Thanks locojoe. I am sure you are in a much better position than most of us to make these judgements.
There is an article in the LMS Journal no.25 on Stanier's proposed 4-6-4 which would have pushed steam loco design to the limit of the British loading gauge. It would have needed a mechanical stoker and had a boiler pushed to 300psi.
It is another article I have not yet had the chance to read but have skimmed it. The theory is put forward that it would have been the equal of a Deltic so quite an impressive machine. Sadly the war stopped progress and steam design for UK railways was never pushed any further than the Duchess, which must therefore remain the ultimate!
Best wishes,
