Santa Fe switcher in the early 1980th

Sorry Reinhard. As I said, it will take an ATSF modeler to really answer your question about the GP-30 and the GP-7. Just goes to show that a person shouldn't jump in to things that they're not that familiar with! There were still plenty of GP-7's 9's and 30's running around here in 1980, although many of them were not in very great shape.
