We're well off track for building sizes aren't we

.
You said... and I understand that '00FS' champions want to adopt 16.2mm as their gauge standard. At least in N gauge it's all 9mm rather than the choice of 16.2, 16.5, 18, 18.2 and 18.87 or whatever ............
***Yes, the insanity continues in 4mm scale!
There is some sensible logic in using slight gauge narrowing thru pointwork, but its a compromise yet again to accommodate poor RTR wheel settings by the mfrs... The DOGA fine standard remains at 16.5 with 1mm flangeway gaps (similar to EM for wheel and critical turnout dimensions), and EM and P4 will always follow their own path too. The 16.2 movement is based on solid fact as far as running qualities with unmodified RTR is concerned but will remain a fringe movement I think...standard 16.5 won't fade away.
N is certainly the only RTR scale thats managed to keep semi-sensible consistency in track standards.... and yes.... The flanges are certainly far better than they were, but all are still visibly large - I sense a certain pique in your response but in fact thats definately not a criticism of the scale or those that model in it by the way, just a simple statement of fact, and an inevitability when the market includes a mix of track and modelling preferences.
As long as we all enjoy the hobby in our own way of course, this is all just words...
