A few trial views with a "new" camera....

Great photos, docWayne. The shots looking down the tracks are good, and somewhat unusual for a model railroad. Your long shelves fit right in for this type of shot.

I second this.
In addition I think you really, really should try the helicon focus software on these scenes. While helicon focus is rather expensive, there are also freeware programs that do the same.
