At the moment the company goes into receivership the director of this company has to lay the Tasmania tile (if the company owns the Tasmania private).
He also writes on my questions around rules differences (which I may have remembered wrongly in my question):
Your rules are right. I just realised that I put the wrong (older) rules on my website with different rules concerning discarding permanent trains when companies go into receivership. Joe might downloaded that one...
But in no rules seven 2-trains are mentioned. There are always six 2-trains, and the rules say that. It could have happen that Joe Black got seven 2-train cards due to an sorting error.
