Union Station - "Last of the Great Railway Stations"
Restoration and Preservation on the go
Known as the "Last of The Great Railway Stations", the 1939 Los Angeles Union Station was designed by architects John Parkinson and Donald B. Parkinson. This building replaced the older La Grande Station and Central Station making it the largest railroad passenger terminal in the Western United States. The building boasts Mission Revival, Art Deco and Streamline Moderne architectural styles which hold a beautiful historic presence in Los Angeles. Union Station was listed on the National Register of Historic Places in 1980. This historic building is anything but left in the dust, currently transporting over 60,000 passengers a day through the train network of Amtrak, California regional trains, Metrolink commuter trains, and several Metro Rail subway and light rail lines. Because of the specialty of historic restoration and preservation, this gem continues as a reminder of where we have come from -- as we go forward.
