Where is the train with four carriages?

Generally speaking, the first four carriages on a train are located at the last position in the direction of the train. That is, the position closest to the rear of the train.

On the purchased train ticket, it is found that the seat is "plus 4 cars", which means that the car is temporarily added, and "plus 4 cars" means that the car is the fourth car temporarily added. In the case of a large number of passengers during holidays or winter and summer vacations, trains generally add carriages to increase capacity. According to the sequence number, for example, 1 car and 2 cars will be added.

Additional trains mainly existed in the era of traditional rail trains. At that time, China's railway transportation capacity was far from meeting the number of travelers, especially during major national holidays such as Spring Festival travel rush, New Year's Day, National Day, Labor Day, and so on. In view of this situation, the railway transportation management department often adopts the way of installing temporary carriages at the rear of trains to increase and enhance the train passing capacity of important nodes.
