Engineer and conductor unions for Southern California's Metrolink commuter rail service are vowing to boycott a new requirement for personality profile testing. The system's management says the evaluations will help prevent incidents like the 2008 Chatsworth train crash, caused by an engineer who was texting at the time. Amtrak takes over Metrolink's operation in July, and already requires such screenings when it hires new workers. Is it suitable to require conductors and engineers to take the tests? And are the evaluations effective in screening them?
