The utility model relates to a track train air conditioning unit with an anti-reverse suction condensate pipe. An anti-reverse suction rubber hose is sleeved at the outlet of the condensate pipe of the air conditioning unit and a water outlet fine passage is arranged on the anti-reverse suction rubber hose. The air conditioning unit is configured on the high-speed passenger train, the reverse suction phenomenon of the condensed water of the condensate pipe for the air conditioning unit does not occur when the train runs at a high speed, and the problems of water accumulation, parts soaked with water, affected reliability and water carried during the air supply in the air conditioning unit due to the failed discharge of the condensed water are effectively avoided.
