So much to do, so little time

摘要

It's no secret that the federally mandated end-of-2015 deadline to implement positive train control (PTC) is unattainable for most passenger railroads. In fact, the only passenger roads projected to meet it are Amtrak, Metrolink and the Alaska Railroad Corp., which operates both passenger and freight service. Passenger-rail leaders and PTC managers say several challenges are making it tough for their agencies to meet the deadline, but they're plowing ahead to get as much done as they can by Dec. 31,2015.
