An enclosed transportation vein for efficient movement of resources and pioneers. Modular! This connects to my Transportation Vein (Straight) blueprint. It provides room for hypertubes, conveyor belts and pipelines - some connection points are already available, but there's enough room inside the vein to customise your connections to your heart's content. Uses Swatch 5 and glass roofs. IMPORTANT: this blueprint will function as both a left and right turn, depending on rotation.
