Hi, These are the TESTED MINT #8970 Pennsylvania F3 AA Dual Motor Diesel /Non-Powered Units and the #8060 Pennsylvania F3 B Unit that Lionel made circa 1980. Our Opinion is that they are generally in Mint Condition. Original Boxes. All Original in our Opinion. 

Units were oiled then TESTED with conventional transformer and performed great forward, reverse, lights. Great set!

I think my test was more than it had been run. Quiet fast smooth runners!

 

Please see my store for many other great trains!
