If anyone is interested, I posted up a set of steel industry rail cars. I will be posting up some photos of the finished cars when I have a chance.
Attached is a screenshot of the set. I also included a siteplan of the Carnegie Steel Works. I calculated that it should fit on a 2x4 sheet of plywood if anyone dares taking it on
I began building a 3d model of this complex but stopped because even just printing one of the furnaces would cost a lot of money and wouldn't fit as an extreme detail print.
