To solve the problem of the passenger station, the Van Sweringens purchased more rights-of-way that gave them access to the area below the southwest corner of Cleveland's Public Square. Again, the Van Sweringens planned another city within a city to solve their rail dilemma; the result was the Union Terminal Complex, a mix of high-rise offices, shopping, and hotel aboveground, with a train depot and rapid station below grade. The centerpiece of this massive complex was named Terminal Tower, which was the second tallest skyscraper in the United States at the time of its completion.
