Gary fits the list perfectly.

Phoenix, South Bend and all the Fort Wayne stations have some current business/occupiers even if they are underutilized.

Other "large" stations, either unused, or adapted for non-rail use, all in Baltimore, Md.:

Camden Station--Babe Ruth museum? (this refers to the station proper, trains do serve truncated platforms, and the light rail system stops there, too).

Mount Royal--now an art museum, but notable for freight trains still running under the train shed outside.

President Street Station (?)--former Northern Central (?) station, later secondary PRR station, later a Civil War museum, which I believe is now closed.

Its not "super huge", but larger than the average depot,
Erie Railroad, Elmira NY:

as far as I know, its been abandoned and completely unused for many decades..

King Street Station (former GN/NP) has been the only intercity rail station in Seattle since 4/1/1971.

Union Station (former UP/MILW) has not seen a passenger train since the day before, 3/30/71, when the last UP train for Portland departed. The last MILW train (the Olympian Hiawatha) departed the station 5/22/61 (the station had opened on 5/20/11).

On 3/6/87, work began on Seattle's Transit Tunnel, which runs under Downtown carrying both buses and light rail. When opened, the tunnel was initially used only by buses, but with a provision for the future addition of what was then planned as a streetcar line through the length of the tunnel. The provision was the installation of rail tracks in both lanes of the tunnel (separate bores) during the construction process. The tunnel opened to bus traffic on 9/15/90. During the 2000's, during the planning phase for Sound Transit's new Link Light Rail system (passed in the mid 90's), the first line of which would run from Downtown to the airport, a decision had to made on a final alignment through Downtown. The King County Commissioner at the time, Ron Simms, made the suggestion that the new light rail line utilize the transit tunnel (and the provisioned tracks), rather than a surface alignment on 3rd Avenue, under which part of the tunnel alignment is located. His suggestion became the final alignment selected. The southernmost station on the transit tunnel, Chinatown/International District (one of five total), is located immediately adjacent (on the east elevation) to Union Station. Union Station, however, was not part of the design of the station for use as an embarcation point, because of its state of neglect at the time.

In the 1990's, Paul Allen (co-founder of Microsoft) bought the station through his Vulcan firm and set about restoring the moribund station. He also acquired the land immediately south of the headhouse, where the platforms (a story below street level) and the coach yard for UP/MILW were located. However, this presented a problem. Before the station was built, a gas manufacturing company (from coal, not crude oil) had built their production facility at the same location when the site was still located at the shoreline, before the massive civil works project of filling in the tideflats had begun in ernest. The gas company later relocated to the north shore of Lake Union, and their newer facility is now the well-known Gasworks Park.

However, unlike Gasworks Park, no environmental remediation had ever taken place at the site of the former pier where Union Station was later built. Hence the problem Vulcan had to deal with when it acquired the property, as an argument ensued about who was responsible for the environmental cleanup resulting from an industry that had existed 90 years earlier! The environmental remediation process did occur, and Vulcan built a pair of very-modern-looking office buildings on the site of the former platforms. (The architecture of the two multi-story structures clashes completely with the classical style of both Union Station to the immediate north and King Street right across the street to the west).

After the restoration of Union Station was complete, the building was leased for use as office space by none other than Sound Transit. So even though it no longer sees any train passengers (light rail or intercity), the station is still being used for a transit-related purpose. The waiting room is indeed leased for public events.
