I have the original 2007 Hogwarts Express (#7-11020) set from about 10 years ago. When it was originally released, there were two extra coach options for it:
#7-11142: Express "Add on 2-pack" (which contained two coaches, including what we might call a "combine" in the USA), and
#6-35229: Hogwarts "Dementors" coach.
I haven't acquired either of the above yet but plan to some day. I see that Lionel has now rereleased the Hogwarts Express in 2015 and also rereleased the Dementors coach with the same number (#6-35229).
Question #1: are they the same coach, and are they interchangable? Meaning, does a LionChief coach work on a layout powered by a standard Lionel transformer?
Also, Lionel released in 2018 a standalone coach (only one this time, and not the different combine but instead just a regular coach). Boo, as I want that combine! This is numbered #6-85264.
Question #2: without car numbers to compare, is this just the same coach as in the previous 2-car set?
Question #3: did Lionel announce why they aren't rereleasing the combine car? I would think more people would want a different style coach body in their trains.
Thanks!
