This diagram below illustrates how a gravity plane worked. The three components of the plane are the actual lifting plane where the cars were hauled uphill, the engine house. It was usually a stationary steam engine. Some were water wheels mainly on the light track. The third part is the runout, where the cars would coast to the next lifting plane with a 1 percent downhill grade. On Moosic Mountain (Planes 8,9,10,11) these were close together because of the grade of the mountain. This should help explain the pictures on this page.
