Region issue. – Train Station 2: Steam Empire Review

It’s a great game, and I enjoy the simulation, myriad of tasks, the engines I collect. The issue is that when I unlock a new region, it doesn’t view the other trains that we haven’t collected from the first region(I am unable to view the Mallard and Erie in the container shops). Can it be possible to still collect?
