I've just been watching a documentary on the building of the Liverpool to Manchester Railway by George Stephenson. Where the line crosses Chat Moss, he built a 'floating' track bed using bundles of brushwood and stuff because the Moss just swallowed rock and the normal embankment material. That line is still in use today, and as the train crosses it, it can be seen that the trackbed rises and falls.
My question is "what do they have to do these days in the way of maintenance to ensure the embankment still does its job safely?" I'm thinking more along the lines of those things that are special to Chat Moss, rather than used everywhere.
