I've been looking at a number of track photos and reading about the use of crusher fines for ballast, etc. What I've seen is ballast that, in most cases, includes at least some rock with a 'feature size' that is close to the narrow dimension of the sleepers--that is, rock chunks that, to scale, are equivalent to about 8" or so in diameter.
Are there more uniform materials that work well for ballast that are much closer to scale? I was wondering about aquarium tank rock, for example (although probably not the day-glo chartreuse stuff
).
