I sold a 8 of of the F9s in the last 2 years. 4 went for 50 apiece. 2 went as a pair for 125 I think, they had low end DCC decoders. These locos will run with HO size decoders. The last 2 I sold for 200. I had converted them to Pennsy. remved the pilots and added passenger pilots. I cut off all the cast grabs and replaced them with wire. I removed the steam generator exhaust on the hood and patched it. Then I added PRR antennas and painted them PRR Freight scheme - very dark green with singel yellow stripe. I think in the 30 years I had them, I replaced one axle.
