I am not a Hornby enthusiast, but have one gauge 00 locomotive that I count as being one of my best runners and most trouble free - the Hornby c35 Hymek.

Personally I thing that the "rivet counters" have demanded so many changes to be made by the manufacturers, that decline in models running qualities was to be expected.
I will agree that better and stronger electric motors was a must to increase an engine pulling power and the ability to power pickup from all traction wheels.
Why change a proved and accepted method of traction, just for the sake of changes.
