Hello. before reading this Ad on these beautiful diesels I will also have the matching passenger cars for sale separately on my ebay page… Unfortunately i’ve came down to the conclusion of me needing to sell these diesels since i don’t have any TMCC command base or control for them. I’m not able to test to see every feature they hold. besides laying the A units down on the powered lionel fast track that i own and seeing/ hearing them power up. I recently bought a train collection and these units were the only ones that obtained TMCC with the rest of the others having bluetooth built into them . every single steam and diesel engine is fully functioning i can almost guarantee these all work just fine. some key details about the f3s.. The A units one of them is powered and other is a dummy but with features still equipped. Both B units are powered. From pictures you can see they have wear and tear such as some minor scratches. On one of the B units the rear door is stuck slightly open. If you have any more questions or want to see a video of these placed on the track to see lights/ diesel sound start up. Please message me these can also be locally picked up from me here in stockton CA
