The "Memories Museum," founded as a joint venture by St. Louis Station Associates and the Museum of Transportation, is dedicated to preserving the rich history of St. Louis Union Station, the railroads that served it and the people who experienced the romance of rail travel.

"O" Gauge model trains, railroad china and silverware, uniforms, timetables, a working model railroad and other artifacts and memorabilia from St. Louis Union Station’s glory days as a major rail hub are exhibited in the museum, along with a video theatre that showcases the restoration of St. Louis Union Station.

The Museum is free to the general public and is open during St. Louis Union Station’s operating hours.
