I think by "train without wheels" you may be referring to it
In July 2021, the 600 kilometers per hour high-speed maglev transportation system developed by CRRC was mass-produced in Qingdao. This is the world's first high-speed maglev transportation system with a design speed of 600 kilometers per hour.

我认为“没有轮子的火车”你可能指的是它
2021年7月,中车研发的时速600公里高速磁浮交通系统在青岛量产。这是世界上第一个高速磁浮交通系统,设计时速600公里。


In 2022, this maglev train exhibited at the German International Rail Transit Technology Exhibition.
In 2023, this maglev train exhibited at the World Manufacturing Conference.

2022年,这款磁浮列车在德国国际轨道交通技术展览会上展出。
2023年,这列磁浮列车在世界制造业大会上展出。

It is not a new thing, at least it has been around for 2 years.
It is a complete solution and requires a dedicated track to operate. This means that it is not a "train" that can run on ordinary rails.

这并不是什么新鲜事,至少已经存在了2年了。
它是一个完整的解决方案,需要专用轨道才能运行。这意味着它不是一列可以在普通铁轨上运行的“火车”。

It has no wheels and is suspended on the track by magnetic levitation. There is no resistance from the track. The propulsion power comes from each carriage. Technically, it's flying in the air, just a few centimeters above the orbital surface.

它没有轮子,通过磁悬浮悬浮在轨道上。轨道上没有阻力。推进动力来自每节车厢。从技术上讲,它在空中飞行,距离轨道表面仅几厘米。

The forward power of the maglev train comes from the conversion of the electromagnet polarity between the track and the carriage. S and N are alternately converted to push the train forward.

磁浮列车的前进动力来自于轨道与车厢之间电磁铁极性的转换。 S和N交替转换,推动列车前进。


When it needs to reverse, the control system changes the conversion sequence of each magnet, and the vehicle can drive in reverse. Since there is no need for a gearbox and complex transmission mechanism, its reversing becomes very simple.

当需要倒车时,控制系统改变各个磁铁的转换顺序,车辆即可倒车行驶。由于不需要变速箱和复杂的传动机构,所以它的倒车变得非常简单。
