k9233 train may not necessarily have air conditioning under normal circumstances. Introduction to k9233 new air-conditioned hard-seat train: The designation "new air-conditioned hard-seat express" indicates an air-conditioned express train. New air-conditioned trains use centralized power supply, with either an attached air-conditioning generator car or direct power supply from the locomotive. New air-conditioned trains use 25G or 25B coaches equipped with air conditioning. 25B coaches can only charge as new air-conditioned trains when the air conditioning is functioning properly; otherwise, they can only charge as ordinary trains. Composition of various train series names: High-speed EMU trains (G prefix), intercity EMU trains (C prefix), ordinary EMU trains (D prefix), direct express passenger trains (Z prefix), express passenger trains (T prefix), fast passenger trains (K prefix), temporary passenger trains (L prefix), and temporary tourist trains (Y prefix).
I recently took the K9233 train, which is an air-conditioned green train. This train runs from Baoji to Chengdu, and the hard-seat carriage I was in had an air vent right above my head, making the summer ride completely free from stuffiness. However, I should remind you that the air conditioning on green trains can sometimes be unstable. On my last trip, it stopped midway, and the attendant said it was due to voltage fluctuations. I recommend bringing a small fan and a light jacket, as the air conditioning can get quite chilly when it's working at full blast. You can also see the external air conditioning units operating at the carriage connections, which are a bit noisy but tolerable.
Last month I took my grandpa on the K9233 train to Guangyuan. Since he has mobility issues, I specifically asked about the air conditioning. This train is definitely air-conditioned, especially noticeable in the soft sleeper compartments where each berth has its own air vent. However, I noticed a significant difference in cooling between the hard seat and hard sleeper sections - the hard seat carriages felt insufficiently cooled when crowded. The attendant explained it's because the refrigeration units are under the train and overloaded at full capacity. If you're heat-sensitive, better bring a folding fan. The dining car stays cool but requires purchases for extended seating. By the way, all new air-conditioned carriages now have charging sockets, which is quite convenient.
K9233 is definitely an air-conditioned train! I just took it last week. The ticket clearly printed 'New Air-Conditioned Hard Seat', and the fare was about 20 yuan more expensive than non-AC trains. When boarding, pay attention to the carriage numbers - the ones with AC have orange exteriors, while the old-style green carriages are fan-cooled. But be advised: the AC shuts off when passing through the Qinling Tunnel for about ten minutes, reportedly for train power supply safety. On my return trip, I took a hard sleeper which had an airflow adjustment switch by the headrest, with the lower berth getting the strongest cooling.
