I would think the only place you could run a Rheildol loco would be between Porthmadog and Boston lodge, though I would have thought they would be ok on the WHR.
I did make a quick trial model early last year to see if the loco's would pass using std MSTS track (just).
Yes they would go part of the way up the line - not sure how far though... Tan-y-Bwlch probably, although not sure if they would fit things like the level crossing at Minfordd (?) or is it Penrhyn (?)
Interesting VOR models there Kevin. The VOR Davies & Metcalfe 2-6-2T design was very close to the Manning Wardle 2-6-2T supplied to the Lynton & Barnstaple Railway - "Perchance the MSTS L&B is not sleepth"?

Totally narrow minded and a Isle of Man Railway nutter....
Don't forget the Isle of Man has more narrow gauge than you can wave a stick at. Steam - Diesel - Electric and even Horse power - Visitors most welcome...........
