If Darwin was correct, the geological stockpile should provide examples of organisms with a partial accumulation of said new traits and features, but not complete enough to have quite made it into the menagerie of life. Although they didn't produce new lines of living things, these 'attempts' would be, should be, preserved as fossils.
There are thousands upon thousands of examples of such organisms that exist as living species today. We don't even need the fossil record.
Just work your way up through increasing levels of complexity. A very limited set of examples:
Choanoflagellate
Sponge
Cnidarian
Simple worms
Hagfish
Sharks
Bony Fish
Lobe finned fish
Amphibians
Reptiles
Mammals
All exist today. And many predecessor organisms exist in the fossil record. Just consider Tiktaalik - a transitional fossil between fish and amphibian from about 360 mya.
I'll get to your Chengjiang/Burgess shale silliness later.

Glad to see I've convinced you that Darwin was incorrect.
1. The fossil evidence from the Chinese discovery is a clear contradiction to Darwin orthodoxy.
Understand this: the discovery turns Darwin's 'tree of life' upside down!
a. "Charles Darwin (1809–1882) used the concept of a tree of life in the context of his theory of evolution. In
On the Origin of Species(1859) Chapter IV he presented an abstract diagram of a theoretical tree of life for species of an unnamed large
genus "

He begins with one simple organism at the bottom, and more and more as they become more complex.
b. The sudden appearance of new body forms, new species is the very antithesis.
"THE ABRUPTmanner in which whole groups of species suddenly appear in certain formations, has been urged by several palæontologists—for instance, by Agassiz, Pictet, and Sedgwick—as a fatal objection to the belief in the transmutation of species. If numerous species, belonging to the same genera or families, have really started into life at once,
the fact would be fatal to the theory of evolution through natural selection."
Darwin, "On The Origin of Species," p.302
2. Even from Time magazine:
"Over the decades, evolutionary theorists beginning with Charles Darwin have tried to argue that the appearance of multicelled animals during the Cambrian merely seemed sudden, and in fact had been preceded by a lengthy period of evolution for which the geological record was missing. But this explanation, while it patched over a hole in an otherwise masterly theory, now seems increasingly unsatisfactory.
Since 1987, discoveries of major fossil beds in Greenland, in China, in Siberia, and now in Namibia have shown that the period of biological innovation occurred at virtually the same instant in geologic time all around the world." Extrait de
a. Darwinians can not explain where all the DNA information came along in such a short period of time

3. BTW.....Darwin recognized that the only proof of his theory would be the fossil record.
“Consequently, if my theory be true, it is indisputable that before the lowest Silurian stratum was deposited, long periods elapsed, as long as, or probably far longer than, the whole interval from the Silurian age to the present day; and that during these vast, yet quite unknown, periods of time, the world swarmed with living creatures.
To the question why we do not find records of these vast primordial periods, I can give no satisfactory answer.”
“
The case at present must remain inexplicable; and may be truly urged as a valid argument against the views here entertained.”
