Grand Waiting Room & Ticketing Concourse

Union Station, Los Angeles, CA

Union Station Los Angeles, built as the largest train station in the west, is now a transportation hub for rail, light rail, and bus service in Southern California. The restoration of Union Station is part of an overall renaissance for downtown Los Angeles. EverGreene has complete three projects at the Union Station to date. The first project was to fabricate and replace broken acoustic tiles on the interior walls and clean all the surfaces. The second include cleaning and repainting the exterior “Union Station” lettering above the entry canopy. The third project was the restoration of the ceiling.

EverGreene conserved, cleaned, repaired, duplicated, and restored many of the acoustic tiles in the massive 11,200 square foot Grand Waiting Room, the 16,800 square foot Ticketing Concourse, and the Entry Vestibule.

Many of the acoustic tiles which were fabricated out of calicel, an expanded stone aggregate, had deteriorated and needed to be replaced. Calicel however is no longer in use and no formula was available to recreate the acoustic dampening material.

EverGreene’s plaster craftsmen, technicians, artists, and conservators collaborated to develop a sample tile to replicate the original color, texture, aggregate, and thickness of the original tile. Many samples were developed using additives that ranged from pumice to household materials and a mock-up was installed prior to deciding on the proper formula. In all, more than 232 replacement tiles were cast on-site and the remaining wall tiles were cleaned or repaired. Once the cleaning and repairs were completed, the new tiles were virtually indistinguishable from the historic.
