[4] For its early history, the Depot was the only public building in San Carlos and functioned as the town's first community church, library, and post office.

[5] The structure was retired from railway use in 1967, but Del Monte and Peninsula Commute trains continued to stop at the station's platforms.

The building was subsequently occupied by the San Carlos Chamber of Commerce and a real estate company.

It was listed on the National Register of Historic Places on September 20, 1984, as Southern Pacific Depot.

[4] The modern elevated station, opened in 1997, has two side platforms serving the two tracks of the Peninsula Subdivision.
