ทางรถไฟสายเก่ากลายเป็นเส้นทางปั่นจักรยานสายใหม่ของคนอเมริกันรัฐมิสซูรี่

Thousands of kilometers of railroads once criss-crossed the United States, carrying the freight that kept America's economy steaming. While trains are still important to the economy today, they play a much smaller role. Thousands of kilometers of tracks have been abandoned... including a segment of the Kansas-Missouri-Texas Railroad, better known as the “Katy,” that runs across half of the midwest state of Missouri. But, as Shelley Schlender reports from Sedalia, Missouri, that unused line became the first to find new purpose as a bike path, thanks to the Rails to Trails Conservancy.
