*The Blue Line runs across the methane wasteland of Titan II.
This moon/satellite was discovered on the farside of Saturn, when a survey party landed, they found the whole moon was made up of the mineral " Levitatite" when brought into the light it turns blue,all the railbeds and roads are made with the ore tailings.
This ore when mixed with plain water becomes the rare metal known as " Bluelite " used in the building of star gates/portals, it produces the watery-like surface of an “Event Horizon”.

It also what causes the anti-gravity belts to work. Here we see the Blue Line Railway that runs from BlueMine to Leviton City spaceport. In the evening the deadly mist descends, so its always nice to view it from trains sealed compartments.*
