NEW YORK - (AP) - A watchdog group says only half of New York Citysubway cars were clean in a survey last fall.

A year earlier, 57 percent were deemed clean.

The Straphangers Campaign's new survey found the M line to bethe dirtiest, and the No. 6 and C lines to be the cleanest.

It blamed budget cuts at the transportation agency for thedecline. There were 43 fewer car cleaners in 2009 than in 2008 andanother 108 cleaners are slated to be cut in the 2010 budget.

The survey rated cleanliness of floors and seats.

NYC Transit conducts its own subway cleanliness survey. Itsfindings showed improvement in overall cleanliness for the secondhalf of 2009.

The two surveys use similar but not identical methodology.
