A woman was killed early this morning when she tried to pee in between subway cars and fell onto the tracks.

Police say the woman, whose name hasn't been released, was urinating between two cars on a southbound 4 train around 2 a.m. Sunday morning. She apparently lost her footing and slipped and fell onto the trackbed after the train took off from Grand Central. She was declared dead at the scene.

Earlier this year, a 63-year-old man died when he lost his footing urinating between cars. Another woman died after falling between subway cars on the 1 train. Walking between subway cars is prohibited by the MTA and those who are caught will be given $75 fines.

In a separate incident, a 27-year-old man was fatally struck by a southbound D train at the Bay Parkway Station at 86th St. in Gravesend around 5 a.m. this morning. He was declared dead at the station. Police say the investigation is ongoing, but no criminality is suspected.
