That's correct, no 156 centre cars, but they were designed to run with driving cars split and added onto other sets to run as 3-car units of necessary and without (AFAIK) the need for any modifications as with 158s.
The 156s need a gangway conversion plate to run as 3 car units. I believe that the inner unit gangway is slightly smaller than the cab end gangway. The last time I saw one fitted was on a 156 in Liverpool many years ago (about 2005). You can tell if they still have them as it looks like there is a thin sheet of metal sticking out from the top of the inner gangways.
Not sure about the other 15X units.
