The announcement came during a press conference at the National Press Club in Washington, D.C., as the NTSB identified its top transportation safety priorities.
NTSB staff indicated, "Metrolink's leadership to implement PTC is a model for others across the rail industry to follow."
In September, Metrolink unveiled its fully equipped test train at an event hosted by Metrolink Board Chair Richard Katz and the Metrolink Board.
Metrolink is nearly 50 percent through with its implementation of the $210-million PTC program. Full implementation is on schedule for 2013.
