The incredible burst of speed the Greenline T makes in Boston between Hynes Convention Center, Copley, and Arlington. These 3 stops make almost a perfect straight line where as the rest of the greenline needs its street cars for street service and twisted old tunnels. When there is not a lot of line traffic, drivers are given the go ahead to put the pedal to the metal. It doesnt happen often but boy is it a thrill feeling those big green caterpillars open up down there. During heavy delays, or a broken signal at Copley could delay you up to 20 minutes. The fastest I've ever recorded was just around 5 minutes to go from Hynes station to Arlington. That's when I decided to pay homage to the Kessel Run and thus born was the Copley Run.
