For an interesting look at the current state of railroad and aviation computer graphics imaging technology in China, consider viewing the mix of actual and generated images in THE BATTLE AT LAKE CHANGJIN, now available in English language version on YouTube:

And when you have watched it, you might want to consider what the purpose of this movie, the most expensive production ever in China (reported at 200 million US dollars in 2021), might be.

Right about 32:30, it sure looks like a genuine video teaser of a KF-1, North British built 4-8-4. The SY shown just before that appears to have a JS tender, fake feedwater heater and pilot air pump shields, cut down stack and extra lights in front, not sure what that's supposed to be.... The scene of blowing up a multi span truss bridge looks real to me, but I bet plenty of fake images do too.

They appear to be gearing up to paint American intervention in Communist power grabbing as massive imperialist aggression for trivial capitalist reasons, overcome by plucky Chinese courage. But that's not really a suitable subject for this forum. Mr. cook was right though: think about it for yourselves.

Perhaps well-spent if the Chinese government does decide to have an adventure in their 'wayward province' Taiwan.

Some of the animation and Foley sound suffers from a sort of stop-motion artifact problem -- too much resolution compared to what film would actually capture.
