In the western half of this station, the express tracks go underneath the local tracks to run along Northern Boulevard. A short distance east of here, the express tracks rise to the same level as the local tracks. To the south (geographical west) of this station, there was a single crossover connecting the two tracks. In May 2019, this crossover was removed as part of the communications-based train control installation on the IND Queens Boulevard Line, which entailed the removal of under-used interlocking towers such as the Northern Boulevard crossover.
