Interior signage at North Station, one of Boston’s oldest and most complex transit hubs. The station sits beneath TD Garden and serves as a major interchange between the MBTA Orange Line, Green Line (north branches), Amtrak Downeaster, and MBTA Commuter Rail. The current underground rapid-transit facilities date largely to the late 20th-century rebuilds, following the demolition of the original above-ground North Station headhouse in the 1920s and subsequent reconstructions tied to Boston’s evolving rail network.

The platform wayfinding reflects this layered role: subway lines, regional rail, and intercity service are all integrated into a single information system. Electronic arrival boards and map panels emphasize transfer efficiency in a station that functions as the northern rail gateway to downtown Boston and the broader New England rail network.

Haymarket Station in downtown Boston, one of the oldest transit locations in the city, serving riders since the late 19th century in various forms. The current underground station opened in 1971 as part of the MBTA’s modernization of the Orange Line, replacing earlier elevated structures that once ran through the area. The station sits at the edge of the historic Haymarket district, long associated with public markets and transportation links between downtown and Boston’s North End. The cylindrical steel columns and low-ceilinged platforms reflect mid-20th-century transit design, while the signage and lighting document decades of incremental updates to keep the station functional within one of the system’s busiest transfer points.
