The two PRR ES44ACs I have picked up so far have the following: 1846 has the 3 blinking Cab Lights out of the box and the 8102 has an occasional Blinking 1 Cab Light (Drive Motor Failure) other than that it is a great engine, sound performance etc.
I have another 1846 to pick up and am going to have the LHS check that one before I leave the store.
On a good note: the 1848 (Non Powered) does not seem to have any electrical issues!
These are my first new Legacy's and really like the look, other than the white roofs/skylights by the engines cab. It is probably correct and matches the Heritage Themes but IMO it just looks weird and detracts from the design and overall great look of the engine.
I am not a rivet counter at this point in my hobby but I really like the quality that Lionel put into the Paint, Trimmings etc. to make the engine look fantastic.
Now just got to get them back up to shape operationally, I will be a happy camper!
