October 27, 2025, afternoon, overcast. This is a very old-school steel truss railway bridge. From a structural mechanics perspective, its stress distribution is straightforward and easy to calculate, achievable even with pen and paper under extreme conditions, fitting the design capabilities of the pre-computer era. In the early 20th century, bridges of this type were typically railway bridges, embodying the unique industrial beauty of that era. The aesthetics of the First Industrial Revolution—and indeed the early Second Industrial Revolution—are precisely the element most lacking in contemporary Chinese aesthetic sensibilities. Modeled as the entire railway bridge.
