The agency began removing trash bins at 10 stations in September in an effort to reduce the subway rodent population and the amount of refuse pick-up in the stations.
It says it has resulted in a 66 percent reduction in the number of bags collected.
The expansion calls for the removal of refuse cans in 29 stations along the J and M lines.
The agency says riders have been part of the solution by taking their trash out with them.
