The breaking down of components into 'threes' figures heavily in the building, from three separate programmatic elements to the main building being broken down into three sections. Having the elevation drop on either side to give it an ABA rhythm breaks the main building into three and the groupings go further. There are three very large arched windows with the main entrance set at ground level in the center. At ground level there is also a grouping of three smaller windows set to either side of the entrance under the large arched windows as well as a grouping the same size to either side. Vertically, the elevation is also broken into three main components: the ground level, which is given a human scale with the overhang, and included smaller windows and entrance; the second level is the tallest, and includes three large arched windows; and the third grouping, a relatively simple frieze, cornice and parapet. The plaster ceiling in the waiting room is also broken into three sections by two large beams and unity is drawn from outside to inside by the dentil detail in the plaster and on the cornice. The interior also follows the same hierarchy as the exterior by having changes in the wall treatments. The marble makes a break at what seems to be traditional ceiling height to give the retail space a human scale, while the rest of walls are pure marble all the way the ceiling which makes the third part. The concourse, which is still in the main building but acts as a transition to the area underneath the tracks, has a vaulted ceiling broken in the three separate elements.
