Pictured here is the aftermath of an embankment failure. The spring of 2011 has brought record amounts of rain to the midwest, and this rain has to go someplace. This railroad track in Ann Arbor was supported by approximately 30ft of earth and aggregate embankment. Water from rain runoff flows along side the embankment, and slowly infiltrates into the ground. However, with all the rain this spring, the water wasn’t able to infiltrate quickly enough and a pond formed. This pond of water had the strength to push approximately 2000 CYD of earth and trees onto the adjacent Plymouth Rd. It left nearly 200 ft of railroad track suspended like a roller-coaster about 25ft above the washed-out ground. Fortunately, no trains were scheduled to use the track before emergency personnel were notified and responded to the situation.
