How fast can a train go?

The world speed record, which still stands, was set by a French train à grande vitesse (TGV) in 2007, when it topped out at 574.8 km/h (357 mph).

China has just introduced the CR450, which routinely runs at 400 km/h, but is potentially capable of topping out at 450 km/h in everyday service.

I got to ride the mag-lev in #Shanghai, where the in-car speedometer reached 430 km/h. A lot of tech, and electricity, for results that conventional HSR can now achieve.

I take a look at The State of Speed in passenger trains around the world in the latest dispatch from my new newsletter, HIGH SPEED. (Spoiler alert: the US and Canada are the tortoises among the hares.)

@straphanger People make fun of California High Speed Rail for specifying 360 km/hr rather than something slower. I think the argument is that it is too expensive or something. (I mean, it is expensive, but whether because of the speed is one of those complicated questions that may lack a simple answer).

@straphanger When did you try it? Because I tried it in July, and it only went to 300 km/h.

@straphanger The Japanese SC maglev set a record of >600 km/h. JR is now deploying the technology on the Chuo shinkansen line. Source: https://en.wikipedia.org/wiki/SCMaglev
