Improved Ballast Texture?

[Accurate]

One of the opening pictures shows a white DB locomotive at a station. I noticed that there was a common ballast spreading from the track to the platform. It looked like at least a meter of ballast and the ballast looked much better than the stock stuff. Any idea how to get this ballast/texture?

Ah ha, I can understand why given the poor quality of the texture for gravel ballast. Nuts, I thought that there was hope to at least get something that matched the track's ballast. Grrrrr.
