Phase two of the project began in May 2010, when demolition work commenced on the second and third floors, previously used by Burlington Northern for division offices. Work on modernizing the baggage area, originally used as a restaurant, were also undertaken during this time. During June 2010, work also began on demolition of a 1950s addition to the building that housed the escalators and part of the Jackson Street Plaza. Demolition work was completed by September 2010. A surprise development during this phase was the removal of the suspended ceilings in early July. Crews worked over several nights while the station was mostly empty removing the over 1,600 acoustic tiles and their framing. The modern light fixtures and remaining suspended wires remained until enough funding became available to complete restoration. The final phase of the project focused on the rebuilding of the Jackson Plaza. Thirty-six geothermic wells reaching into the ground were drilled to eventually heat and cool the station. A new concrete floor was poured including seismic wall supports and space for an elevator and new ticketing and baggage areas.
