I think that the only way the 3 rail community is going to get a reasonably affordable prototypical CZ train is for 3rd Rail to make it.
I thought that Atlas would do this but Atlas doesn't seem to be able to produce all the cars for whatever reason. The cars that Atlas has released are excellent.
3rd Rail is probably reluctant to start a CZ project because of the Atlas head start.

If Scott announced a CZ project in the next few months, there's no doubt it would beat Atlas to the finish line.
