Size and Section of Ballast in Railway – Civil Engineering
The size of the ballast used in railway track varies from 19 cm to 51 cm The stone of size larger than 51 cm is not preferable due to poor interlocking property The stone of size larger than 51 cm is not preferable due to poor interlocking propertyThe size of the ballast used in railway track varies from 19 cm to 51 cmThe stone of size larger than 51 cm is not preferable due to poor interlocking property The bestrecommended ballast is that which contains stones ranging in size from 19 cm to 51 cmBallast Size In Rail Track mapymyslieduplBallast Size In Rail Track According to brian solomons book railway maintenance the men and machines that keep the railroads running today the typical layout for a wellballasted railroad track system is stone lined to the top of the railroad ties protruding roughly 14 inches to either side tapering away on a 3to1 slope to an eventual distance of 9 feet 10 inches from the centeroftrack with Ballast Size In Rail Track thaiphysiode
