counter was formerly located on the mezzanine level of Downtown Crossing station (outside fare control) under Winter Street east of Washington Street. On August 13, 2012, the MBTA combined customer services (formerly located in a booth at Back Bay station) into the Downtown Crossing location as the "CharlieCard Store". When opened in 1979, only the north half of the tunnel width was open to pedestrians. In 2017-2018, both halves were renovated to create a wider, better-lit passage.
