A man was critically injured last night when a train hit him while he was urinating on the track at Penrose station.
Police said the man, who was very drunk, suffered pelvic, leg and back injuries and was in Auckland City Hospital.
"It's one of the dumbest things I've ever seen," said Senior Sergeant Junior Abraham.
"I can think of better places to relieve myself."
A witness said the man tried three times to get back on to the platform when he saw the train coming but could not make it.
