Do bullet trains have air conditioning?

[BrantleyFitz]

Bullet trains have air conditioning. Here is the relevant introduction: Bullet train: Bullet train, fully known as power vehicle, refers to vehicles equipped with power devices in rail transit systems, including two major categories: locomotives and power cars. Bullet trains are equipped with driving wheels, while the corresponding vehicles without driving devices are trailers. For a train to operate normally on the track, it must have bullet trains to provide sufficient traction for the entire train, but it does not need to attach trailers without power. Concept definition: The power device is the engine, used to convert other forms of energy into mechanical energy and drive the wheels, such as steam engines, internal combustion engines, or electric motors. Conversely, vehicles without any power devices and unable to generate traction are trailers. A train cannot operate independently and normally without bullet trains.
