There are crappy commutes — and then there is this.

A straphanger took the name of the No. 2 train a little too seriously — and spread feces all over a pair of subway cars during the Monday morning commute, riders and cops said.

The train’s conductor was alerted to the situation by riders as they pulled into the Borough Hall station in Downtown Brooklyn. The conductor then said over the intercom exactly why the train was going out of service.

“The conductor announced that we were stalled because of a sanitation and hygiene issue and then said there were feces all over two cars and everyone would have to get off and wait for the next train,” said urban planner Sarah Doughtery, who was riding to Manhattan from Atlantic Avenue. “I do appreciate the honesty.”

MTA officials said they were appalled at the incident.

“We are completely disgusted, and we have no idea why anyone would do this to their fellow New Yorkers,” said agency spokesman Jon Weinstein. “The cars were immediately removed from service and cleaned.”

Police are investigating the incident.
