When the manufacturers finally stop producing lots of models with coarse NEM wheels, thats when Peco might go finer and use a HO finescale standard which uses 1.1mm to 1.2mm flangeways..
The narrow track gauge is being used around the world, however what should the standard be? I say untill some one comes up with a better solution to my HO finescale standards its best to get on the band wagon and enjoy superior running and easier track construction.
