Gingerbread S-4 Compilation

What do you get when you send an engineering student home from school for Christmas break? Nearing the end of 2005 my family got to see exactly what is possible. The result of a Christmas tradition in our house and a semester of Engineering Graphics turned the kitchen into a mini Baldwin Locomotive works that turned out this replica of an S-4 Class Berkshire type with all the special trimmings. Since it was about Christmas time, it was lettered for the Polar Express. It also sported a full Walschaert's Valve Gear. Details like the coal in the tender further enhance the full effect of the model.
