FILE - In this Feb. 6, 2014 file photo, an Amtrak logo is seen on a train at 30th Street Station in Philadelphia. A federal appeals court has once again ruled that Congress can�t give Amtrak power to impose rail standards on other private railroads. The U.S. Court of Appeals for the District of Columbia Circuit ruled Friday, April 29, 2016, it is unconstitutional to give a �self-interested� company regulatory power over competitors , even if Amtrak is a public-private hybrid.
