PCRR: thanks again for helping clarify things. For the record, I use tubular O27 track and switches (all 42" ones from now on). I learned last Christmas that none of my stuff runs on my 27" curves so I will only use 42" and 54" and 72" curves now and only my 42" switches. No more 27" curves or switches.
PCRR: like I said, I think it's a very sad statement that the train won't run on the track that comes with the set. Whether it's 31" or not, the track that works should be in the set.
TinplateBob: I took some pictures that I am including so show the connection. I am NOT ignoring or forgetting your strong advice on the lift pin, be assured. I would still appreciate some tips on removing it if you don't mind.
Allan: So much for me to learn!!!

PICTURES taken last night:
Both trucks are on straight track, even though the tender is slightly into the curve. Even on straight track the 2 'boxes' don't line up - they can't really since the links are in the middle of the box meaning one, or both, has to be off to the side when coupled.
On RealTrax: hopper's link is on the top in the picture. You can see how it pushes on the inside of the box on the tender pushing the tender's truck outward
This is on a 42" curve with the hopper's link on the top in the picture.
This shows both layouts that I tested on.
The engine runs well on this all 42" curve oval:
The result on RealTrax. Notice how the tender's trailing truck got pushed off of the rail.
Notice how the hopper lands up 'leaning' going around even 42" curves.
