Local Students Celebrate National Space Day

Friday May 4, 2018

May the 4th be with you!

Today, fifth graders from Castelar Elementary School in Chinatown learned how Metrolink is harnessing space age technology to make its trains safer here on earth. On National Space Day students learned about Metrolink’s Positive Train Control (PTC) system that uses satellite guided GPS to help prevent train collisions and other incidents.

Students were given a hands-on demonstration of PTC on simulators used to train Metrolink train engineers.

In June 2015, Metrolink became the first railroad in the nation to have PTC operational on all its trains throughout its six-county territory.
