Don't think either CR450 models can go that fast. They should not be designed for a max speed that is much higher than their intended operating speed. That would be wasteful. Existing CR models so far all have their max speeds only slightly higher than their operating speeds.
600 km/h will be for the next generation maglev trains:
Could it be a boosted/specifically designed CR450 EMU intended to beat the record set by TGV in 2007? I recalled the CRH380AL and CRH 380BL (actually passenger EMUs, not ones built for experiments) being tested up to 486kph and 487 kph respectively in 2011 period just prior to the opening of the Beijing-Shanghai HSR. Yet, the Beijing-Shanghai HSR was designed to operate at 380kph at most (but reduced to 300kph following the Wenzhou tragedy, not operating at 350kph).
Maglev appears to be a long way off. I don't recall any high-speed maglev lines being under construction or approved by the State Council. CRRC Qingdao Sifang's 600kph maglev prototype appears to be for testing only at this stage. The Chengdu-Chongqing HSR mentioned in this image is a new regular HSR under construction.
Didn't know CRH380 can go this far above its specs in max speed. If the CR-450 models are built in the same way, yeah there are indeed chances for them to try 600 km/h on wheels even if it is just a backup for the maglev approach.
