 Other features of the original design were a pneumatic tube system and elevators installed between the rotunda and the baggage room so that a traveler's luggage would be delivered to the lobby via early 20th century automation.Most of the railroad tracks and platforms and part of the original concourse were removed during the rehabilitation for the federal courts.A simple, three-story addition, designed by Tacoma architects Merrit+Pardini in collaboration with TRA Architects of Seattle was completed in 1992.
