Hydraulically tilting train - GIF

[Claudio HG]

Not an expert in such things, but this is similar to the Pendolino. They overcome the risk of derailing by tilting the car in a way the barycenter goes off to neutralize the barycenter shift caused by the centrifugal force. This allows the use of regular railways designed for lower speed trains, but at much higher speed, actually pretty cost effective. The operation seen in the GIF is manual, while -AFAIK- Pendolino is electronically controlled with sensors and each car may tilt independently and automatically.
