If you’ve ever experienced not being able to fit onto a crowded train, you’ve probably fantasized about how nice it would be if there were twice as many trains passing through your station. Well designer Phil Pauley turned that fantasy into a concept called The Eco Drive Monorail (EDM). The EDM was designed to straddle over existing urban infrastructure like tunnels, houses, roads and other train tracks, creating an extra rail line for a train to run. Two EDM trains operating on the same monorail can act as one unit or as two separate trains and can move in the same direction or in two separate directions at the same time. Think about how such a solution could alleviate cities that have trouble keeping up with high demand at peak commuter times – ahem, NYC.
