How did the train change tracks?

Every track will have a movable mechanism in the invisible place, and the track will get the converted signal and gradually merge into the track that needs to be converted.

There are steel rings on the inner side of the train wheels, which are stuck on the inner sides of the two rails, which can not only restrain the train from running, but also prevent the train from derailing, especially when changing tracks.

Another function of the rim is to control the running direction of the train. If you want to change the track of the train, you can change the position of the rim. If you want to control the position of the rim, you need to use a turnout.

Extended data:

The most important machine in human history, called steam locomotive in the early days, has an independent orbit. Railway trains can be divided into freight cars and passenger cars according to their load capacity, and there are mixed passenger and freight cars.

Trains are a typical example of human transportation using fossil energy. 1804, the world's first steam locomotive was built by British mining technician Drivesk using Watt's steam engine, with a speed of 5 to 6 kilometers per hour.

Because coal or firewood was used as fuel at that time, people called it "train" and it has been used ever since. 1840 On February 22nd, the world's first real train running on the track was designed by Kangwa engineer Charlie Levisik.
