If the temperature in carriages is too high (or too low), what should I do?

Some passengers complained that the temperature in metro trains is too high (or too low). We have made technical methods to solve this problem. Our staffs will set the temperature in the trains in the garage according to weather forecast, so as to make passengers feel more comfortable in metro trains. If you feel cold (or feel hot) in metro trains, you could dial our service hotline 64370000, and tell the carriage number to us for further inspection and repair. (There is a “carriage number” label at the junction between two carriages. This number is 4 or 5 digits in general. The first number indicates the number of metro line.) If the air conditioner has indeed gone out of order, the driver will inform the passengers of this message through broadcast announcement, and suggest them to take the next train.
