Unless otherwise noted, the details provided are based on the 1988 National Register of Historic Places (NRHP) nomination form and may not reflect updates or changes to Centralia Union Depot in the interim. The long, but narrow station encompasses , and measures .
Tenino sandstone provides a base for the concrete foundation.
Breezeways separate five sections of the structure, including two annexes and the main terminal. The depot was recorded in 1912 to have red roof tiles and measured in length. At the time of the historic designation, the depot was noted to be in excellent condition with a mostly unaltered appearance.
Exterior The exterior walls are sheathed in red pressed brick, manufactured by Chehalis Brickworks, and the roofline, noted as "massive", is a
hipped and
gable structure with flared, overhanging
eaves on each section of the structure. At the time of the nomination, roof shingles had replaced the original red tiles. The symmetrical depot is divided architecturally into five units. The dominant central portion is a two-story
pavilion that houses the depot's terminal. It is fashioned with a
cross-gable that is
perpendicular to the roofline.
Pediment gable ends feature
cornices, including a
raking cornice over a
dentil frieze. The main entrance contains a
tympanum styled with a half-round
fanlight which is bordered by a brick
voussoir. The exterior wall are framed with
pilasters. Windows are
lead glass and are double, one-over-one wood sashes trimmed with a brick hood that features a
keystone. Breezeways connect to the north and south portions, described as annexes. The passageways are open but covered under a gable roof supported by
piers made of brick. The annexes feature a
hip roof and each measure approximately . Both sections contain a
bay window, additional one-over-one windows with
transoms, and a single exterior door. A
sandstone base trims the annex walls, with additional layers for a concrete sill course and a brick dentil. Brick pilasters are featured on the corners of the sections. Originally, the north section was a "lunch room"; the south annex was an express office. A paved brick passageway, included under the NRHP designation, spans from the station to the tracks and is laid out in a
herringbone pattern. File:Centralia Union Depot 01.jpg|South annex, 2012 File:Centralia Union Depot platform side 01.jpg|Platform and north annex, 2012 File:Centralia Union Depot 09.jpg|North breezeway, 2025 File:Gable 736.jpg|Gable, 2019 File:Gable 766.jpg|

Interior The terminal measures approximately . The space contains a baggage room, offices, a passenger waiting area, restrooms, and ticket booths. Additional offices are located on a second floor, accessible by a "massive and ornate wood stairway". The north and south exits to the annexes are outlined with
parapets featuring concrete
coping and brick dentils. Additional brick parapets are located in the corners of the terminal space. Doors to the lobby include transom windows. A masonry
sill and a top brick dentil frame the windows. The lobby is tall which initially contained a
chandelier. The ceiling is in a dome-arch detail and supported by classical
Greek-style columns. Molding located below the arch is painted with an intricate pattern and is considered mostly original. The ceiling, for a time, was obscured when a false ceiling was installed; the archways between the annexes were also obscured due to the alteration. Original benches, doors, and trim are oak. An original drinking fountain, as well as brass fixtures on the doors, remain. The lower portion of the interior walls are sheathed in white tile and
wainscotting coated in
enamel paint. A
terrazzo tile floor, noted to be off-white and gray in color, was original to the station and was replaced with a similar terrazzo tile during the 1990s restoration of the station. At the time of the NRHP nomination, original light fixtures remained in a hallway between the passenger waiting area and the bathrooms. The original ladies restroom was listed in 1912 to contain such amenities as a drinking fountain, a large
plate glass mirror,
rocking chairs, and a writing table. A men's smoking room on the opposite side of the hallway also contained a similar table. The north annex contains a radio room and office space; the southern section is home to the station's freight office. In 2002, the building was noted to still be heated by a boiler and radiator system. A heating plant was originally installed to warm the depot.

Remodels and restorations The first noted restoration was the removal of
dormers in 1925. The gabled features, which contained windows, were located on the main terminal roof. The original
phone booth was upgraded to multiple private booths in 1929. The
telegraph office was moved from the second floor of the terminal to the ground floor ticket booth in January 1932. In 1953, a wire bird cage to capture pigeons was built atop the depot. The birds has long been considered a nuisance to the station, requiring consistent maintenance to repair damages done by the flock. The pigeons were known to gather discarded cigarettes, some still lit, causing small fires in the
eaves where their nests were built. The first modernization of the depot began in 1961. During the project, an
acoustic tile ceiling was installed, shortening the height of the main terminal to . The ticket booth was relocated to the northeast section of the passenger lobby; the freight offices shifted to the north of the waiting area. A concrete platform replaced a wooden plank loading dock at the warehouse portion of the station. Additional redecorations of the interior, as well as upgrades to the heating system, were also undertaken. Due to deterioration, the depot was planned for a restoration in 1974. Under orders from the city to repair the "long in disrepair" structure "or else", Burlington Northern planned to build a shopping plaza in the main terminal. A restoration of Centralia Union Station began in 1994 in three phases; the project was not fully completed until 2002. The initially estimated $1.2 million effort, funded mostly by
WSDOT, included the stabilization of the structure from further deterioration, the restoration of previously removed roof
dormers, installation of a new tile roof, re-pointing the brick exterior, upgraded utilities, and new parking lots at each end of the building. The passenger walkway was also fenced as an additional safety measure next to the train tracks. Additional funds were added to the project in September 1994 to cover costs associated with supplemental planning, such as landscaping and additions included in the original renovation proposal. By 1996, costs increased to near $2.0 million. The $1.3 million second phase started in 2000 and focused on interior work. The passenger lobby was restored, with the installation of new floors and restoration of existing mill work and brass fittings. The
drop ceiling that covered the domed ceiling of the terminal was removed. Additionally, renovations were undertaken to the Amtrak ticket office, baggage room, freight room, and express building. The
HVAC system was also upgraded. An elevator was installed and approximately of pigeon waste was removed from the attic space. The architectural firm responsible for planning the restoration, Easters and Kittle of
Issaquah, were awarded the 2003 Washington State's Historic Preservation Officer's Award for Special Achievement in Historic Preservation. The Washington Department of Community, Trade and Economic Development recognized the revitalization efforts the same year, honoring the city and the depot with an Outstanding Design Project award.
Former features The Union Depot Cafe, known as the "door that was never locked", once operated at the depot since near the beginning of its opening. The diner was closed under orders by Northern Pacific in March 1933. The grounds may have contained a
water tank and a separate freight house near the roundhouse. ==See also==
