I tried this. Two R610 between the point and R628. It brings it to 67mm parallel, but you then need about one and three quarters R610 on the straight. That's really awkward, and cannot be fit with standard track. To me it really looks like a serious error in track geometry. I am surprised no one else on the forum has reported this. It's important enough to inform other potential buyers of express points of these issues. I invested in this but can't use it the way I want. So if Hornby is going to fix this, I volunteer to receive the corrected pieces. Of course, with flex track you can fit anything, but that's not the point here. Our track is not (yet) fixed. Still trying out different lay-outs although we are homing in. The track is built and rebuilt occasionally. I do the track, my 13-year old son manages the trains. Together we started landscaping a bit. Lots to do over the next years.
