The main gathering space of Cleveland Union Terminal, which opened in 1929, was the Steam Concourse, so named because it was where passengers descended to board the mainline steam-powered trains. This rendering uses a little artistic license to make the concourse a bit grander than it really was, but it was, nonetheless, an impressive space. Natural light from the skylight helped conceal the fact that the concourse was essentially an underground room. This view looks eastward toward Public Square. (Sherwin-Williams Company)
