This would have added a second side platform to the south of the southernmost track, directly against the trolley terminal. The island platform would have been demolished to make room for the fourth track; alternatively, the fourth track would have been constructed adjacent to the southernmost track, resulting in a 2 side-platform, 1 island-platformed station, similar to the IRT platforms at Atlantic Avenue-Barclays Center.
