Rail Ballast - Type A

'A' Type Rail Ballast has a nominal size of 53mm. Typically made of the freshest blue rock available and as a result has quite a sharp angular shape. Please note: If you do not require high quality blue rock and the level quality assurance that comes with ballast specifically designed for use by railways, have a look at our 53/20 Rundown material as a more affordable alternative.
