” but those approaches had to move through an organization whose cultural norm had previously been to plan extensively in hopes of pleasing everyone.
The Beltline’s transition to multimodal solutions similarly reflects a practical choice: the agency abandoned a single 22-mile light rail plan in favor of a more flexible framework that Iacobucci will now design and deliver. Whether this approach will satisfy constituencies invested in traditional rail remains uncertain, but the leadership structure now prioritizes execution.
What Comes Next for Major Transit Modernization
Choe’s departure to Virginia Railway Express signals that successful internal reorganization at transit agencies can become a credential for broader transit leadership roles. Her successor at the MBTA will inherit a more operationally empowered organization, though the agency’s capital challenges-aging Red Line vehicles, planned service disruptions, and competing demands for limited funding-will persist.
For Atlanta, Iacobucci’s mandate is broader but less defined. The Beltline has committed to delivering “22 miles of pedestrian-friendly transit,” but the specific modal mix and timeline remain to be determined. His experience with transit-oriented development and bus rapid transit in Chicago suggests he may favor distributed, phased solutions over a single massive rail project, but the real test will be whether his team can navigate Atlanta’s fractured consensus on Beltline transit strategy.
Both examples point to a maturing recognition among transit authorities: organizational structure and leadership clarity can unlock progress on modernization that capital funding alone cannot achieve. The next phase will reveal whether faster internal decision-making translates to actual service improvements and whether these leadership models can sustain change across long project timelines and changing political environments.
