feet away from the platform edges for safety and to provide space for tactile warning strips. These columns will be supported by 45 new foundations. A plaque describing the history of the station was installed underneath the replicated Knickerbocker lintel. At Times Square, a new and platform was built atop the trackways of tracks 2 and 3, the former express tracks of the original subway. The platform will extend to the east, and will be flanked by track 1 on the south and track 4 on the north. Passengers at Times Square are no longer able to board trains on track 1 from the south, as the track would be cut back a few hundred feet to the east, and as a portion of the area used for boarding will be used for the reconfiguration of the fare control area for the entrance leading to the southeast corner of 42nd Street and Broadway. Passengers are also no longer able to board trains on track 4 from the north; extending the platform to the east allowed for the abandonment of the platform currently serving trains on track 4, which is on a very sharp curve and has gap fillers to bridge a large gap between the platform and trains. This platform will be converted into employee space.

As a result of the changes, dwell times will slightly be reduced at Times Square. As part of the redevelopment of One Times Square, a new entrance with a glass canopy will be built. A new elevator to the building's observation deck will be installed and maintained by Jamestown Developers. The entrance will replace the exit to 43rd Street and will lead to the west side of Broadway between 42nd Street and 43rd Street, as well as a previously closed exit to the northeastern corner of 42nd Street and Seventh Avenue. The space currently used by passengers heading to and from the 43rd Street exit or to and from trains on track 4 will be placed outside of fare control for this new entrance. The portion
