If you thought the Blast Furnace was to much work how about a Basic Oxygen Furnace (BOF) You can still run all kinds of trains in and out of it. Here is how I built mine Build a large building first then it's all detail on one side nothing on the other side and instead of filling the inside with lots of detailed furnaces I chose tracks. I will finish the crane off one day. Sorry have to go more soon. Roo. Pipes and fittings from the Hardware store !
