ACI was founded in 1989 by James F. O’Leary and two other partners, Richard Brown and Jane Daly, all of whom held senior management positions at the Massachusetts Bay Transportation Authority. Mr. O’Leary, now the sole owner of ACI, served as General Manager of the MBTA from 1981 to 1989.

The mission of the company at its founding was to provide public and private sector clients with creative ways to manage financial and logistical challenges such as the acquisition of new rolling stock. ACI prides itself on utilizing private sector efficiencies to manage within public sector constraints. Over the years, ACI has grown into a full-service transit operator of commuter rail, heavy rail, light rail, streetcar, and bus transit services throughout the United States and Puerto Rico.

Headquartered in Boston, Massachusetts, ACI provides the full array of transit operations and maintenance services and employs a cadre of experienced managers and consultants who provide technical support to our skilled local management teams across all disciplines.

From New England to the Caribbean and from the East Coast to the Southwest and Colorado, ACI is proud to deliver high quality services that consistently meet or exceed client and customer expectations.
