Platform types include are side, island and double island All the stations are labeled next to their platform location (identified by a black rectangle). Purple Line tracks are identified by purple lines and Red Line tracks are identified by red lines. From Linden to South Boulevard there are two lines representing the two tracks of the Purple Line. From Howard to Addison there are four lines representing two tracks on the outside for the Purple Line, and two tracks on the inside for the Red Line. Island platforms on the Purple Line include -- Linden, Central, Noyes, Foster, and South Boulevard Stations Side platforms on the Purple Line include -- Davis, Dempster, and Main Stations Howard and Sheridan Stations have double island platforms. Wilson Station has a single island platform in service, and two additional platforms that are not in service. All other red line stations in this corridor have single center island platforms. BOARD: Infrastructure -- Typical Cross Sections Includes four diagrams -- * At Grade - Example Linden -- Shows an at grade station with a center platform with two tracks, one on either side of the platform * Slope Embankment - Example Dempster -- Shows an embankment that is above grade and slopes on either side to ground level. The station has two tracks with two side platforms. * Wall Embankment - Example Bryn Mawr -- Shows an embankment that is retained with a wall on either side. The station has four tracks with a single center island platform between the middle tracks. -- An enlarged section is provided showing the structure with a concrete gravity wall (retaining wall) supporting the embankment. The section also calls out the layers of support from bottom to top -- Embankment Fill (Compactable Soil,) Sub Ballast (Small Stone,) Ballast (Large Stone,) Tie and Rail. * Elevated Structure - Example Sheridan -- Shows a open steel structure that is above grade. The station has four tracks with a single center island platform between the middle tracks.
