U.S. Transportation Secretary Ray LaHood today awarded a $40 million grant to the Pennsylvania Department of Transportation to eliminate delays in and out of Harrisburg on Amtrak's Keystone Corridor. The project consists of replacing aging track and signals with modern technologies. The Department of Transportation had previously funded $23 million to the Keystone Corridor to improve safety and allow future train speeds to increase from 110 mph to 125 mph. The Keystone corridor operates between New York, Philadelphia and Harrisburg and is Amtrak's fourth most heavily traveled route. Since train speeds along the route were increased to 110 mph in 2006, ridership has grown by more than 37 percent to 1,227,075 passengers in 2010.
