What does the new air-conditioned train mean? Why is it called "new" air conditioner?

The new air-conditioned train is centralized power supply, that is, direct power supply is provided by adding air-conditioned generator cars or locomotives.

Because "new air-conditioned" trains are powered by locomotives, they rarely change taps halfway. When changing the faucet, the air conditioner will stop working because there is no power supply, which will cause discomfort to passengers for a long time, so some lines have introduced through trains (only changing the driver without changing the faucet).

According to the relevant documents and approval of the former State Planning Commission (now the National Development and Reform Commission), the "new air-conditioned" train is a 25G or 25B passenger car with air conditioning, and the fare can be increased by 50% on the basis of the basic freight rate of railway passengers. It should be noted that 25B cars equipped with air-conditioning equipment can only be charged according to the new air conditioner if the air conditioner is used well, otherwise they can only be charged according to the ordinary car.
