We visit the Carnegie Science Center’s Miniature Railroad & Village and discover how they keep expanding the incredibly intricate 100-year-old model on this installment of Yinzer Backstage Pass. Nikki Wilhelm, manager of the Miniature Railroad & Village, takes Boaz on a tour of the model and shows us the special workshop where they store tiny cattle, build tiny trees and fix tiny trains.
