from Wikipedia:

The tunnel from Sedgwick Ave to Anderson – Jerome Avenue was built to NYC Elevated Railway standards. Those standards specified the clearance between the tracks and the sides of the tunnel only allowed for the "El" type open third rail instead of the covered third rail in use on the IRT Subway. The standard distance from the center of the track to the center of the El type open third rail-head is a few inches shorter than the distance to the subway type covered third rail-head. Thus, this design (flaw) prevented the line from being used in the future by standard IRT Subway equipment, and brought about the line's demise instead of being linked to the IRT Lenox Avenue Line at 148th St in Manhattan, which had been proposed by the NYC Board of Transportation in 1940.
