Park Street is a rapid transit and light rail station of the MBTA subway system in Downtown Boston. One of the four subway hub stations, Park Street is a transfer point between the Green and Red Lines. Park Street is the fourth-busiest station in the MBTA network, with an average of 19,836 entries each weekday in 2010. Throughout the Green and Red Lines, trains labeled "inbound" are headed towards this station, Downtown Crossing, or Government Center, while those labeled "outbound" are headed away.
Park Street is located in the southwestern section of Downtown Boston, specifically at the intersection of Tremont and Park Streets, under which the Green and Red Lines run, respectively. Nearby are a number of important sites, including Boston Common, the Massachusetts State House, Emerson College, Suffolk University, the Freedom Trail, Newbury Street, and the Boston Paulist Center.
The Green Line platforms on the upper level of Park Street Station were originally constructed in 1897, making it one of the two oldest subway stations in the United States, along with Boylston station. The Red Line platforms beneath, sometimes called "Park Street Under," were constructed in 1912.
Station layout 
Park Street is a bi-level station, with the Green Line running on the upper level and the Red Line on the lower level. It is the only MBTA subway station with six tracks: tracks 1 to 4 are used by Green Line trains, while tracks 5 and 6 are served by the Red Line. The upper level has two island platforms, while the lower level employs a Spanish solution-type setup with one island platform and two side platforms.
Park Street station is partially wheelchair accessible, after renovations completed in 2004 and 2012. The Red Line on the lower level has both island and side platforms, a setup that theoretically allows implementation of the "Spanish solution" system of managing heavy passenger traffic flows. However, narrow stairways serving the center island platform impair full implementation of this system, since many impatient riders prefer to sprint up the wider side platform stairway to catch a Green Line transfer. Only the island platform of the Red Line level has elevator access.
New elevators from the surface to the westbound Green Line unpaid lobby and from the westbound Green Line platform to the Red Line island platform opened on December 21, 2012.
The elevators are as follows:
- Boston Common (in a standalone kiosk, south of stairway kiosk to the westbound Green Line entrance) / Fare gate entrance to the Green Line westbound island platform
- Green Line westbound island platform (pictured) / Red Line island platform
- Red Line island platform / Confluence of the northern end of the Green Line northbound side platform and the Winter Street passageway to the Orange Line southbound
- Middle of the Green Line westbound center platform / Passageway between the Green Line platforms
- Middle of the Green Line northbound island platform / Passageway between the Green Line platforms
Bus connections 
Although Park Street is not a major bus transfer point, it is served by two of the few MBTA Bus routes which run downtown. The 43 Ruggles Station - Park & Tremont Streets via Tremont Street route is a replacement for streetcar service that formerly ran to Park Street, while the 55 Jersey & Queensberry - Copley Square or Park & Tremont Street via Ipswich Street route provides local service to the Back Bay and Fenway-Kenmore areas.
