Lawrence stations. Red Line trains serve Argyle 24 hours a day, every day of the year; trains operate roughly every 3 to 9 minutes during rush hour and midday operation, with longer headways of up to 15 minutes at night. The station is also located a block from the 36 Broadway bus. Red & Purple Modernization Project The Argyle station is being rebuilt as part of this project. The station will receive new wider platforms, new signage, new lights, new security cameras, and new elevators, reconstruction will begin in May 2021 and will be completed by December 2024. During Stage A, the two northbound tracks and the main entrance will be closed with northbound trains using what is normally the southbound Red line tracks and southbound trains using the southbound Purple Line Express track stopping at a temporary side platform. Purple Line Express trains will continue to skip this station in both directions. Unlike a similar reconstruction happening simultaneously at Bryn Mawr, both platforms are using a single temporary entrance, as opposed to one platform using the normal entrance and one platform using a temporary entrance with no link in the paid area. Once Stage A is completed in 2022, Stage B will begin, where Argyle will temporarily close and be replaced by a temporary station at Foster Avenue.
