RBRX 18533, one of three former GO Transit F59PHs on short-term lease to Metrolink while they cycle their own diesels out for installation of PTC equipment, leads Metrolink train 688 through Santa Fe Springs, California, on October 22nd, 2013. This particular train set operates from Riverside to Laguna Niguel, then to Los Angeles, back to Riverside (via Fullerton), then down to Laguna Niguel one more time, then out to San Bernardino and, from there, to Los Angeles a second time. After a short layover at Taylor Yard, it departs L.A. again heading to Irvine, then back to L.A., and finally back to Riverside. (That's a busy day!) RBRX 18533 is the former GO Transit 533, and it is painted for a proposed commuter operation in Michigan.
