As to whether or not it did test runs on rusty track, that’s completely unknown. It’s looks like it’s parked on rusty track — but the rocks in the pic look rusty to and it’s clear the color in the photo has been ‘enhanced’ in some ways. But who knows where it was tested. Furthermore, if it’s going to run on rusty track in real life, shouldn’t it be tested on them as well? Shouldn’t it be tested in worst possible conditions?

It seems you’ve got a gripe with China, but don’t go overboard..
