WASHINGTON (AP) — Crews are installing two large artifacts inside the Smithsonian’s National Museum of African American History and Culture.

One is a segregated Southern

Railway train car made by the Pullman Company in 1922. The other large piece being installed is a prison tower from Angola, the Louisiana State Penitentiary to illustrate the incarceration of black people in the 20th century and the practice’s links to slavery.
