I'm not sure I'm following you, Matt, but on the photo with the new piping drawn-in, you have the steam exhaust pipe running to the sand delivery pipe. It has nothing to do with the sand pipe, and should simply continue straight-on to the smokebox. There appears to be some cast-on detail on the smokebox - looks like a damper control, and could probably be removed - it's not on the real one.
On the prototype photo of 89, the exhaust pipe runs along the top of the running board, but it's difficult to see exactly where it enters the smokebox. It appears to be right behind the air pipe which goes up and over the smokebox, and just barely above the running board. There's another exhaust steam pipe terminating in the smokebox, just above and in front of the pipe for the cylinder exhaust, and it appears to come from beneath the running board. I'm not sure where its source is, though.
