(DNAINFO)  Nicole Levy — You’ve probably seen this poster in the subway: “Trash contributed to 563 track fires in 2013,” it reads, “resulting in over 7,200 train delays.”

According to a new subway “trash tracker,” brought to you by WNYC’s data news team, the dirtiest station in the city is the 138th Street stop on the 4/5 line. Over the 12 months ending in June 2014, the Bronx station was cleaned exactly zero times.

That’s 17 fewer times than the MTA’s target number of cleanings per year. The MTA aims to dispatch a crew to clean the tracks at each underground station every three weeks.
