The invention discloses an air duct system and a railway vehicle, the air duct system comprises an air conditioning unit, a fresh air inlet device and a main air duct, the fresh air inlet device comprises a fresh air grille and a fresh air duct, the outer end of the fresh air duct is an air inlet, and the inner end of the fresh air duct is an air outlet; the air inlet and the air outlet are communicated through a channel which is bent upwards or bent, a water baffle is arranged in the channel, and air passing openings are formed between the edges of the two sides of the water baffle and the side walls of the channel. The main air duct is of an integrated structure integrating an air supply duct, an air return duct and a waste exhaust duct, and on the cross section, the air supply duct is located in the middle; the air return cavities of the air return duct are located on the two sides of the air supply cavity and provided with slopes inclining outwards and downwards from the top. Waste exhaust cavities of the waste exhaust air duct are located on the two sides of the air supply cavity and located below the air return cavity. The air duct system is particularly suitable for a narrow-section vehicle body, and the technical problems of an existing air duct system can be effectively solved.
