Why does the train go so slowly?

Some trains are not slow, such as EMU, through express, and some express trains.

What the landlord said slowly should be ordinary express and some express trains. Some ordinary express have to give up express trains, express trains or EMU trains, so their travel time is suppressed. For example, the fastest train in Shijiazhuang-Beijing section runs on D 132, the running time is 1 hour 55 minutes, and the running time of express train K50 is 4 hours and 46 minutes. The same journey has different running time.

Train operation is also related to the weather, and the weather is also related to the speed of the train.

The operation of the train is also related to the terrain. For example, the fastest train in Xi 'an-Chengdu section of 842km runs at T7 12h49, and the slowest train runs at 2 129 18h 03. This is related to the terrain. If the same distance is in the Central Plains, the express train won't run that long. In the Qinling Mountains, the speed limit of trains is limited and there are many bends.

The operation of trains is also related to emergencies, and sometimes they have to stop temporarily.

If you don't want to waste too much time on the train, take the express train or EMU to save time.
