I would need somebody to provide a set of "open source" open and closed coupler shapes (as well as a chain version as well) to try and set it up. The connecting air hoses would also need to be added to the coupler.

For example, if we get 114mm of movement in compression on one coupler, we will get 228mm of total movement for the two couplers between cars.
Also there are three zones of operation in the model, typically the two displacement diagrams do not show the Z1 distances, ie when the couplers are not in contact with each other. So these distances need to be allowed for. I am also wondering if the "rest" position is correct, would the buffers both be in contact with each other at rest?
See this article, as it tends to suggest that buffers were not in close contact when at rest.
Perhaps the tension and compression slack Z1 values need to be a bit more evenly spread?

The article referenced above tends to suggest that springs were fitted to the draw hooks in "more" recent times.
Otherwise it is probably a good start.
