    Railway ballast importance. I'm restoring the relative importance of quartzite's use as a railway ballast that was changed in a Sept. 2009 edit. The author of the reference (name=MII) had data that supports that most crushed stone was not quartzite, and crushed quartzite was small part of construction use. These I don't question.

    If ballast is badly fouled, the clogging will reduce its ability to drain properly. That, in turn, causes debris to be sucked up from the sub-ballast, causing more fouling. Therefore, keeping the ballast clean is essential. Bioremediation can be used to clean ballast. It is not always necessary to replace the ballast if it is fouled, nor must all the ballast be removed if it is to be cleaned. Removing and cleaning the ballast from the shoulder is often sufficient, if shoulder ballast i
