The MTA has begun Phase 2 of Operation Track Sweep, its multi-pronged plan to dramatically reduce the amount of trash on subway tracks, and in the process improve the station environment, and reduce track fires and train delays. This second phase of Track Sweep focuses on an intensive two-week, system-wide cleaning during which more than 500 workers will remove trash and debris from the tracks at all of the system’s 469 stations – more than 10 miles of subway station track. The clean-up work on underground stations will be done at night, when ridership is at its lightest. During the day, workers will clean tracks at outdoor and elevated stations. During this phase of Operation Track Sweep, signs will be posted at each station noting the date and time that the tracks were cleaned.
