The roll that contained the 3-A plans is missing the elevation and plan sheet. As Ethan noted Plan 1-A and Plan 2 are the same. On the Plan 2 drawing, the numeral 2 is hand lettered of the original lettering. The Plan 1-A (Plan 2) drawing references the 3-A sheets for the exterior and interior details. Perhaps difference between 1-A, 2, and 3-A has something to do with the presence or absence of a "negro" waiting room.
