Metrolink received the last batch of Hyundai Rotem cars, thus completing its initiative to replace its entire fleet with safer cars. Dubbed the Guardian Fleet, these cars use new crash energy management technology that better absorb the impact of crashes through crumple zones. Metrolink ordered the new cars in response to the tragic Chatsworth crash in 2008 and the Glendale crash in 2005, which horrifically showcased the shortcomings of the existing Bombardier fleet. However, Metrolink’s work in improving safety and regaining the trust of citizens does not stop there, as the agency continues to install positive train control throughout its network and refurbish the Bombardier cars still in service.
