200km/h and 160km/h at a Polish High-Speed Line (CMK) 

That was probably one of the fastest videos I've ever uploaded here. The line is soon to be certified to speeds up to 250km/h, but as of january 2024 its max line speed is 200km/h. The Pendolino ETR610 that can be seen in the video set a world record for Pendolino train type in 2013, going 293km/h on that exact line.
