I was looking at a listing on Ebay for the Lionel Lehigh Valley NS Heritage ES44AC. While looking at some of the pictures, I noticed that the side of the cab says ES44ACE instead of ES44AC. I've never heard of an ES44ACE, and I know that the real NS 8104 says ES44AC, but maybe it was different at some point. I wouldn't let something like this stop me from buying it (even though I wasn't going to anyways), but I would like to know if there is a reason behind it or if it is just a mistake.
