145th Street station (IND lines)

The 145th Street station is a bi-level express station on the IND Eighth Avenue and Concourse lines of the New York City Subway, located at the intersection of 145th Street and St. Nicholas Avenue in Harlem and Hamilton Heights, Manhattan. It is served by the A and D trains at all times, by the C train at all times except late nights, and by the B train on weekdays only.
== History ==
The station opened on September 10, 1932, as part of the city-operated Independent Subway System (IND)'s initial segment, the Eighth Avenue Line between Chambers Street and 207th Street. At this time, only the upper level of the station opened, as the IND Concourse Line was still under construction. When the IND Concourse Line opened for service on July 1, 1933, the lower level was opened.
The station has been undergoing renovations since 2017 as part of the 2010–2014 MTA Capital Program. This is because of an MTA study conducted in 2015, which found that 45% of components were out of date.

The upper level has four tracks and two island platforms. The station used to have a full mezzanine, now, the central portion is used as a police precinct. The lower level has three tracks and two island platforms. The northbound platform here is twice as wide as the station's other three similarly-sized platforms, being 39 feet wide, so that the three trackways on the lower level line up directly with those above. Escalators lead up from this level to the mezzanine, bypassing the upper level platforms.
The center track on the lower level is used to terminate B trains during middays and early evenings, when it does not run into the Bronx. During rush hours, this track is used by D trains that run express on the IND Concourse Line in the peak direction. This track is not used during late nights or weekends.
On the upper level, just north of the station, there is an open space next to the uptown local trackhttps://www.youtube.com/watch?v=MiTJoNPqjH4&t=3m31s The “bellmouth” or that open space is visible to the right at the 3:33 mark, just as the train leaves the 145th Street station (Upper level). that was a remnant of the construction of the subway and not built for a specific purpose. That open space is where the lower level tracks turn off to the IND Concourse Line. There is a hole in the floor that allows a view of the lower level.
Both levels have a trim line on the track walls, which is yellow with a black border. It's set in a two-high course, a pattern usually reserved for local stations. Tile captions reading "145" in while lettering on black run below the trim line at regular intervals. Yellow I-beam columns run along all the platforms, alternating ones having the standard black station name plate with white lettering. 
South of this station, through 135th Street, to just north of 125th Street, the line has six tracks. The express trains use the innermost pair of tracks, and the locals uses the outermost tracks. This section of the line is nicknamed “Homeball Alley” due to the large amount of switches and signals in this area.
