Engineers and conductors for Southern California's commuter rail service are threatening to boycott new personality tests required after the 2008 Chatsworth crash.
Two railroad unions object to the the new agreement between Metrolink and its new contractor, Amtrak, because it would require crews to pass tests to keep their jobs, according to a Los Angeles Times report published Wednesday.
The current operator, Connex Railroad, did not pursue a contract extension following the crash that killed 25 people.
Union leaders say Amtrak may not be able to field qualified train crews when it takes over operations of the 500-mile system this summer. Amtrak already requires its employees to take the screening tests for safety.
Metrolink's board says it might revisit the tests, which many corporations use to evaluate job applicants.
