You are looking at a PART for your Lionel F3 diesel engine, perhaps others. It is an original part. This is a very hard to find part.
As you can see, it is more than just the board--it has the bracket, wiring harnesses, and even the switch.
We ordered it in YEARS ago from Lionel, but we never used it. Today, it is obsolete and not easy to come by.
Fits F3 diesels (likely from late 90s, 00s) with two motors. May fit other diesels, but that is up to you. Please know your need/application before purchasing.
CONDITION: C-9, New Old Stock. Does come in the worn original Lionel plastic with the parts department label. Only listed as C-9 because the Lionel plastic packaging has been opened, and it has clearly been taken out for these pictures.
