A man choked a woman unconscious and then tried to rape her on a Manhattan subway train this week, police said. 

The 40-year-old victim was sitting on a northbound C train, approaching the last stop at 168th Street in Washington Heights around 9:45 p.m. Tuesday, when a stranger approached and demanded money, authorities said. 

Then he slammed her into the train car seats and strangled her until she temporarily lost consciousness, cops said.
