Orien Lightning Rail

The wondrous lightning rail system once linked the far reaches of the Kingdom of Galifar, prior to the Last War. Now the system is divided, split into eastern and western circuits. Reestablishing the conductor stone paths across Scions Sound and the Mournland is often discussed in the halls of power in the Five Nations, but formidable challenges are involved.
A lightning rail train is made up of an elemental vessel linked to a series of connected carts, all of which float about 5 feet off the ground. Each cart, similar in form to a large wagon with no wheels, has a conductor stone embedded in its underside. A corresponding set of conductor stones laid out in a line on the ground interacts with the stones in the carts to form a rail for the train to follow. Lightning arcs between the two sets of stones, accounting for the system's name. The elemental vessel at the front of the train, called a crew cart, holds a bound air elemental that propels the train along its route at a speed of about 30 miles per hour. The elemental appears as a ring of lightning encircling the crew cart while the train is in motion. A bound air elemental can move a train of up to ten carts without obvious strain, and most trains are configured accordingly.
The other carts that make up the train have various purposes. A typical train has a crew cart at each end, with two cargo carts, four passenger carts, and two lounge carts in between. Doors at both ends of each cart enable crew and passengers to walk from one to the next, even while the train is in motion. Both crew carts are identical, except that the bound elemental in one is suppressed. On the return trip, the roles of the carts and the states of their elementals are reversed.
Specialized carts of other sorts vary in configuration depending on their purpose and the degree of luxury afforded to them. Some have solid sides and roofs, while others are covered only with canvas.
