The 39-year-old man who jumped in front of a packed Orange Line train Tuesday evening, bringing the whole line to a standstill, was hospitalized in serious condition as of Wednesday morning, according to Metro.

The man, who lives in McLean, apparently walked to the end of the platform at Clarendon station on the Orange Line just before 5 p.m., then jumped into the path of an oncoming train, Metro spokesman Dan Stessel said. Cameras on the platform and the operator of the train indicate it was intentional, he said.
