The ballast on railways wasn't always grey and if you want your model railway to be authentic you'll need to get the colour and texture right on your layout. The ballast you see on railways today will almost certainly be of a consistent size and colour and made from crushed Granite but it hasn't always been this way. The choice of material has evolved …

Depending on the characteristics and requirements of the rail system and the ballast conditions, there is nuance and variance in how the tamping parameters (like number of insertions and tamping cycle time) are applied. "Each part of this process is set by the operator, so the efficacy and quality of tamping is dependent on their experience ...
