The County's public transit system, Putnam Area Rapid Transit (PART), is operated by MV Transportation and runs three fixed routes year-round in addition to a seasonal trolley in Cold Spring and a commuter shuttle to the Metro North Railroad Station at Croton Falls. Additionally, a new On-Demand/Microtransit service will replace PART 3 as of May 12, 2025. Half-Fare is available for the PART and On-Demand/Microtransit services to those who apply and meet the necessary requirements. PART Paratransit is an origin-to-destination transportation system for those Putnam residents who are unable to use the regular PART service due to a physical or mental disability. PART Paratransit operates specially modified vans to transport riders with a range of disabilities, including those who use wheelchairs.
