    Experiment with ballast materials revealed that the best choice for a supporting layer under the track was crushed stone. Railroads started to use crushed limestone and quartz for the track underlayment. These materials proved a great advance over using earth or coal cinders as a support system as they were much stronger and more durable.OPTIMISATION OF BALLAST COMPACTION BY CONTINUOUS,No significant crushing of ballast was observed as a result of compaction.
