Famous last words! Appointment abruptly cancelled, so I have been 'FREED!' (sadly this particular tediously boring event will come around again for my participation, but never mind...).
Now, I have a 'discovery' to reveal. The Oxford Rail wheelsets in the LNER design 6 plank open and GER design ventilated van are
potentially incompatible with the standard Hornby point. (I have to wait a short while before I can test the wheelsets in the Pilchard.) The wheel form is subtly different from Hornby's and the result is that these wagons can derail on the sample points I have, because the check rails do not suficiently restrict the wheelset from mounting the crossing when travelling in the facing direction.
I cannot really offer any more useful information: for a start, these sample points (and other set track pieces) are well used Hornby track taken from a late friend's layout when it was altered probably a dozen or more years ago, to enable me to test his purchases for compatability, and is in good condition but well used: so there's the first problem, is it fully representative of current set track from Hornby, and also Peco and Bachmann?
And then the second problem, until now I have never tested any Oxford product on set track, as there was no longer a requirement; and for my own purposes the Oxford items I own have been fine on a layout that is a mix of three flavours of Peco Streamline and various 'kit' OO points and SMP track.
I don't recall anything in the way of problem reports from use on set track, but then I haven't been looking out for these...

I have replaced all the couplings on Oxford product to either Bachmann tension lock or Kadee as appropriate, using my 'own standard' positioning. But this is nothing 'out of course';
every single vehicle on the layout the coupler positioning has been altered, simply to ensure that whatever brand* - or kitbuilt - they are all truly compatible in operation within coupler type. It's a chore, but RTR OO is a jungle in this respect, and even the NEM coupler pocket which had the potential to resolve this doesn't, although it does bring the benefit of quick and easy adjustment - most of the time...
* List of currently operating RTR OO brands so adjusted to date, Accurascale, Bachmann, Dapol, Hattons, Heljan, Hornby, Oxford, Rapido, Sonic. Any current RTR OO brand not mentioned is because they haven't made anything I can use, thus far...
