This student analyzed various train car designs and identified elements they wanted to incorporate into their own train car design for a PLTW class project. Key elements included curved windows for views, an observation dome running the length of the car, cut-out windows, arched wheel details, balcony size and shape, vertical rail rods, thinner wheel spokes, and selectively painting different elements different colors. The goal was to create a realistic-looking toy train car that incorporated useful observation features.
