How To Pick The Right Ballast For The Most Realistic Model Railway
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 over time. In the 18th and …

A new parameter for classification and evaluation of railway ballast
The physical condition of railway ballast should be regularly inspected and accordingly, ballast cleaning should be carried out to maintain the safe operation of a track. This paper reviews current methods commonly used for evaluating the degree of ballast fouling, and due to their limitations, a new parameter — ''relative ballast fouling ratio''— is proposed.
