Here's something I got and it just says GP model on the box.
It's a K-Line made by New Ray with a part number K922-003 G scale. How do I tell if it's a GP38, or 40 or ??? Got dynamic brake fan section right? Three fans on the rear with the small one in the middle. It has bad axles and the gears are cracked. I'll need to check out the Lionel version before I buy it to see if it suffers from the same issue??
