N scale layout ICG Sparta District

Sorry for not being more in depth but I'm modeling in N scale.I have a space of 24 by 36 feet and will have a 3 level layout with around 475 feet of mainline without Staging,with staging it would be around 530 feet.Also will be trying to have my coal mine and my power plant have actual operating coal loader and a operating rotary dumper so lets see what happens.
