A man fell in between subway cars to his death and a woman was electrocuted by the third rail in a pair of fatal subway incidents Tuesday morning.

The first incident happened around 5:15 a.m. at the 63rd Drive/Rego Park station in Queens. Police say a Manhattan-bound E train was pulling into the station when a man, who was riding in between two cars, slipped and fell under the train. The man, whose name and age have not been released, died at the scene. Service was suspended on parts of the E, M, F & R trains for several hours afterwards, but resumed around 8 a.m.

Around 8 a.m., police say a woman jumped onto the elevated 2/5 tracks at the Simpson Street station in the Bronx. The 17-year-old woman, whose name hasn't been released, landed on the third rail, and died at the scene. Police believe that her death was a suicide. Service on the 2 and 5 trains were suspended while police investigated the incident; it resumed as of 9 a.m.

If someone you know exhibits warning signs of suicide: do not leave the person alone; remove any firearms, alcohol, drugs or sharp objects that could be used in a suicide attempt; and call the U.S. National Suicide Prevention Lifeline at 800-273-TALK (8255) or take the person to an emergency room or seek help from a medical or mental health professional.
