 The light track commenced with a single "back plane" that lifted empty cars to the light track at Carbondale, where they then rolled under gravity power to the mine at Archbald.The loaded cars were towed from the mine to the foot of two planes at Archbald; after the planes lifted them they coasted to Carbondale.Ten years later in 1858, additional mines were opened at Olyphant and the road was extended further.
