I found another article w/o a paywall.

It tells how the hospital executives went to the TVRM for inspiration. Seems to me the hospital's CEO who orchestrated the design is an exceptional individual.

"Getting the Community Excited"

"But the community also needed to see, understand, and get excited about their vision of healthcare transformation. In order to do that, they needed to do something to spark that excitement and create something unique for the community. So they visited one of Chattanooga's most iconic family attractions: the Tennessee Valley Railroad Museum. And they asked the folks at the museum, "How do we get people excited?"

"As it turns out, having a train certainly helps. They were able to work with the museum to get a steam train that was built in 1891 on permanent loan, and that is now the signature feature of the building. When people pull up to the main entrance, they're not pulling up to a hospital: They're pulling up to a train station."
