Just to clear up, Lionel still shows this board as available. It is an ACDR. Additionally the 18064 used an R2LC R2IR.
I have both of these from an original engine if some one need the parts.
This engine used the IR harness. I asked about the code difference, and I really could not get a straight answer about the R2LC. This falls into that history thing, from the previous employees of Lionel. Not much documentation. G
