1/43 = ?? railway scale

Have an idea running round in my head after a couple of discussions at a diecast show yesterday and was wondering what railway scale is the same or close to 1/43 as there is a fair range of buildings to choose from plus other bits n pieces that might be required

i think its 1/87 railway stuff

British O gauge is 1/43.5: http://en.wikipedia.org/wiki/O_scale

I have o gauge buildings and workshops for projects
good scale

The O guage is the larger scale, the one we have running around our loft (my sons !), your traditional HORNBY set is OO guage, and thats 1/76 scale..... Like EFE models etc, that are designed for the rail enthusiast......
