Hello to all the members of Railway Forum! I want to open my membership with a question that I haven't been able to find the answer to anywhere on the web...what would be a fairly representative range of volumes in m3 for the amount of gravel/ballast used in the construction of a two-tracked railway line (I am particularly interested in what this figure might be in the Russian Railway system). I'm sure that among all the members there will be somebody who will answer my plea! Many thanks, and thanks for having me on board.
