A 22-year-old Ontario man jumped in front of an eastbound Metrolink train late Thursday night and was killed, Upland Police said.

Discovery of his body, early Friday morning on the tracks near Campus Avenue, just before the Upland Metrolink station, shut down trains for about two hours, Metrolink officials said.

The conductor for Metrolink train 305 reported remains of a human or animal near the tracks at about 5:13 a.m., resulting in tracks being shut down between Rancho Cucamonga and Montclair.
