When People's Republic of China (PRC) was founded; There is no difference between passenger locomotives and freight locomotives. There are no seats in the passenger car, and there are seats made of wood, which is of course faster than the ox cart.

In the medium term, passenger and freight locomotives have improved, but freight locomotives have not changed much. Coal-burning and passenger-carrying locomotives are composed of two sets of engines. You can go to a tired place to change locomotives and continue pulling. The same color and green, the car is hard. There are slow, fast, direct and express trains.

In the 1990s, great changes have taken place in trains, and freight cars have also developed greatly. Both speed and carrying capacity have been greatly improved. The speed increase of passenger trains also saves a lot of time for ordinary people to travel. More importantly, the stations and trains have been improved and the service level has been improved. From opening the window to closing the train, it is not so cold in winter and not so hot in summer. From simple transportation to comfortable environment, you can get services.
