I have a bag of very old John's Labs ballast (and glue) for N scale. When I used it, the grains were so fine it almost looked like plaster. It's one of those things -- scale may be too fine to distinguish.
yes, i think thats exactly right,
- i mean if you calculate the scale size for ballest, its gota be small!!
- Or thinking for a moment, on a full scale track, how many induvidual peices of stone there are between each sleeper, and try and imagen that number of peices of model ballest between our 2mm sleepers!!!!

ok, i did a bit of number crunching,
- if a peice of full size ballest is 100mm [4"] diameter, scaled down to (british, 1:148) Ngauge size, it would be a diamater of 0.675mm [0.026"]
- and if it where a larger, 250mm [10"] peice of ballest, scaled down, its still only 1.689mm [0.066"]
- Or, if we try and do it the other way around, on average (as best as i can measure), the ballest the im using at the moment is about 1mm [0.0039"] dia, which, scaled up by a factor of 148:1, ie "full size" is 148mm [5.826"]
So, in conclusion, im actually rather surprised how accurate our ballest is, and after all, even in the real world, different area or different railways have different sized ballest.
