Ballast size to use help

[Bigsteel]

i use fine ballast,i prefer the small size seeing how real ballast is usally 2-3in wide,the fine looks more scale to me.but medium is good also (just watch your flangeways).and since your ballasting a yard,you may want to cover the ties a bit more than on a main,since yards are much slower and typically are not maintained as well. for color,try mixing your grey balast with some cinders,yards were given the worse of the ballast on the line since it didnt need as much support.heres an image for refernce that i used: http://www.zuula.com/img_srch/img_frame....yard&lna=0--josh
