An air conditioning duct for a rail transit vehicle, comprising a first duct (3) and a second duct (6) mounted in sequence on the top of a vehicle passenger compartment, the first duct (3) and the second duct (6) respectively being connected to an air supply port of an air conditioning unit by means of a distribution box (4), an inner cavity of the first duct being divided into a first dynamic pressure cavity (35) and a first static pressure cavity (31) by a first partition plate (34), an inner cavity of the second duct being divided into a second dynamic pressure cavity (65) and a second static pressure cavity (63) by a second partition plate (66), the cross-sectional area of the first dynamic pressure cavity (35) and the second dynamic pressure cavity (65) gradually decreasing along the air flow direction, and the cross-sectional area of the first static pressure cavity (31) and the second static pressure cavity gradually increasing along the air flow direction. The present air conditioning duct increases the uniformity of the passenger compartment air flow organisation and also reduces the noise in the passenger compartment, on the whole increasing the comfort of the passengers travelling in the passenger compartment.
